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-1 Reticle

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:

https://www.swfa.com/swfa-ss-hd-3-9×42-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:

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:

https://www.quora.com/What-is-the-resolution-of-the-human-eye-in-megapixels

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.

I am kicking off another comparison since it sorta got my interest.  While I am not a target shooter, I have some peripheral interest in high magnification scopes and they are interesting from an optical standpoint.  For a little while now, if you really wanted a high mag scope and you had some money to spend, you got a March.  March seems to have been administering a (maybe well deserved) beating to Leupold and Nightforce despite their occasional attempts to fight back.

Some folks in Europe, however, are apparently using IORs a lot, which I find odd since my recent experience with IORs has not been great.  I live in the US, so for a lot of people here the IOR experience has been somewhat influenced by a rather colorful importer, so I will ignore IOR for now.

 

There is always S&B Field Target scopes and Kahles 10-50×56 Competition that looks to have been designed to compete against it.

I am, however, very interested in who can challenge March for less money, which led me to Delta Stryker HD 5-50×56, Vortex Golden Eagle 15-60×52 and Sightron SV 10-50×60.

In the future, I might expand this to other scopes, but now I am looking at these three.  Still, I am kinda curious about Leupold’s 7-42×56 VX-6.

Here is teh spec table for some of them, with the threes copes I have on hand right now in bold.  I will make a few videos on the subject with the first one below the spec table.

This is the type of scope I have a lot of interest in.

Thanks largely to Light Optics Works (LOW) being a pretty decent Japanese OEM, the quality of a long range scope you can get under $2k has really exploded in recent times.  It seemed like nearly every brand was getting something made by LOW.  Naturally, other OEMs started getting into the game and offering increasingly good product at competitive prices.  Now, I can get a full featured scope that is reasonably decent anywhere from $600 to $1700.  There are obvious differences within that price range and that is one of the things I am looking to explore.

In the past, SWFA had this segment largely to itself, thanks to the success of their 3-9×42 SS HD, 3-15×42 SS Classic and 5-20×50 SS HD.  Frankly, I still use these and the 3-9×42 is one of my all time favourite scopes due to its simplicity and ruggedness.  If you are looking for track record, it is hard to do better than these.  That having been said, the new players are more full featured designs with more modern reticles.  I fully expect SWFA to not take it lying down, but in the meantime, I figured I should make an overview of what is out there.  In the video below I talk a little bit about three of the contenders: Athlon Ares ETR 4.5-30×56, Vortex Viper PST Gen 2 5-25×50 and Delta Stryker HD 4.5-30×56.

I also have a lot of mileage with much less expensive, but very decent Athlon Ares BTR 4.5-27×50, so as I go through this review, I will talk about it as applicable.  A bit further down (below the video and some advertising) is the spec table where I show several additional scopes that I will add to the conversation a little later in follow-up videos.  Sig Tango6 4-24×50 and Vortex Razor AMG 6-24×50 are both designs I happen to like, albeit for different reasons.  I will talk more about them as I go down this path.

I am pretty open with the fact that I am Jewish and unlike majority of Jews in America, I have never voted for a left wing candidate and do not expect to any time soon.

I grew in the Soviet Union, so I have a very dim view of the left wingers’ paradise.  I grew up in one.

I want Jews to be armed and capable of preventing the next Holocaust.  I sure would have preferred if it did not take a massacre to get American Jews to open their eyes, but apparently they are hard to shake from their slumber.

I have built a good number of AR15s over the years both for myself and for others, so I have developed a healthy set of preferences.  Recently, someone asked me about the build for a very specific AR15 that I had in a picture, so I figured I should explain a little more why I built it the way I did.  In general, I have talked a little about basic component choices for ARs here.

Here is a picture of the specific build in question:


Before I get into the specifics, let me walk you through my reasoning for this build.

This is my take on a general purpose 5.56 AR-15.  It is not optimized for any one thing, but I want it to do everything an AR-15 carbine is supposed to do in a pinch, from CQB to long(ish) range engagement.  For a 5.56 long(ish) range is out to 600 yards or thereabouts.

What his means is the rifle has to be light enough for speed and balanced well enough for speed while still maintaining reasonable accuracy for longer distances.  What was also an important consideration for me was that the barrel maintains consistent POI even as it gets a little warm.  I put links with a bunch of components I like at the very bottom of this post, rather than embed links everywhere through the text, so if you want to see how much all these things cost, just scroll down.

For the barrel to be consistent, it should not be a pencil barrel.  I have seen plenty of ultralight barrels that are quite accurate, but they do warm up quickly, so I decided to go with a medium weight design.  This one is from AR-15 Performance.  They offer a good bang for the buck and I can buy their improved bolt already matched to the barrel.

They change the configurations they offer, so the specific barrel I used is no longer on their webpage.  Here is what it is:

-16″ length: I am OK loosing a little speed for maneuvaribilty

-Diameters: 0.8″ under the handguard, 0.75″ gas block, 0.718″ in front of the gas block.  Basically a simple mid-weight/SPR type profile

-5/8-24 barrel threading leaves a little more metal at the muzzle.  I do not know if this makes any difference, but I see no downside.  I use a 30cal muzzle device and it seems to work fine.  When I move to a free state and start buying suppressors a thread-on can for my 308 will also work on this barrel if need be
-Wylde chamber for best results with both 223 and 5.56 ammo.
-4150 Chrome Moly with melanite treatment all over the place.  Supposedly, it lasts longer than stainless, but I do not think I am in danger of shooting either one out any time soon.
-Mid-length gas system: I tend to go with the longest gas system I can get in a barrel.  Most carbine length gas systems I have seen appear grossly overgassed, so with those I prefer adjustable gas blocks.  With most mid-length gas system barrels I get proper gas volume with simple non-adjustable gas blocks.
AR15 Performance makes good barrels, but they are not the only game in town.  Given all the excellent options out there, I generally use AR barrels that are in the sub-$300 range and aside from ARP, I have been quite impressed with Faxon match barrels for the money, same fro Criterion Hybrid barrels.  It hatd to go wrong with either one of these.  For a little more money, Rainier Ultramatch is also very good (and a little prettier to look at).  Basically, for this type of a build any 16″ barrel with a diameter in the 0.75″ – 0.80″ is fine.

Speaking of gas blocks, this particular build has a simple set screw version that happened to fit this barrel very tightly.  Generally, I prefer clamp on gas blocks like those from Daniel Defense and a few others.
For ultimate precision or if the system is overgassed, there are many nice adjustable gas blocks out there, like those from Superlative Arms and a few others, but given a choice I use simple non-adjustable ones when I can.
The handguard is a carbon fiber weaver from Brigand Arms.  Since I do a lot of shooting off hand and I did not use an ultralight barrel, I wanted to use the lightest possible handguard to keep the balance point from moving forward too much.  Brigand handguards are the lightest available and very strong.  The only downside is that if you manage to stick your figner through the weave and touch a smoldering hot gas tube, you will not enjoy it.  Ask me how I know…
The bolt is from ARP, but the carriers I like are single piece ones from Voodoo.  You can either buy just the carrier or the entire BCG.  Aside from being one piece, they are also coated with something that makes them slick and easy to clean.  All my builds going forward will be using these.  They offer both standard and lightweight carriers.  Use standard weight with non-adjustable gas block.  If you are going with an adjustable gas block, go for the lightweight carrier.
The charging handle is an ambidextrous affair from Radian called the Raptor.  Being able to work the charging handle with either hand is important for me.
The upper receiver is a standard Aero Precision piece.  You can get exotic with these, but I usually do not.
The lower receiver is from VC Defense which gives me ambidextrous bolt release.  I often shoot with a sling, which keeps my support hand occupied.  After a mag change, being able to drop the bolt back with the shooting hand is useful.
LPK and trigger are from Geissele. It is SSA-E trigger in this case which is a very good option for general purpose use.
The stock is the Ultralight from Ace which uses a rifle extension.  This part is important since a rifle extension/buffer/spring seems to shoot notably softer than the carbine one.  It is also very light, which helps me keep the balance point right under the magwell.  This design also allows me to rotate the buttpad slightly which help with the precision side of things.
Spring and buffer are absolutely standard.
I live in California, so I have to use a finned grip, which is stupid, but must be done to comply with our crazy laws.
The ambidextrous safety, like the charging handle is from Radian Weapons and it has two modes: 90 deg and 45 deg.  I use a 45 degree set-up since that makes for a better thumbrest (California stinks).

I usually do not post info on various sales and things like that, but when I see a major discount on a product I recommend anyway, I figured it is worthwhile.

It looks like there is a major sale on Vortex Razor HD LH scopes with G4 BDC reticle that I helped design.  These are excellent hunting scopes and at current prices, they are an absolutely screaming deal.

3-15×42 for $550

2-10×40 for $500

1.5-8×32 for $500

I was busy trying to wrap up my article on 8x erector ratio low power scopes, when I got an e-mail from Geoff from Burris saying something along the lines of “we’ve got this whole Burris blog thing going, do you have any interest in writing a guest post on what to look for in a low powered optic?  In return we will say thank you and link back to your website”.  I asked what I can say and what I can’t if I agree to put something together and he came back with what effectively amounts to “you can say whatever you want, but I would really appreciate not getting fired over this”.

In general, I have to commend Burris folks like Geoff and Sky for still talking to me after all the crap I’ve given them over the years.  They are good people and I have a lot of appreciation for their ability to take criticism and use it to make better products (or it might simply be masochism; they are not fessing up to the details).


That having been said, I think Burris gets a few things wrong and a lot of things right with LPVOs (low power variable optics) being a category really get right.  That mostly goes for Steiner too, so I threw a couple of references in there for Steiner P4Xi, assuming that is not enough to get Geoff fired.

Here is a link to the Burris blog post in question.

I like ARs and I like sorta “general purpose” scopes.  In the past, a general purpose scope was something along the lines of a 3-9×42, since everyone always assumed that a “general purpose” scope meant a medium magnification variable on a hunting rifle.  I bet that ARs of all sorts are outselling traditional botl action hunting rifles by a good ratio right now, which is forcing a re-definition of what a general purpose scope really is.  As the available erector ratios go up, scopes like the the 1-8×24 and similar are becoming the new norm for general purpose use.  Still, they have their limitations and I am extremely curious how it is going to develop further.
