Testing Methodology

Background:

This Midas Tac 5-25×56 is the third scope I have reviewed from the relatively new Athlon optics company. Started and run by a couple of optical industry alums, Athlon sources optics from a number of different overseas OEM’s which are made to the companies’ specifications. Based on the company’s growth rate and customer satisfaction, the Athlon guys appear to be quite good at this. Certainly the scopes I have seen from them have proven predictably reliable and with features that I judge to be well chosen for the marketplace. Furthermore, Athlon appears to have a very rigorous quality control apparatus in place, as the scopes I have seen have much lower than average deviation from specifications when it comes to adjustment magnitude, reticle size, and reticle alignment. The predictability of their function is starting to make them rather dull to test.

Today’s scope, the Midas Tac 5-25×56, is a new scope being added to their existing Midas TAC line. It’s sort of a gap-filler. It is of similar glass quality and magnification to the existing Midas TAC 6-24×50, but has a larger 56mm form factor more in line with the higher end ARES ETR 4.5-30×56. You could choose to see it as a lower cost alternative to the ARES ETR 4.5-30×56, which it is similar in size to or as a larger alternative to the Midas TAC 6-24x that it shares relative glass quality with.

Unboxing and Physical Description:

We may as well start the theme of this review right here. There were no surprises in the unboxing. The Athlon Midas TAC 5-25×56 comes with a lens cloth and manual just like its little brother the Midas TAC 6-24×50 did. It is styled very similarly and, from the objective to the tube to the eyepiece, it just appears to be a slightly bigger version of the same idea. The 5-25×56 is about 4oz heavier, just under an inch longer, has a 34mm instead of 30mm tube, and, of course, has a 56mm objective instead of 50mm. Probably, the biggest highlights are the 32mil instead of 25mil total elevation adjustment and the larger 5x instead of 4x magnification ratio.  32 mils is actually a pretty large adjustment range at any price these days, and the Midas TAC 5-25×56 is not a high cost optic.

The manual included with the Midas TAC 5-25×56 I received for testing appears to be the same one as the Midas TAC Athlon Midas TAC 6-24×50 from last year. In fact, its section with scope dimensions has not been updated to include the 5-25×56. I received this scope just before they hit the market generally, so it is likely from the first run and the manual you will receive had not yet been printed. Hopefully they update the troubleshooting section of the new one to remove the suggestion to directly support the barrel with a sandbag, as well as the text about excessive grease in the barrel. There should be no grease at all in a barrel at the time of firing.

Reticle:

The Athlon Midas TAC 5-25×56 is available with just one mil and one MOA reticle option. The mil option, the APRS3, is a typical mil hash Christmas tree reticle with a floating dot center and .2 mil increments horizontally out to 6 mils then .5 mil increments after that out to 9 mils, at which point there is just a thick crosshairs. Vertically, the reticle is graduated in .2 mil increments for just one mil. At that point, the top half is graduated in .5 mil increments out to 9 mils and then it becomes a thick crosshairs, while the bottom half is graduated in .5 mil increments out to 7 mils, where it goes back to .2 mil increments until 10 mils, at which point it becomes a thick crosshairs. While there is probably some rationale for the alternating use of a .2 mil graduation system and a .5 mil one, this is not fully explained anywhere, though even if it were, I likely wouldn’t agree with it over the consistency of sticking with the .2 mil increments throughout. Both vertical and horizontal crosshairs are numbered every 2 mils and are on the thinner than average side when it comes to line thickness. The Christmas tree section has rows of dots every mil below the central crosshairs. Each row is graduated in fine dots every .2 mils and a thicker dot every mil. The MOA based reticle, the APLR4 FFP MOA, has essentially the same appearance as the mil reticle. Unsurprisingly, its graduations are spaced 1 MOA apart. The APRS3 Christmas tree mil hash reticle is very much in line with what I see the industry converging to and the alternation between .5 and .2 mil increments at places is really the only bone I have to pick with it.

When tested, the reticle showed a very slight cant of ~.5 degrees counter-clockwise relative to the adjustments. This is not an amount of deviation I would be concerned about. The reticle graduations were correctly sized.

Comparative Optical Evaluation:

For optical comparisons with the Athlon Midas TAC 5-25×56,I had the entire suite of sub $1K FFP mil/mil precision riflescopes that have been part of this ongoing series of reviews. In order of arrival, they are the:  Sightron SIIISS624x50LRFFP/MH, Athlon Ares BTR 4.5-27×50 FFP IR Mil, Athlon Midas TAC 6-24×50, Meopta Optika6 5-30×56 RD FFP, Sightron S-TAC 4-20x50FFPZSIRMH, and Nikon Black FX1000 6-24x50SF Matte IL FX-MRAD. It should be noted that, at the time of this writing, the Nikon was not present to be compared as the example. It had proved defective, was returned, and its replacement had not yet arrived. Testing of all the scopes was done in accordance with the same methodology that I have used now for a number of years.

On balance, the Athlon Midas TAC 5-25×56 is optically the best of the Athlon scopes tested and on the better side of the field of sub $1K scopes overall. Its strongest points were field of view, depth of field, low light performance, and contrast. In these aspects it was either the best performer or close to it. The TAC 5-25×56 was more middle of the pack when it came to resolution, eyebox, barrel distortion, stray light handling, and chromatic aberration. In no aspect of optical performance that I measured did the TAC 5-25×56 test in the bottom 3rd of scopes tested. I think that the avoidance of any real weaknesses might speak as well for the scope as the overall above average finish. There is something to be said for an optical design balanced well enough that it really doesn’t stumble in any single design criterion.

Mechanical Testing and Turret Discussion:

The Athlon Midas TAC 5-25×56 features a virtually identical large uncapped 10 mil per turn zero stop elevation adjustment to that of the Midas TAC 6-24×50. Both scopes adjustments have the firm, postitive, “clicky” feel.  that comes from a high ratio of click force / rotation force between clicks. This does mean that you will occasionally over-rotate with them or lose click count and have to look at the dial. The Midas scopes are not the most difficult in this regard, but it will happen occasionally. I think the ratio of click force / rotation force between clicks is a difficult decision for optics makers. People generally greatly prefer this “clicky” feel and dislike the squishy feel that you get if the ratio of click force / rotation force between the clicks is low. However, it is difficult to have that positive “clicky” feel and also have a knob that the user won’t occasionally over rotate or loose count and have to break position to check on. Athlon has experimented both ways on this in the past and has understandably gone with the customers preferred feel. You do not make money telling people what the ought to want, you make it by producing what they already want.

Just like the smaller Midas, the 5-25×56 has a smaller capped windage knob. This knob is a 10 mils per turn knob that is marked 1-5 in each direction. The windage knob on my 5-25×56 is significantly stiffer and “clickier” than it was on the TAC 6-24×50, and, as a result, is easier to over-rotate or lose click count on. The power ring and parallax knob on the Midas are on the looser side of average with the euro-style diopter ring about average. The diopter rings on both Midas scopes seem to have a bit more correction range than on most scopes which I classify a win since I recently had an issue with a competitor who had so little range that I couldn’t even focus my 20/20 uncorrected eye all the way back to its optimum 20/15 or so.

The Midas TAC 5-25×56 elevation knob’s features and design are common to all of the Athlons I have tested so far. They are 10mil per turn and feature Athlon’s particular zero stop system, as well as an outer knob with the mil graduation markings on it that can be repositioned. Repositioning the markings to read zero at the rifle’s zero is done in the common way. The outer knob pops off and can be repositioned after removal of a single screw in the top. This outer knob is toothed with enough teeth that its markings will properly line up with the actual detents instead of landing between as some others have done. The zero stop system is one that both Midas TAC scopes share with the Ares BTR but that I have not seen on other optics. As is common, the whole elevation knob on the Midas screws up and down as the adjustment it rotated. This attribute forms the basis of both the zero stop and the simple scribed turn indicator. The zero stop consists of a brass disc they refer to as the “zero stop locking plate” located under the removable outer adjustment sleeve. This disc can be repositioned using three set screws. So, basically, you zero the scope, remove the outer sleeve, loosen the set screws, and move the disc so that it is lying flat on the saddle with its stop protrusion immediately to the right of the stop protrusion on the scope saddle. You then gently tighten the set screws and replace the sleeve and its screw with the proper alignment of the zero. This zero stop is very inexpensive to make, in addition to being quite functional. It also has the same advantage as most plunger style systems in that you can set it independently of the markings to give you a few tenths of adjustment below the zero if you want. It is a well designed system and I’m a fan.

In testing, the scope tracked absolutely dead nuts from 0 up to 17.4mils, returned to zero fine, and then tracked down from zero right on the money to 17.1mils for a total travel of 34.5mils. This travel range is even a bit more than the already generous 32mils advertised. Unsurprisingly, the Midas TAC 5-25×56 also tracked fine to the 4mils each way that I can measure horizontally and showed no zero shift with adjustment of the parallax, diopter, or power ring. The parallax knob even showed exactly 100yds when focused at 100yds and those things are never right.

Summary and Conclusion:

The pattern emerging with these Athlon scopes is that they are solid predictable performers with good value at their price points and with the most in-demand features. The quality control on the three scopes I have seen has been superb, as two of the three showed no measurable deviation at all from perfect in adjustment increment and the other was still better than average. Similarly, all three had properly sized reticles and none had cant of more than .5 degrees. This is a rather impressive record.

Optically, all the Athlons I have tested have met or exceeded my expectations. Overall, this one was the best performer, landing well on the higher performing half of all the sub $1K scopes tested. Larger 56mm scopes are not my favorite, as I typically see little gain for the extra size and weight of over 50mm scopes. In this case though, you do get significantly more elevation range, and the optical design itself is a little better optimized than either of its 50mm brethren.

The street price on this Midas TAC 5-25×56 is around $850, making it about the same as the Ares BTR 4.5-27×50 and ~$200 more than the Midas TAC 6-24×50. All three of these scopes make good arguments at their price points so I think that Athlon has done a pretty good job of the tricky work of product positioning. It is not hard to see why the company is having such success.

Here is Your Pro and Con Breakdown:

Pros:
– Optics are significantly better than average at the price and well optimized
– Tracked perfectly
– Properly sized reticle with very little cant
– Athlon’s QC is starting to look pretty superior
– Very simple effective zero stop that lets you chose travel below zero if you want.
– Full 10mil/turn knobs
– Superb 32mil elevation travel
– Reticle design in line with current trends
– Good warranty and reputation

Cons:
– 56mm objective does add size and weight
– You will occasionally lose click count on the “clicky” adjustments and need to look at the graduations.
– No illumination.
– Basically no extras like scope caps, sunshade, or bra
– Relatively new company with short, though good, track record

Testing Methodology

Background:

Sightron is best known in the target shooting community for producing solid no frills scopes at prices lower than comparable competitors. Sightron has always appeared to be low on advertising expenditures and behind the curve on features, but their quality, price, and customer service has been good. Sightron was very late to the party with ffp, mil/mil offerings, and zero stops. For years I talked to them about this and, finally, two years ago, they came out with an SIII in mil/mil ffp. That SIIISS624x50LRFFP/MH was one of the sub $1K, ffp, mil/mil scopes I reviewed last year. Since then, they have come out with both a higher cost SV ffp design and this, lower cost S-TAC which sits at $700 street with an MSPR of $1k at the time of this writing.

Unboxing and Physical Description:

At first glance, the S-TAC 4-20X50FFPZSIRMH appears to share a lot of similarities with the SIIISS624x50LRFFP/MH. They are both long and light scopes with very plain and subdued styling. The S-Tac comes in at 15″ in length and 25.6 oz weight. Both scopes’ turrets are also very similar, being 5 mil / turn with similar styling and feel. The S-TAC, however, comes standard with the better labeled and higher visibility text found on the “tactical” turrets which were an aftermarket option on the SIII and also include a zero stop. I should note that you can now get these updated adjustments (zero stop and tactical labeled turret) in the SIII with the SIIISS624X50LRZSFFP/MH model. These are the only changes from the SIIISS624x50LRFFP/MH I reviewed last year. Unfortunately, to get these additions adds a hefty $150 to the price. To that set of features, the S-Tac additionally has illumination and a flip-up throw lever on the power ring. Neither of these features is to be found on either higher cost SIII scope. In the box with the S-Tac is a lens cloth, plastic flip-up covers, two hex wrenches, a battery, and the same generic-to-all-Sightron-scopes manual that I received with the SIII last year. Said manual was supposed to have been updated to fix a minor error pertaining to angular and linear measurements in the windage and elevation movement table section, but evidently was not, as they are identical manuals. This update not happening could be worse, as it is basically a typo. However, each scope also includes a second supplemental sheet which has a reticle diagram and dimensions for said reticle, as well as a mil ranging formula. The ranging formula was wrong in the SIII’s supplemental sheet and is now somehow wrong in a different way on the S-Tac’s. These are not mere typos either, these are incorrect, non-functional, and non-sensical formulas. The correct formula should be: (target height (meters)/angle subtended (mils)) *1000 = range to target in meters. I am dismayed at both the persistence of the Sightron folks in getting this wrong and the misplaced creativity demonstrated by getting it wrong in a different way.

Reticle:

The Illuminated MH-4 reticle on the S-TAC 4-20X50FFPZSIRMH is very similar to that which was on the SIIISS624x50LRFFP/MH. Both are very simple mil hash reticles with .5 mil subtensions over most of the reticle and .25 for the first mil from the center. The MH-4 in the S-TAC improves on the reticle in the SIII by adding some number labels for the divisions. This may seem like a minor improvement but in practice it helps greatly in avoiding mis-counting and can also save valuable time when making adjustments. Neither reticle has a Christmas tree section, which I am not sure is a bad thing as tree sections can interfere with how well you can see the splash on a miss. The reticle on the S-TAC is also illuminated and it is substantially thicker. I expect these two may be linked since the SIII had a very fine reticle that I doubt would have illuminated well. The illumination on the S-TAC is not just on the center area but instead on the whole of the graduated section of the reticle. I prefer this arrangement. In general, I feel very much the same about the S-TAC’s reticle that I felt about the SIII”s. There is little to either enthuse or repel a prospective buyer in the design. In testing, the reticle was correctly sized and showed no cant relative to the adjustments.

Comparative Optical Evaluation:

For optical comparisons with the S-TAC 4-20X50FFPZSIRMH, I had the entire suite of sub $1K FFP mil/mil precision rifle scopes that have been part of this ongoing series of reviews. In order of arrival, they are the:  Sightron SIIISS624x50LRFFP/MH, Athlon Ares BTR 4.5-27×50 FFP IR Mil, Athlon Midas TAC 6-24×50, Meopta Optika6 5-30×56 RD FFP, Athlon Midas TAC 5-25×56, and Nikon Black FX1000 6-24x50SF Matte IL FX-MRAD. It should be noted that the Nikon was not present to be compared. The example I was originally sent proved defective, had to be returned, and its replacement has not yet arrived at the time of this writing.

Testing was done in accordance with the same methodology that I have used now for a number of years.

The S-TAC was one of the scopes I was most interested in doing an optical evaluation of. This was because the SIII I tested last year was, on balance, the strongest performer optically in this sub $1K series of reviews. The SIII’s consistently good performance across virtually all of the aspects of optical performance tested coupled with its light weight left me quite fond of that optic despite the features that it lacked compared to most of the other scopes in the field. Superficially, the S-TAC appeared to share some of the same design heritage; perhaps it would do well.

Suffice to say, this was not the case. I will go into more detail. Setting aside the currently-absent-soon-to-be-replaced-because-it-was-defective Nikon, the S-TAC significantly under performed all other scopes in the field. It was rather consistent in this, being at or adjacent to the bottom in resolution, FOV, depth of field, low light, contrast, stray light, and chromatic aberration. Its performance highlights were eyebox and barrel distortion, where it came in just behind its sibling. It is not an uncomfortable or tricky scope to sit behind, it just doesn’t resolve things are well as most of the other scopes I tested.  The sum of all this is that the S-TAC was very obviously a tier below any of the other scopes optically and, I would say, was significantly further from the next scope above it in performance than that scope was from the top performer. Given its sibling, I was pretty surprised at this. The performance difference was enough that when I first picked it up and looked though it without a lineup of scopes, I was already pretty sure how it would stack up.

Mechanical Testing and Turret Discussion:

The S-TAC’s knobs are very similar to those on the SIII with the addition of a zero stop. The knobs are 5 mil / turn and have clicks that feel and sound positive, but are not so stressed out that they will skip over detents and make you miss count. I would therefore say that the feel is a win. As on most of the sub $1K series, the zero indicator adjusts independently of zero stop. In this case, you loosen the top screw to change the indicator setting. The knob is only fastened to the adjustment by this screw and so can be easily turned when it is loose but must be carefully lined up while being tightened as there is no indexing. The zero stop is a collar under the knob that locks into place with three set screws. Once you have zeroed the scope, you just loosen up the set screws on the collar and turn it until it snugs under the knob. The actual threading for this collar is above the section that the set screws interface with so the set screws won’t mess up the threads. Probably the best thing about this system is that the zero stop collar has a line on it for each turn above zero. This is very handy, especially since the 5 mil / turn knobs mean you will often be a few turns above. I find this a substantial improvement over designs that have lines but where you are already several up from the bottom at zero and often also at some odd increment between them. Because the lines are on the collar piece that is the zero stop, they always line up right. The least attractive feature is that the collar feels a bit like a jam nut in that the knob will jam itself onto the stop when you turn to it and stick a bit pulling it off. Overall I like the adjustment mechanism with the exception of being only 5 mil / turn and only being labeled for that first turn.

When tracking, the adjustments deviate from true in a non linear fashion.

Going up from optical center:
-At 5.0 mils on the adjustments, the scope is at 5.1mils on the target.
-At 10 mils on the adjustments it is at 10.1 mils on the target.
-Its full range is 11.5 mils on the adjustments at which point it is at 11.6 mils on the target.
-It returns to zero fine and shows no slop in the adjustments going back to center.

Going down from optical center:
-At 6.0 mils on the adjustments, it is at 6.1 mils on the target.
-At 10.0 mils on the adjustments, it is at 10.1 on the target.
-Its full range is 11.9 mils on the adjustments 12.0 on the target.
-It returns to zero fine and shows no slop in the adjustments going back to center.

On the windage, it also seems to deviate a little, showing ~3.05 mils on the target when it is 3.0 on the knobs. I expect it would prove to follow the same pattern as the elevation if I had a target that went out that far.

There is no zero shift with parallax, diopter, or power ring and I saw no reticle cant. The reticle graduations are also the correct size. This degree of deviation from true in the tracking is about average for all the scopes I have tested over the years.

Summary and Conclusion:

There is no getting around that the Sightron S-TAC 4-20X50FFPZSIRMH left me a little disappointed. This is because it was optically a clear step below its peers in almost every dimension tested and, given the performance of its sibling SIII last year, I did not expect that. Though not the cheapest, its ~$699 street price is one of the lower costs in the field and it does have some features not present in all other scopes. Illumination is the most notable of these features, which also include a pull out throw lever and zero stop. The S-TAC is one of the only scopes to be limited to 5 mils / turn though. I don’t think that there is one universal answer in this sub $1K price range of ffp mil / mil scopes. If cost and illumination are important to you and optical performance is less important, the S-TAC has what you are looking for. Ironically, it has precisely the opposite strengths and weaknesses from its sibling SIII. I guess they were separated at birth.

Here is Your Pro and Con Breakdown:

Pros:
-Has some features not all have: Illumination, zero stop, and a detachable throw lever
-It’s zero stop system provides a good indicator of which turn you are on
-Adjustments have a good feel and the correct resistance to them so you don’t miss count clicks
-Sightron has a good warranty and reputation
-At ~$699 street, it is one of the lower cost options

Cons:
-Optically a clear step below the other sub $1K optics tested
-Only 5 mils / turn
-Significantly below average total elevation adjustment range
-Manual is lacking and contains basic errors

Background:

            Meopta is an optics manufacturer located in the Czech Republic. They represent what is probably the most vertically integrated of all sports optics brands. Most scope brands do not actually have any manufacturing facilities beyond warranty repair. Those that do manufacture usually purchase coated glass and often some sub-assemblies as well. Meopta manufactures all the way down to coating and grinding glass. A great deal of their business is done in this OEM capacity, producing parts and sub-assemblies not just for sport optics,but also for a wide variety of other industries, such as medical and aerospace. The first Meopta product I ever used was one of these OEM’d products. The very popular, though now discontinued, original Zeiss Conquest series of scopes were made by Meopta and continue to live on in Meopta’s lineup as the Meopta Meopro scopes.

Like many overseas manufacturers, Meopta has had difficulty with regard to both marketing their products and deciding what features to make for U.S. consumption. Their brand awareness has also been downright terrible. Some of this is understandable, as they were formerly in the Soviet sphere of influence and so were not seen in western markets until after the dissolution of the Warsaw Pact. Much of it has just been lack of good branding, or appreciation of brand value. In the past few years this has changed some. A lot of this has to do with an advanced U.S. based optical coatings company that Meopta acquired a few years ago. The company came with some U.S. based employees who thought like U.S. shooters and changed the thinking within Meopta to a degree. This group also developed the technology behind the Dichro reticles featured on many of the Optika6 designs, though not the example I am testing.

The Optika6 line therefore is a big departure from previous Meopta offerings in that it includes a lot of ffp designs, mil/mil configurations, zero stops, throw levers, and some reticle designs from ILya.

Unboxing and Physical Description:

            The Meopta MeoPro Optika6 5-30×56 RD FFP comes with a nice scope bra, lens cloth, battery, sticker, hex wrench, some spare screws, and a detachable throw lever that threads into the power change ring. There is also a manual, but it is not particularly useful. It has some stats on the scope’s specifications, but it’s directions on use are quite minimal and difficult to follow. I find the Optika6 to be an attractive scope. I am not sure exactly what makes some scopes attractive and others less so, or if there is any universality to what people find good looking in a scope or not. This one looks good to me though. I would describe it as having a softened tactical appearance. This is both figurative and literal in that the knurling on all the controls is rubber and so will not try to strip the flesh from your hands. The stiffness of each knob (paralax, power, diopter, and illumination) is right on. We will discuss elevation and windage adjustments later. Being a 30x 56mm optic with 34mm tube, it is pretty large. It weighs in at 38oz and is 15.4″ long.

Reticle:

            The Meopta Optika6 line comes in several different reticle options. For the 5-30×56, these include a plex reticle, generic BDC with dichro elements, .308 drop reticle, and ILya’s MRAD RD. It is a pity the MRAD RD does not have any dichro on it, as I would have liked to try that concept out. That is secondary though. Having a reticle that can hit at range is the important thing, and the MRAD RD is by far the best option for that.

ILya’s MRAD RD reticle follows the general trend of .2mil graduated, floating dot center, Christmas tree reticles, but with a few distinctions. The first such distinction is that it only has only 1 mil of graduations in the 12 o’clock sector. I like the open top section as it gives you some space to observe a target area through with no obstructions. The second departure ILya has from the norm is that he does less funny business with graduation increments. Pretty much all the graduations are .2 mil increments and there are .2mil graduations in all sectors of the reticle, including the center. Many other scopes keep changing things up. This causes more mental overhead and more mistakes. I never found myself second guessing what a marking was on ILya’s reticle and that is really the goal. Lastly, the line widths used for the graduations and crosshairs on ILya’s reticle are significantly smaller than the average. I’m a fan of finer graduations so I will take it. This leaves the reticle very fine indeed at 5x, but at 5x you’re really only using the scope for observation anyway, so I don’t see a problem with maximizing the reticles use for 15x and greater.

This brings us to the Christmas tree section. At first I was a big proponent of Christmas tree sections. The concept appealed to me because I really like more utility in a reticle. I thought that trees would make for faster measurement of shot correction, give you a faster way to make corrections in a pinch, and extend your total drop compensation range. In practice though, I have experienced less gain than I expected in these areas, and found a big trade off when it comes to seeing splash. Even when using a reticle with a tree section, I have continued to find it more accurate to measure for shot correction by moving the reticle to get read outs at right angles. Using the tree is both less accurate (big vertical gaps) and only works if your miss lands in the tree section. Not shooting strictly timed competitions (or ones that specifically contrive to disallow adjustment of the scope on some sections) I have found no speed advantage. Finally, most scopes now have adjustment range sufficient to any distance that I am confident of hitting at anyway. I really don’t do more than 15mils in drop ever and virtually every scope will give you that on the elevation turret. So, I have become uncertain as to whether or not I want a tree section at all and very certain that if I have one it should be minimal. The section in the MRAD RD is very thin but does have a lot of measurements. There are dots every .2mils and also dots at the .5mil increments between lines. For me it does interfere some in my ability to see splash. Less tree is desired. In testing, the reticle showed only the smallest deviation from correct dimensions. It starts a little larger than correct and then at about 8 mils crosses back to be very slightly smaller. At no point is it off more than .02 mils. That is to say, it is very good. The reticle is canted only very slightly relative to the adjustments, .03 mils in 10 mils of adjustment, in the counter-clockwise direction. This is also pretty good and of a small enough magnitude that it should not cause any problems.

Comparative Optical Evaluation:            

This review of the Meopta MeoPro Optika6 5-30×56 RD FFP is part of an ongoing series of sub $1k FFP mil/mil precision rifle scope reviews. These scopes are used as the optical comparison scopes for each other. In order of arrival, they are the:  Sightron SIIISS624x50LRFFP/MH, Athlon Ares BTR 4.5-27×50 FFP IR Mil, Athlon Midas TAC 6-24×50, Athlon Midas TAC 5-25×56, Sightron S-TAC 4-20x50FFPZSIRMH, and Nikon Black FX1000 6-24x50SF Matte IL FX-MRAD. For testing, these scopes were lined up together on a 5 slot adjustable v-block and evaluated using the procedure outlined in the methodology section at the end of this review. This same methodology is used on all long range scope evaluations and has been for several years now. Lastly, the Nikon had some issues necessitating its return. At the time of this review’s publication, its replacement has not arrived.

The Meopta MeoPro Optika6 5-30×56 RD FFP was optically the most interesting of all the Sub $1k ffp optics I have tested. The reason for this is that it was the most unpredictable with regards to how it would perform on any one specific attribute. For an example, we will start off with resolution. The Meopta was significantly better than all the other sub $1k scopes with regards to resolution. It was good enough I actually broke out a USO SN3 3.2-17×44 I was testing for my uncle to test it beside the Meopta just in case. That probably wasn’t necessary. The answer was no, the sub $1k Meopta Optika6 is not competitive with the USO that had been well over twice the price. It does, however, lead all other sub $1k scopes tested in resolution. On the flip side, it is by far the worst at handling stray light. It should have come with a sunshade. If you buy this scope, buy a sunshade and you will be a much happier person. This stray light issue was a pain for me as both my principle shooting range, and my optical comparison area are south facing and anytime any direct sunlight landed on that objective from any angle it significantly degraded performance. It actually took a while to figure out exactly what was going down as the stray light would sometimes show up as the typical hazy look, but other times things just looked out of focus or showed as very telltale blooms.

Resolution and stray light were what I would call the two bookends of the optical performance of this scope. Following that pattern, The Meopta’s depth of field was the best in the group but its eyebox was the worst. In practice, at the range, the eyebox was perfectly functional, I actually had mistakenly thought it would prove to be roomy when compared to others. However, shorn of the stabilizing adjustable cheek piece of my rifle, it proved the smallest. On field of view, the Meopta had one of the largest, but it also had close to the most pronounced barrel distortion. The Meopta again led the field with very minimal chromatic aberration but was only average when it came to contrast. Despite having one of the few larger 56mm objectives in the lineup, the Meopta was only average in low light performance. What to make of a scope so often at the extremes? I think a couple things are notable. First, though the Meopta did spend a lot of time at both the top and bottom of the lineup, it spent more at the top than the bottom. Second, it tended to land near the top on the most important aspects of performance, these being resolution and field of view. Its worst showing, easily stray light handling, is also easily remedied with a sunshade. So, on balance I would say it performs better than average optically for the price, provided you have a sunshade on it.

Mechanical Testing and Turret Discussion:

            First we will start by talking about the unique the Optika6 has. The elevation pulls up to adjust and pushes down to lock. Oddly, the windage is neither capped nor locking. The zero adjusts on both knobs with the removal of a single screw in the center of the elevation adjustment and then removal and repositioning of the outer sleeve.  Meopta has made this single screw easily removable without tools for the elevation knob which is nice. The windage knob’s requires a coin or screwdriver. The zero stop on the Optika6 scopes is a unique system. I have illustrated how to change it in the illustration below. You will note that, due to its unique cog-based system, use of the zero stop system will limit the maximum elevation range to a little less than three full revolutions. This comes out to somewhere around 28 mils total travel, which is a lot. You also may feel the zero stop cog as you rotate past it moving to your 2nd and 3rd revolutions. It feels sort of like a loose mechanical part. In fact, the first time I felt it I thought something felt loose and broken. Eventually, I realized what it was and that it is not an issue. Really, it is a pretty clever zero stop system and solves the difficulty that adding the locking mechanism to the elevation knob created for making a zero stop system.

Here is where I will talk about the feel of the clicks in the adjustments. Most people are just wrong about clicks. Everybody seems to say they like firm, stressed out, super positive clicks and not squishy ones. This really comes down to saying you want almost all the resistance to motion in the knob to come from the click detent itself and not something else, usually an o-ring. I used to think this might just be a matter of taste, but it is not. Most people are just wrong in their preferences, and here is why. This is not about the tactile sensation of handling your knob and wanting it firm and positive. This is about counting the clicks as you adjust, not miscounting, and not having to break position to look up and check that the knob is on the correct number. If the turrets are the very “clicky” variety, best characterized by the S&B MTC turrets, you will often experience clicks that you miss. This is because it takes a lot of force to move the turret over the first detent, but between the first and second it takes almost no force. So, your turning pretty hard and the turret skips though several detents quickly enough that you don’t feel them all. The Meopta Optika6 is not near as bad as the S&B MTC in this regard but I did experience some miscounted clicks on it and had to break position to look up at the knob on it. This is something you very easily note when you are assessing the tracking on a humbler device but might actually fail to notice in the field, leading you mistakenly attributing a missed shot to another cause. I mention all of this because people will like the feel of these turrets. They will say things like, ‘they feel very positive and adjust with a pleasing amount of force’. Perhaps Meopta has done them just right for the market. It certainly doesn’t pay to tell your customers they are wrong and people seem to like “clicky” feeling turrets. My thoughts are that I miscounted clicks on these very nice feeling turrets and I never miscount on nasty, squishy feeling ones.

Now on to the tracking. The first thing to note in the tracking of the Meopta is that there is some slop due to the locking turret design. Internally, there is some sort of spline sleeve that allows the outer part of the adjustment mechanism to raise and lower to lock and unlock whereas the inner portion contains the adjustment threading. In this design, the outer portion also contains the click detents. As such, it is the outer portion that you can both see and feel. You cannot see or feel that there is just a little movement in that spline sleeve joint. The effect of this is that there is about .07 mils of slop in the system. So you might adjust up 6.0 mils on the knob and have the reticle at 6.0 mils on target. Then, you reverse and go down to 5.9 mils on the knob but your reticle will be at 5.97, having moved only .03 mils because of the slop. So, whenever you are adjusting up, your adjustments will always read .07 mils higher than when you’re adjusting back. This is a bit annoying, mostly because it means that whenever you reverse direction for a shot adjustment, you get less magnitude of adjustment than you think. I understand this is a common behavior for locking turret designs. The windage, which does not lock, does not display this behavior.

Now for the tracking. Going up from optical zero, the scope tracked clean to 6.0 mils. At that point it starts to loose little by little. At 13.9 mils on the adjustments the scope has optically moved 14.0 mils. It adjusts a total of 15.7 mils up from optical zero. Of course, going back it is +.07 mils reticle position at each knob reading.

Going down from optical zero, the adjustments go to 18.0 mils. Going down they actually look good at that 10 mils but, of course, when you reverse and go back up, the .07 mil slop now makes it look like you’re a click off.

Overall, this means that the adjustments are quite well calibrated, notwithstanding the .07 mil of slop you have because of the locking turret. They are never off by more than .1 mil from what they read. The scope shows a 33.7 mils total elevation adjustment, but remember that the use of the zero stop will limit you to a maximum of about 28 mils.

Going left to right on the windage turret that does not have the locking feature, you notice no slop. It adjusts cleanly for the 4 mils each way I have on the target and has a total range of 17.0 mils right from center and 17.3 mils left.

Testing for lash in the parallax adjustment of scopes is not one of my regular procedures but I noticed it while shooting with this scope so I have fully investigated. For those who don’t know, lash in the parallax knob refers to when there is enough slop in linkage inside the scope that adjusts for parallax that it can noticeably shift position under recoil. Important to this is that the movement will only occur if you adjusted one way (typically coming up to your distance from minimum focus distance) and not the other (coming down to your distance from infinity focus distance.) This is because the slop basically represents the internals shifting from one side of their adjustment channel to the other. If they start on the side they would be shifting to, they have nowhere to go. On this Meopta, if you focus up from min distance to your range you will notice that after a number of rounds fired you have gone from zero reticle movement with head bob to about .06 mil of movement because the parallax has shifted a little. There is no shift if you adjusted from infinity down to your range.

To round out the mechanical testing of the Meopta, no reticle shift occurred with change in power, diopter adjustment, or parallax adjustment. So, all good on those tests. I would say there is a trend to all of the mechanical observations on the Meopta Optika6. That trend is that the mechanisms were all calibrated and working properly but there was a little bit of play in them. Realistically, this is not going to effect the use of the scope for long range shooting or hunting. You won’t fire enough rounds at the same range to move the parallax even if it was adjusted the direction that has a little slop. Similarly, the slop in the elevation adjustment due to the locking feature never causes things to be more than .1 mil off. The only way you will notice the slop in these adjustments is if you are testing it on a humbler apparatus such as I did or are shooting many rounds at the same distance.

Summary and Conclusion:

            At time of press the Meopta MeoPro Optika6 5-30×56 RD FFP is sitting at about $899 from the various online retailers. It is a very feature rich optic at that price, having illumination, a locking elevation turret (though, oddly, not windage) zero stop, and a detachable throw lever. On balance, it is the most feature rich optic tested in this sub $1k series. You can have it in a variety of reticle configurations, as well as with MOA instead of mil adjustments, but I think will be most popular in mil/mil with ILya’s MRAD RD reticle, which is a credit to the scope. This scope can also feature Meopta’s unique Dichro reticle technology but does not currently come with this technology in a reticle I would be interested in (a good mil one).

Optically, the Optika6 5-30×56 RD FFP is the least predictable performer in the lineup, as often landing best or worst in the test lineup than anywhere in between. On balance, it tends to do better on more important aspects of performance such as resolution and worse on less important ones such as barrel distortion. However, it really requires a sunshade in most conditions to function well and should have included one. I will note here that at the time of my writing, the sunshade for the 56mm Optika6 is not yet available and the 56mm MeoStar shade will not fit. In the end, I would say the Meopta Optika 6 performed above the average of its peers optically, but more in a Brett Favre way than a Peyton Manning one.

Mechanically, the Optika6 5-30×56 RD FFP can be best characterized as sound and properly calibrated but with some slop in the system. Both the elevation adjustment and the parallax adjustment have this slop, which essentially means they behave just slightly differently when adjusted one direction relative to when they are adjusted the other. In the case of the parallax that means it can show a little lash when adjusted from minimum focus distance to our target distance. In the case of the elevation knob you will note about a .07 mil difference at each increment depending on whether you adjusted up to that increment or down. The Meopta MeoPro Optika6 5-30×56 RD FFP really leaves its potential buyer with a lot to think about because so often it excels or lags in such dramatic ways. On balance, though, it excels more than it lags and I think that Meopta will find this first substantial incursion into scopes with precision long range features a rewarding one.
