As I was ready to publish this, I noticed that Doug from CameralandNY just put this scope on sale for $849. If you call him and mention Dark Lord Of Optics, you will get an additional $50 gift certificate for anything else from Cameraland (rings, caps, etc). That brings the price of the P4Xi down to a hair under $800.

I have been looking at this scope for some time now and I found myself liking it a fair bit.  It is a little bit of an oddball design in a sense that finding something similarly configured to compare it to.  The only other 4-16×56 scopes I found are the much more expensive Hensoldt and S&B. Most of the 3-15x, 4-16x and 3-18x scopes out there use a smaller 50mm objective (kinda like Steiner’s own T5Xi 3-15×50).  Meopta Optika6 will have a 3-18×56 design, but that is not here yet. In the end, I ended up looking at the Steiner P4Xi next to a couple of higher magnification scopes I have on hand with 56mm objective lenses to get an idea of how it stacks up.

Here is my conclusion in a nutshell: if you can find this scope for around $1K you should pick one up.  At $1500, it would be a bit of a harder sell, but around a grand it is a superb option. It tracked true.  The turret feel is very good and optical quality is very respectable. It especially shined in low light. There is enough magnification to get me pretty far out and the reticle is very well suited for precision shooting where you dial for elevation and hold for wind.

Here is my customary comparison table which is not really useful in this case because of the unusual configuration.

Looking at the numbers, nothing really sticks out.  The scope is reasonably sized for the class and on the light weight side for a 56mm objective design.

There is plenty of internal elevation adjustment available, but the turret is a double turn design, wo you get 20 mrad with proper mounting.  I had it mounted in a Aadmount with 20 MOA incline built in. With that configuration I go the two full turns.

In practical terms, since I do not shoot ELR (yet), I do not need that much adjustment, so most of my testing was over the first 9 mrad.  I did not do a shooting test for the entirety of the 20 mrad adjustment, but I did test on a gun out to 16 mrad with very uneventful results.

The scope spent time on two guns: The Fix with a 24” Proof barrel chambered for 308 and large frame AR with Dracos 243Win barrel on it (below).  Neither is a kicker, but I have spent some time shooting off the bench, prone and sitting with both guns to see how forgiving the scope is. The eye relief is fairly long and quite flexible.  This scope is pretty easy to get behind. That is one of the advantages of a large objective. Even at 16x, the exit pupil is a rather generous 3.5mm

Another nice feature is that the elevation turret does not go up and down when you dial.  It always stays the same height and there is a window at the bottom of the turret that serves as a revolution counter: white for the first turn and green for the second turn.

The numbers engraved on the turret are color coded to match the turn indicator.  0 through 9 are white and 10 through 19 are green.

Side focus adjust the image from 50 yards on out to infinity and infinity is actually infinity.  I was able to focus on some trees a couple of miles out. Depth of field is fairly generous, but still, for shooting inside of 50 yards, lowering the magnification helped.  On 4x, I could shoot quite comfortably and accurately don to 20 yards or so. There was some parallax, but it was manageable.

Reticle illumination control is a rotary knob integrated into the side focus turret.  The illumination level is calibrated to be just about perfect for low light. Only a portion of the reticle is illuminated, making an illuminated “T”, of sorts.  In the picture below, I set illumination on a rather bright level, so that the camera could focus on something. It looks much sharper when you look through the scope.

In general, the SCR reticle that Burris and Steiner use across a wide variety of different scopes is quite thin and well suited for precision shooting.  I think it is a little too thin on 4x, especially as light goes down, but that is where reticle illumination really helps. Here is what the reticle looks like on 4x, 8x, 12x and 16x.

From top left: 16x, 12x, 8x and 4x

Optical quality was very good given the price.  When I compared it next to the Delta Stryker which costs a fair bit more, Delta was the better scope during the day, with better resolution and better CA control.  However, at night, they performed very similarly with Steiner having unusually good flare control for the price range. Compared to Ares ETR, P4Xi had a little more CA and little lower resolution, but the contrast on the Steiner was better.  In the middle of the day Athlon Ares ETR looked a little better, but as the light went down P4Xi was the better scope. Its reticle illumination is also much better in low light than that on Ares ETR.

I think you are beginning to see the drift of my take on the P4Xi at this point: it is easy to get behind, seems solid mechanically and optically and it really shines in low light.  Its only really notable optical flaw is some visible CA on high contrast targets, but I am kidna picking at it a little since there isn’t much else to complain about. It really reminds me of the original Steiner Military scopes a little in terms of the feel of the image.  So many modern designs try to squeeze huge magnification range into a scope ro make it super compact and generally that is a good thing. However, with optics, everything is a compromise. If you are not ready to drop $3k+ for a modern ultrashort, I suggest looking at something with a design that is a bit more on the conservative side of things and this Steiner is exactly that.  If you really want a 4-16×56 Hensoldt, but don’t have the budget for it, consider the P4Xi. No, it is not as good as the Hensoldt. It would be silly of me to claim it was, but it costs less than a third of the Hensoldt, stays zeroed, tracks true and is very good optically.

Harakiri, also known as seppuku, is a ritual suicide that used to be practiced by the samurai. Benchmade knife company, for whatever reason, decided to exercise the corporate version of it.

Apparently, they assisted Oregon PD in destroying some confiscated guns. I am sure that gun destruction was mandated by law and Oregon PD had no choice, but I am opposed to such idiocy in principle since a gun is a tool and I see no compelling reason to destroy one just because some moron used it in a crime. The gun, not being a person, does not bear responsibility for that.

Naturally, once that came out, someone looked into Benchmade’s political contributions and it turned out they were stupid enough to predominantly donate to anti second amendment candidates in the last few years.

Once the shitstorm started, they issued this official statement:


Benchmade is aware of the recent post from our local Oregon City Police Department.

We apologize for the confusion and concern that this post created. These were firearms that the Oregon City Police Department had to destroy in alignment with their policies. Oregon City Police requested the use of specialty equipment within the Benchmade facility to follow these requirements, and as a supporting partner of our local police force, we obliged the request.

Benchmade is a proud and unwavering supporter of both law enforcement and Second Amendment rights. These are commitments that we do not take lightly and will continue to support well into the future.

When asked for clarity from Oregon City Police Department, Chief Jim Band made the following statement: “When property is to be destroyed, it is the policy of the Oregon City Police Department to destroy property, including firearms, in accordance to our procedures and ORS. The Oregon City Police Department does not sell firearms.”

According a website opensecrets, here is how Benchmade has been donating to political candidates:

More details are available on opensecrets website linked above

Since I am a firm believer that stupidity should be punished by market forces, I will retire a bunch of Benchmade knoves I own and refrain from buying them for myself or recommending them to others.

When individuals donate to politicians I do not agree with, I could not care less. When a company does, that is like them saying: “we do not give a rat’s ass about those of our customers who disagree”.

In other words, I suspect that there is enough high-fiving at Spyderco, Kershaw, etc headquarters right now that their arms will be sore for a while.

Every year I tell myself that I will look at spotting scopes more since they are interesting and since it is easy for me to look at them: set up a few tripods on the deck and go for it. This year, I am actually going to do something about it.

One thing that is of interest to me is looking at different spotting scope types, which is exactly what I did in the video below.

65mm Vortex Razor HD is a conventional spotting scope, albeit with a new wide angle variable eyepiece (I also have the absolutely excellent fixed power eyepiece for it).

Athlon Cronus 7-42×60 is built more like a regular riflescope inside except without the need for moving the reticle and with short eye relief. US Optics used to have a spotter like this and Bushnell’s LMSS is a somewhat similar design. There is an optical compromise there: spotters of this type usually have a little worse image quality (multi-lens erector system instead of the prism), but they have an advantage in magnification range. In the case of the Cronus, I can use it handheld on lower powers or off a backpack or tripod as magnification goes up. These are also comparatively rugged inline systems, so the Cronus lives in the side pocket of my backpack and does not seem to be adversely affected in any way.

Meopta TGA 75 is another in-line design except it is does use an erecting prism. The interesting part about this one is the collapsible body. There aren’t a whole lot of these out there, but I am pretty impressed with this one, especially with the 30x eyepiece that has a reticle in it.

This is not really intended as a comparison, per se, since these are very different designs, but looking at them side-by-side is interesting as they work best for different applications. There is a lot of personal preference in selecting the right ergonomics. For example, modern wide angle eyepieces are excellent, but they bump my nose, so I have to look through the scope sideways, which induces strain. In other words, there is no replacement for actually using these things. A wide angle eyepiece may look great, but it gives me trouble for prolonged observation. Generally, for a lot of what I do, I really find myself drawn to fixed power eyepieces with longish eye relief. Meopta with a fixed power 30x eyepiece is a little limiting since it is a little wider than I like for scanning, but it has good FOV, so it works well for me. Vortex Razor HD with a fixed power eyepiece is just a joy to use, but 18x is a little on the low side for a spotter. A good 15x “Big Eyes” binocular will give you about the same image quality with less eye strain due to using two eyes and you need a tripod for either of these. The same eyepiece with the larger 85mm Razor is a 22x and you can get it with a reticle. That is a very nice setup.

In terms of sheer flexibility though, Cronus with its 7-42x magnification range is really difficult to beat.

One of the things I have been trying to ascertain last year, is how using a high magnification binocular compares to using a spotter. There is a tradeoff between magnification and using two eyes. What I found is that exit pupil still matters. I played around with a nice 20×56 binocular and some 15×56 ones and found that for reasonably relaxed viewing with big binoculars, I need more than 3mm of exit pupil. I can see more with a nice 15×56 binocular than with 18-20x spotter with 50-60mm objective, for example. However, Vortex 18x eyepiece with a 65mm spotter has some significant advantages in low light even with only one eye in use.

One approach I have not spent too much time looking into usign a doubler or tripler with a “Big Eyes” binocular. That could be an interesting “jack of all trades” approach.

Here is a spec table for the spotting scopes I discussed in the video above.

As 2018 draws to a close, I am in Hawaii with my family wrapping up with a few days of much needed vacation. In the past, every time I went on vacation, I had a camera bag with me. I am not a good photographer by any stretch of imagination, but I am definitely a camera geek and I have a fair amount of inside knowledge into the camera world having worked in it for a good number of years. I still maintain an interchangeable camera system (Micro-4/3) and also use an older Nikon DSLR that I pilfered from my brother. However, like most people these days, I take most of my pictures with a cell phone. This was the first vacation I have taken where I left my system camera at home. There are two reasons for that. One is that I have two fairly small children, so I have enough stuff to carry around. My enthusiasm for carrying an extra (camera) bag is a bit low. It is not like I can get the kids to pose anyway. Definitely not long enough to set-up a tripod. Another and probably more important reason is that my new Pixel 3 cell phone takes pretty remarkable pictures. Its built in HDR mode makes for stunning dynamic range. Night Sight mode does well in low light. Portrait mode does a decent job of blurring the background and a wide angle selfie camera on the front is responsive enough to capture my whole family. Primary camera is responsive enough to capture my kids when they are sitting still for a few microseconds.

Pixel 3 using Night Sight mode

Every time I take a picture, I get a very respectable JPEG and an HDR Raw that I can later dump into Skylum 3 (I just cancelled my Adobe Lightroom subscription) for some extra editing. Basically, as far as I am concerned, computational photography has arrived.

Do not get me wrong, the pictures I get from my Pixel 3 are not as good as the ones I was able to take with Leica Q (which I probably shouldn’t have sold), but they are good enough.

Now, I am fibbing a little. I sorta have an interchangeable lens system for my cell phone since I use Moment’s excellent add-on lenses.

Moment Amazon Page

I use a Moment case with telephoto lens fairly frequently, but I also have some mileage with their similarly excellent wide angle lens. Effectively that gives my phone camera an equivalent focal length of 18mm with tthe wide angle lens, native 28mm and 60mm with telephoto lens. However, since google started offering super-resolved digital zoom, I get pretty good performance at a good range of intermediary settings as well. Moment lenses are tiny, so I can shove them into my pocket and barely know they are there.

To re-iterate, if you are looking for ultimate image quality with seamless control of the depth of field and perspective, get a proper camera with proper set of lenses. Lugging all that stuff around will save you some money on weight lifting equipment. In my case, I do not need one for 90% of my photographic needs.

With that in mind, I figured I should examine the situations where I do still need to take a standalone camera with me. Of course, there will be situations where I will take a proper camera with simply because I like to take pictures

The first and most obvious is harsh environment use. We did some of that during this vacation and I did not prepare quite adequately for it. In retrospect, I should have bought a proper low light capable ruggedized and waterproof camera. Notice, I said “low light capable”. That limits the field considerably. There are plenty of waterproof and ruggedized cameras out there (like Olympus TG series) that are quite decent if you have enough light. If you need a camera for your ski vacation or to take pictures in a well lit pool, one of these will work fine. If you are more interested in video than stills, you can also consider various action cams like the latest GoPro. I gave one some serious thought, but my basic problem is handling. These are really designed to be mounted on something (helmet, bike, small gymbal) rather than be handheld. I have a camera with such a form factor (Z-Cam E1) and it is really not ideal for handheld use without some additional hardware that makes it a lot more expensive and quite a bit bulkier. However, it is a much large image sensor than any action cam and it takes the same interchangeable lenses I use with my regular Micro-4/3 camera. It was recently replaced with a much better Z-Cam E2 which is more than double the price. Neither of these cameras is easy to use, but if you are willing to put in some work, you can get good results.

During our stay in Hawaii, we went on a night snorkle to see manta rays. I do not own a proper underwater camera, so I bought an underwater housing for my DXO One camera. It has been discontinued, unfortunately, but it takes good pictures and uses a large-ish 1″ image sensor. The basic problem with using it underwater is that I can not change shooting modes, like switching between stills and video without opening the waterproof case. It gave me OK results and was much better than nothing, but I really missed having a proper camera.

That is something I will need to investigate a bit further, but unless you are willing to shove your system camera into a waterproof housing, your options are slim. There is the DC2000 from SeaLife which use the same sensor as my DXO One, but it seems to have focus issues. That leaves me looking at the two year old and very expensive Leica X-U. I have looked at it before and balked at the price, but now I wonder if I should just bite the bullet.

The X-U is a couple of years old now, but it takes good pictures and average looking videos. However, the lens on it is very sharp and it is good in low light. As far as price goes, if I get a waterproof case for one of my system cameras, the total price will get into Leica territory as well and the whole package will get a lot bigger. Another factor to consider is that Leica X-U is small enough and ruggedized enough to be use for general purpose outdoors photography where I would not be able to take a proper system camera with me, like skiing.

Another use case where I still need a standalone camera is anything requiring long reach. Once you get beyond 100mm equivalent, even with add-on lenses, a cell phone does not really do it any more. Perhaps that will be resolved in the future with some folded optics, but not quite yet and that is where I still use my Micro-4/3 camera with an inexpensive telephoto zoom and a F/1.8 prime where I need a little more reach in low light.

With all that, as I said, this was my first vacation without a dedicated camera and I really enjoyed the convenience.

If you have been following my random ramblings for any length of time, you will note that my preferred mode of operation is to pick a particular configuration and approximate price range and compare a good number of scopes that fit those two criteria side by side.

This is not going to be one of those.

The sorta undisputed king of the tactical hill in the 1-8x scope world in the last year or two was Minox ZP8.  March 1-8×24 with side focus has been out for a bit, but it seems to appeal to a somewhat different customer.  Last year, Nightforce released their 1-8×24 ATACR going largely after the same crowd.  S&B now also has their FFP/DFP 1-8x scope and I have a suspicion some other companies are going to join the fray.  I intend to gloss over this group almost entirely since I do not see myself spending in the neighborhood of $3k for a low power variable optic (LPVO).  Do not get me wrong, these are excellent design, but somehow it is easier for me to spend that kind of money on a long range precision scope and even that is getting to be a more difficult decision as mid-range stuff keeps getting better.  Now, as we get into the sub-$2k range, I sorta perk up.  I really want to be in the $1k range, but I am willing to pay a little more if it gets me a little more.  When I set out to put this article together, I wanted to explore this $1k to $2k range and since I was not able to get my hands on everything I wanted, I suspect I will revisit it again in 2019.

I saw the new March Shorty 1-8×24 at SHOT and thought it was an interesting idea.  The guys from March were adventurous enough to loan me one. I have a lot of mileage with their larger 1-8×24 that has side-focus, so the Shorty without the side-focus was really interesting to look at.  I am really impressed by March engineering, although there are some questionable decision there from product configuration standpoint (in other words I am very impressed with what the technical people at Deon accomplished, while being a little mystified by some marketing driven decisions).

Same for the GPOTAC 1-8×24 from German Precision Optics.  They really should know better than letting me loose on a new product, but I think that bravery will ultimately work out well for them.  I think they’ve got a good thing going there. As always, I have some things to complain about, but overall, it is a very solid scope.

Burris XTR II 1-8×24 has been my go to scope in this category since I can actually afford it, so I added it to the mix.

HiLux CMR8 is a lot less expensive, but I have it, so while it does not really belong in this group, it was interesting to see how it fits in.  I also had Hawke Frontier 1-6×24 on hand, so you will see it in some reticle pictures. It is a SFP scope, so it is an entirely different animal, but it is an exceptionally nice scope for the money and it was useful to have it as sort of a counterpoint: “if you do not need FFP, you can save some money” sort of thing.

Nightforce essentially told me to go F myself when I asked them for a loaner of the NX8.  That was unfortunate since it would have been interesting to test next to the March. Usually, a manufacturer tells me to take a hike if they are afraid of bad publicity, implying there is something wrong with the product. However, I am not aware of any major NX8 issues, and I did have a brief hands on with it on someone else’s gun. I will have to get my hands on one for a thorough review at some point via other means.

I am familiar with the Trijicon Accupower and PA Platinum, which is why you see them in the table below, but I did not have them on hand for this comparison.  With the PA, they have a new reticle I was impressed with coming out (Griffin Mil), so I will secure one when it is available. Accupower is not my favourite design, so I am not going to spend more time on it.

Looking at the specs, NX8 and March Shorty really stand out for their compact size and light weight, although GPOTAC is also pretty good with weight.  Other than March and CMR8, all the other scopes here are made in Japan, buy LOW. I am guessing the NX8 may have some US assembly in it. GPO adds the illumination module to their scopes in Germany.  March is made by Deon in Japan and CMR8 is a HiLux product made in their factory in China.

Right off hand, CMR8 is not as good optically as the rest of these.  It is pretty decent for the money though. I mostly added it in to show what you get for your money.  I will say that mechanically, CMR8 is working quite well including a stint on my 458 SOCOM that has killed a few scopes here and there.  Generally speaking, all of the scopes here were tested on a 5.56 chambered AR-15.

Before I talk about each individual design, I would like to spend some time on reticles.  I mounted the scopes on a tripod and took some pictures through them. The pictures are handheld with a cellphone, so they are not designed to tell you anything about image quality.  The church in the background is more than 700 yards away. They are all variations on “primary aiming point inside a circle” theme which I happen to like. CMR8 has a floating dot and a mrad grid inside a circle along with some choke style rangefinders around it.  The whole arrangement turned out a little busier than I would have liked, but I like it conceptually and if I had a chance to re-design it, I’d keep the grid, but make it thinner.

March has two concentric circles (they also have another reticle that has only one circle) and an aiming crosshair inside the smaller circle along with the a mil-scale outside it.  For some inexplicable reason, the lines in the primary aiming crosshair are quite thick. I am guessing it has something to do with how they illuminate it, but in practice, I would have preferred a small floating crosshair or a dot inside the circle (the scope I used had FMC-2 reticle; their FMC1 has liens that are twice thinner, so the reticle I would want is a combination of the two: FMC-2 circles with FMC-1 crosshair).  One of the reasons to get a LPV scope that goes up to 8x is to extend the engagement distance a bit, so a smallish primary aiming point is a good idea. Basically, you want the circle for speed and the dot or crosshair for precision. The reticle in the GPO hets the precision part right, but the circle is fairly small (it is a little hard to see in the 8x picture below, but in real life it is nicely visible at higher mags). GPO’s illumination is continuously variable, so it is excellent in low light.  On the scope I had it did not get very bright (I played with a prototype illumination module that did not get as bright as production models).  XTR II reticle is very well done in terms of line thicknesses and is the only design here that has a BDC reticle inside a circle. I would prefer a mrad-based design, but it works well enough (as I said this is sort of my reference standard in this category in terms of bang for the buck).

Here is what they look like side by side.  With CMR8, the larger circle is outside the FOV at 8x which I like.  With March, I think the two circles inside the FOV at 8x is a bit much, but the reticle is quick to use and very visible without without illumination.  Other than the thickness of the center crosshair, I really like this reticle. Also note the tapered bars that really help as you go down in magnification.  

The next picture below shows the same four scopes at 4x, 5x and 6x.  I am also showing the reticle of the SFP Hawke Frontier for comparison.  On the CMR8, the large outer circle gets into the FOV and blocks quite a bit of it.  With March, the tapered bars start looking more prominent, but the dual circle center arrangement looks to be about the right size for quick target engagement.  GPOTAC reticle again looks thinner in the picture than it really is, but in general, as you go down in magnification, it has to rely more on illumination than the other scopes here. XTR II’s 10 mrad circle remains a really good compromise between precision and speed.

As you go further down in magnification, the GPO scope becomes harder to use without illumination. I talked to them about it and the basically said that the 1-8x is more of a general purpose design, while the 1-6x is going to be a little more optimized for speed and AR use with a bolder reticle.  Honestly, I think they should add some other reticle options to the 1-8x, but even with the pre-production illumination module it worked pretty well for me in anything but the brightest light, so I am not going to complain too much. WIth March, as you get to 1x you begin to really see why those tapered bars are there.  Wisely, the guys at March kept the bars from going all the way to the edge on 1x. That leaves the aiming structure floating in the center and it really works well. With CMR8, that big outer circle keep the reticle visible, but I still think it is thicker than it should be.  Also, keep in mind that the XTR II reticle is perfectly usable without illumination on 1x; much more so than the picture indicates.

Now, let’s talk a little about how these scopes compare in other ways.  First of all, I have not spent a whole lot of time checking tracking. I did some minimal elevation tracking checks and they all seemed to do fine.  Generally, with scopes of this type, I prefer to not mess with the turrets, so I want them either covered or locking, which all of these were, except for March.  The Shorty came with March’s excellent low profile tactical knobs. These are some of my favourite turrets, but I think they are a little out of place on this scope. I would feel more secure with a covered design. I brought this up with my March contact, but he disagreed and said that he has never heard of their turrets being bumped.  Personally, I think March marketing people needs to spend more time with 3-Gunners and other AR people. That would give them a better grasp of this side of the market.

All of the scopes here stayed zeroed once zeroed and I really have no complaints about the quality and feel of the physical controls.  Subjectively, March has the crispest feel to the mechanics here, but I have always liked how March does the mechanics, so there is no surprise there.

In terms of optical quality, this ended up being a bit of a tricky comparison because of parallax and depth of field.  First of all, the CMR8 is clearly the weakest product here, but also the least expensive. The guys at HiLux said that they are working on fixing some of the distortion, so it should get better and at the time of this writing, it probably is (I need to check).  Most of the side by side was done with the Burris, GPO and March.

Before I talk about optics, note how short the March is.  It is difficult to make very short optics and the complaints I have about March’s optical system are a direct consequence of making it very short.

As an optical system, overall, I probably like GPO the most in this group.  However, if you stay in the 75-200 yard range, March has better resolution at a similar contrast.  Between 200 and 400 yards, the optical performance of the three scopes is pretty close. Once you get beyond 400 yards, the Shorty falls a bit behind the other designs here.  At closer distances, the Shorty also suffers if you stay at 8x, but dialing down magnification really helps and at closer distance with scopes like these, I always dial down anyway.  Basically, if I never shoot beyond 350-400 yards, Shorty is the better optical design. However, if I never extend the distance, I might as well save some money and get a 1-6x. All three of these scopes have fixed parallax at 100 yards or so.  Because it is so short, the March Shorty has really shallow depth of field, so it loses some resolution at longer distances as you get further away from its optimal focus. For the same reason, it seemed to pick up parallax error faster than the other two.  Significantly faster. At longer distances, both Burris and GPO were a lot friendlier. Interestingly, while XTR II and GPOTAC are both made by LOW and are likely related designs, GPOTAC had better DOF (depth of field) and less prominent parallax error at longer distances.  Still, XTR II acquitted itself rather well.

Flare was not very prominent with any of theses, although March had a bit more of it than the other two.  It comes with a sunshade that really helped, but it does make the scope longer (picture a bit further down).

With scopes that go down to 1X, the ease of getting behind the scope and a wide flat FOV (Field Of View) are really important and all three of these are quite good.  March has just a touch more distortion than Burris (and GPO is slightly better still) toward the edges as you move your eye laterally behind the eyepiece, but it is very reasonable.  I spent a fair amount of my time with these scopes shooting off hand and shooting quickly. I can see the differences between when I carefully look for them, but in practical terms there wasn’t enough to worry about or make a difference.  Whatever difference was there likely was driven by reticle variations more than anything else.

GPOTAC 1-8×24

Overall, I am pretty impressed with this scope, except, as previously mentioned, with reticle visibility at 1x.  I would have liked to see some tapered lines and thicker horseshoe or something similar that would make the reticle stand out more at 1x.  Also, since the scope I looked at is a prototype of some sort with illumination that is not as bright as on production models, I should probably revisit it with a full production illumination module some time.

It is really a very good general purpose 1-8x design and its only real weakness is performance on 1x in bright light which is reticle related.  Most scopes of this type have discreet illumination steps. GPOTAC illumination module is continuously variable, which I like a fair bit. In low light, it can be set extremely low, so it does not disturb night adapted eyes.  

Another thing I liked was that it was really easy to get behind (same as the XTR II).  Eye relief was quite flexible and parallax stayed in check very nicely out to 600 yards which was the extent of how far I took it.

I do not fully understand the need for exposed turrets on a scope of this type, but since they lock in place, I do not have a problem with it.

All in all, GPO 1-8×24 is a pretty good fit for a lot of applications, but for going fast with an AR, there are better reticles out there.  Outside of that, I really like this one, although for an AR-15, I do not think I’d be willing to dish out extra $500 for this scope over the optomechanically similar Burris XTR II.

In terms of direct competition price wise, GPOTAC goes head to head against the very popular Nightforce NX8.  That is some tough competition. While I am not a Nightforce groupie (there are some Nightforce groupies on every internet forum confidently stating that the reticles of the NX8 is woven from unicorn hair and illuminated by little elves living inside the tube among other nonsense) by any means, NX8 looks impressive on paper being nearly as compact as the March and equipped with extremely bright reticle illumination.  The little time I spent with the NX8 suggests that it is a better scope than the GPOTAC on 1x, while GPOTAC seems to be better at 8x. Reticles are in the eye of the beholder. One thing I dislike immensely about the NX8 is the exposed elevation turret. Interestingly, for some inconceivable reason they offer a version with covered turrets, but for LE/Mil only. Still, it costs the same as GPOTAC and is enjoying immense popularity.


March Shorty 1-8×24

As I mentioned earlier, from a technical standpoint, I really like what March has accomplished here and, if you are staying inside of 400 yards, this is an excellent option.  The things I take issue with are primarily related to the decisions made by product planners, not by engineering. As a general disclaimer, I took all of my concerns to March before publishing them and while they got a little defensive, they were fairly mature about it.  That’s a good thing. I’ve seen people really get their panties in wad after much milder criticism.

Most of my criticism has already been mentioned, so I am not going to rehash it too much: depth of field is shallow and the turrets should be locked or covered.  Reticles are in the eye of the beholder.

Interestingly, I really liked this scope as a 1-6x.  As a general purpose design, March’s larger 1-8×24 with side focus is a far superior option since adjustable parallax takes care of the bulk of my concerns.  

Also, with March scopes, reticle illumination control is a large rubberized button inside the parallax turret. With the Shorty, they use essentially the same turret housing, except it does not rotate since parallax is not adjustable.  However, on a tactical scope, a large rubberized pushbutton is not an optimal solution since it is really easy to press accidentally. In addition, March has two illumination modules: Hi and Low. Each has four brightness settings.  I have used both and the low module works well in low light, but is not nearly bright enough for anything else. The Hi module is too bright for low light, while still not being bright enough for daylight. It is just right for the dusk.  All twenty minutes for it. The saving grace here is that March has a third illumination module that they never talk about for some reason. It is a six position module where the rubberized button is just ON/OFF and there is a rotary lever that lets you choose between six settings.  This module has a lot more dynamic range and March should really be shipping the Shorty with it. You can probably request it in this configuration if you are so inclined.

When I summarized my take on the Shorty for the guys at March, it became apparent that while we agree it is a niche product, we disagree on what that niche is.  I am perhaps criticizing the Shorty a bit too unfairly, but I think I have to make clear that with all my reticle and DOF complaints, if I could get it with covered or locking turrets, I would have bought the Shorty on the spot with either of the two available reticle (FMC-1 which I slightly prefer is on the left) and with the six position illumination module as pictured below.

FMC-2 Reticle

March 6 position illumination module


Overall, the scope’s strengths really outweigh its limitations and the only thing that is a real deal breaker for me is the exposed non-locking turret.  I know how to deal with the rest of it and I can think of many applications for this design.


That having been said, while I do not think they will listen to me, I would really love to see what March engineers could do if they were tasked with making and ultra compact and light weight 1-6x or 1-5x design.  For an ultra light AR carbine with a good barrel, I would comfortably sacrifice a little bit of top end magnification for better DOF, light weight and compactness.

I also like the mounting solution: a single wide ring which makes positioning the scope on the rail very easy.  The scope March sent me had the sunshade, covers and cat tail included. I am not sure how it is configured for retail, but if I were to choose the right configuration, I would leave the sunshade in the box and keep the scope short.  The more time I spent shooting with the scope the more I appreciated its strengths and ignored the weakness, although I did stay inside of 400 yards for the most part.


Burris XTR II

I have already written about this scope in a different article, so I am not going to say too much here.  In the field of 1-8x FFP scopes, this is sort of a “goldilocks” product. It is well priced, very robust, optically good, and comes with a very serviceable reticle.  It is my go to scope for an accurate AR-15 carbine that I want to use across the course for everything that the 5.56 cartridge is capable of this side from varmint shooting.  It is $500 less expensive than GPOTAC and $800 less expensive than the Shorty, while giving up very little in performance. At some point, I will get it side by side with the Nightforce NX8 to see if the compact size and nuclear bright illumination of the NX8 are sufficient to make me pay the extra money it requires.  Maybe there will be something else announced at SHOT that peaks my interest. Until then, the XTR II sits on my AR.  The most direct competition for the XTR II comes from Primary Arms Platinum which is likely the same basic scope with a more mall ninja friendly reticle.  However, PA does have a mrad based version out and a better Griffin Mil reticle is coming out too.  I look forward to testing it side by side with the Burris.

Black Friday has always been a good time of the year to visit SWFA website (or stop by if you are local to them).  This year is no different.  They always have really significant discounts on their SS products and while I am not in the market for any (I already have more scopes than I know what to do with), I glanced and one really stood out to me.

They have 25% off on their excellent FFP 3-9×42.  I have two of these and they absolutely rock:×42-tactical-30mm-riflescope.html

I buy and sell scopes all the time and yet these two will some day be pried from cold dead hands, so to speak.

Here is a link to the whole Black Friday listing for SWFA, just in case:,3SY8,1CSKB7,EINB,1

I wrote a little while back in my interest in Straight Jacket barrels made by Dracos.  They are pretty expensive, which has kept me from trying them for some time.

For this Black Friday, they are giving a crazy discount on their AR-10 barrels in 243Win, 260Rem and 7-08.  $250 for a new barrel and $150 for a blemished (cosmetic).  Normally, these are $850 and $510 respectively.  If you are a reloader and want to try one of these barrels, this is an awesome opportunity.

I am getting ready to do a video on resolution as it pertains to riflescopes and I stumbled onto this nice tidbit from quora:

While I think of a good way to explain this, consider a concept of “acuity vs superacuity”.  It is directly relevant to observation devices and riflescopes.  Human eye acuity is roughly equivalent  to 3000×3000 pixels seen on a 19″ screen, two feet from your eye, while superacuity bumps it up to 18000×18000.

Let that sink in, while I plan a video on the subject.
