Visiting Primary Arms

Primary Arms visit turned out to be quite surprising. I have been talking to the gentleman who runs PA on and off for a while now, but somehow I still wasn't grasping the entire scale of their operation. Now, to be fair, I am certainly still not aware of everything they do. However, looking back on it, I really shouldn't have been that surprised. They have a seriously substantial warehouse since they stock they stuff they sell and, looking at their website, it should have been apparent that requires space and manpower.

What I didn't know is that they have a pretty solid engineering group in-house and how much effort and resources go into the Primary Arms branded optics. When PA optics line started, what they had were just comparatively standard OEM scopes that stood out because of the ACSS reticles. As I have elaborated previously, some ACSS reticles I like and some I do not. A lot of it is just personal preference, to be honest, and some is just stylistically differences. However, all of the ACSS reticles I have seen to date are intelligently conceived and I can clearly see what the design goals were and how they went about achieving them. That's more than I can say about most reticles out there.

PA optics line still has the various ACSS reticles, but there is a lot more to them now which is how they ended up within my field of view, so to speak.
Many of their products stopped looking like "me too" designs with good reticles. The line of micro-prisms that I have been talking about is unique to them. Other small prismatics out there come from different OEMs.

The new PLxC 1-8x24 LPVO is just exceptional and easily clears the bar to make it onto my list of recommendations (with room to spare, frankly). Optomechanically, it is clearly going after scopes like Razor Gen3 and ATACR. Given the price, if they ever add a diffractive reticle to it, they will absolutely be in the same conversation.

The interesting part is that when I first saw that scope, it absolutely threw me for a loop. At this stage in the game, when I look at a scope, I can usually make a pretty good guess which OEM it is from, especially which Japanese OEM. This scope sorta looked like a LOW design, except I had never seen that exact version (and for a good reason since it turned out to be entirely new and likely proprietary to PA). The turrets, however, did not look like it and did not feel like it. Click feel was different and when I took the removable part off, the insides were kinda sealed. I generally do not take scopes apart beyond what is expected of a consumer (sort of a courtesy to the manufacturers; although there are exceptions to that), so I did not go further.

Now, that I got a chance to spend a little time with the team at PA, it all makes sense. There is a good size engineering group in-house and an increasing number of the PA optics have some elements of their own design, with turrets being at the top of the list. There are other things coming though. For example, they are a bit cagey about what is happening there, but they are building a cleanroom. You do not need a cleanroom like that for QC.

Now, one of the things I look for when I visit companies is the quality of the team. If you have a cohesive team, a couple of smart engineers and company support you can get a lot of stuff done. The gentleman who is in charge of engineering at PA looked strangely familiar. It turned out that we had crossed paths in the past (through my dayjob) a decade or so ago. More importantly, we have some mutual friends who speak highly of his abilities. That's the kind of stuff I pay attention to and that also explains why I am seeing increasingly sophisticated opto-mechanical designs coming out of PA, with more on the way. Also, I got a glimpse into the insides of one of his turrets designs (looking at the CAD screen over his shoulder) and it is a clever system that should be durable.

For another example, PA has a few red dot sights in different price ranges and the new one I got to play with is the SR-10. It is a part of their SLx line, so it is on the budget end of things. We'll see how it does, but offhand, it looks like a pretty straightforward Docter-pattern open emitter red dot sight for use on both pistols and long guns. However, for a couple of hundred bucks, it comes with a picatinny mount and a very slim Glock MOS adapter. I'll confirm, but I am pretty sure it will sit low enough to co-witness with standard Glock sights. Decent collimation quality with a 3MOA dot.

The product line I have been paying most attention to lately was probably GLx. Don't get me wrong, the new PLxC seems good enough to satisfy even my optics snobbery and the SLx are very good budget options (admittedly, I am mostly familiar with SLx red dots and micro-prisms). GLx, however, might be the best bang for the buck of the bunch, starting with the 2x prismatic I looked at a little while back. Then, I looked at the 2.5-10x44 that is very feature rich and just excellent mechanically (it also has their own turret design and, now that I met the engineering team, I understand why it is excellent). Optically, it is better than adequate, but not exceptional. It is good enough for me to recommend it overall, though. I knew they had new GLx scopes coming, and that is what I really wanted to see while I was there. They were refreshingly open about their upcoming products. A couple of them they asked me to not talk about yet, but there are several that are coming soon enough to discuss. There were four new variable scopes I saw. One was the 1-10x24 FFP LPVO made in Japan by JOL. Three were made in the Philippines, all with FFP reticles: 1-6x24, 3-18x44 and 4.5-27x56. I got a chance to see near-production quality prototypes of all four and I was, honestly, pretty impressed.

General disclaimer: there isn't all that much I can immediately say from looking at scope indoors, but there are a few things to look for and I did not see any glaring problems. Mechanically, everything had a good feel and all had PA's own turrets that I noted earlier. I am not entirely sure what the final pricing will be and I suspect they are still finalizing that. Once I know the specifics, I'll let you know.

The 1-10x24 is a bit on the heavy side of the LPVO world, but I have seen this optical system before and it really is quite good with a well designed eyepiece, so it is easy to get behind. It should play nicely against other LPVOs out there that are used in a DMR-ish role, i.e. on accurate AR carbines that have to work from up-close and personal out to a few hundred yards.

The 1-6x24 was completely new to me. I had no idea it was in the works. Of the two LPVOs, this one is probably the one I am more curious about since I have not seen that optical system before. It did look quite respectable. Reticle illumination seemed adequately bright, but I was indoors the whole time. That's something to check. The eyepiece, however, is done very well, so I expect it to be quite easy to get behind. We had a long warehouse to use, so I set the scopes up on a tripod and spent some time peering through them on different magnifications. The 1-6x24 had good detail and good flare control best I could tell.

The scope I was arguably most impressed with was the 3-18x44. It has the same excellent zero-lock and zero-stop turrets I liked on the 2.5-10x44, but a better magnification range for crossover use and likely better image quality. With this one, we are getting into magnification ranges where there isn't a ton I can really say indoors, but it looked promising. This scope should be a contender as a crossover scope for anything from accurate ARs to lightweight precision rifles. I'll post full specs once available.

Same goes for the 4.5-27x56 model. It appeared to have more or less the same mechanical features, so I have reasonable confidence it will work well. I did not see anything obviously wrong optically, so that is encouraging too.

All of these GLx scopes showed some commonality of mechanical design and eyepiece design, which is a good thing. GLx scopes seem to sit in that rough sweetspot where you can get a lot for your money, but these are not cheap scopes. That's roughly the same market where Vortex' PST Gen2 plays. Various Athlon Ares scopes are in there as well as several others. This is where you can find decent quality Japanese scopes and higher end Phillipine-made and Chinese designs. This is really where the battle of the OEMs is happening right now, I think.

Lastly, I wanted to look at how they do QC and it turns out that every PA branded optics that comes in, no matter how expensive, is looked at. Every single one is taken out of the box and checked. That, I did not expect. To the best of my knowledge, for the inexpensive chinese optics, noone else checks every single one. With higher end products that is pretty common, but checking EVERYTHING is pretty unusual.

Overall, it was an interesting visit. PA is located in the part of the country I visit with reasonable regularity, so I'll make it a point to check on them every once in a while. I kinda want to know what they plan to do with that cleanroom.

Tikka and Anarchy Outdoors

Whenever someone tells me what should be their first boltgun, whether centerfire or rimfire, 90% of the time I recommend a Tikka of some sort.  To be blunt, Tikka is arguably the safest bet you can make these days in the rifle world in terms of bang for the buck.  They are not cheap, but they are affordable.  A few weeks ago, I was chatting with a friend of mine who works for one of the riflescope companies and happens to be a seriously capable precision shooter.  We spent a few minutes going through our memory banks and neither one of us could think of the last time we saw a Tikka boltgun that did not shoot.  Now, there are fancier guns out there, fancier stocks, high quality barrels, etc.  They all cost more money and as far as pure accuracy goes, Tikkas just shoot and you have to be a very capable shot to require something better than what most modern Tikkas seem to offer.
Still, some mild accessorizing does make them easier to set up and shoot. A reasonable starting point there is ...

Burris XTR Pro 5.5-30x56 Wrap-up

As we wrap up with the year, I am trying to wrap up with as many ongoing projects as I can. One of them has been the wrap up with the Burris XTR Pro 5.5-30x56. I have talked about the scope quite a lot during the past year. It is among my recommendations. It is also one of my selected reference standard designs. https://darklordofoptics.locals.com/post/5913627/reference-standard-2024-mid-year-re-visit
One of the questions about the XTR Pro that keeps coming up is which reticle is a better choice: SCR 2 Mil or SCR 2 1/4 Mil.
https://alnk.to/hswhBZO
I had the latter, so I picked up the former to be able to compare. It was also a way to check if the scope Burris sent is cherry picked. It does not look like it. The two scopes perform extremely similarly.
The choice between the two reticles really comes down to personal preference. I can see how some competition shooters would find the 1/4 Mil reticle a little quicker. On the other hand, the SCR 2 Mil works a little more naturally for ...

S&B 3-18x42 META

I've talked about S&B's META many times, but never really did a final wrap-up. Well, here we are.
It is a part of a new generation of 6x erector S&B scopes. It is a very solid scope in terms of fundamentals and I hope they do more with this basic design moving forward.

Factory Hornady 338 ARC 307gr Sub-X vs 300 Blackout 208gr A-Max Ballistics

Hi Ilya,

My distance spec for high confidence varmint/pig with a subsonic AR SBR is 300 yards. I was curious about the new Hornady subsonic 338 ARC down range ballistics at 300 yards, so I visited the Hornady website and did a quick comparison vs the Hornady subsonic 300 Blackout cartridges. This simple comparison follows below.

It would be very interesting to hear about how the down range ballistic performance (accuracy, wind drift and terminal energy) of the best subsonic 6.8 Blackout ammo you have used (or know of) compares to the results below.

The only subsonic Hornady 338 ARC cartridge available at this time seems to use the Sub-X bullet. The subsonic Hornady 300 Blackout cartridge options include the A-Max and the Sub-X. I chose the 300 BO A-Max for the comparison due to it's superior ballistics compared to the Sub-X line. The Sub-X to Sub-X comparison would be obvious, the heavier 338 with slightly better BC and similar...

December 11, 2024

I need some help leaning to shoot an AR with a scope and from a bipod. Not exactly scope related, so I hope this isn't too far from the routine here. The bottom line is that I know how to shoot from a sling, and in doing so my rifle / scope bounces and settles back to where it was when I broke the shot. I expect the same thing to happen when I shoot from a bipod but noooo waaaaay. The rifle bounces in every direction. I know I should be able to spot my shots, so I know what to expect (shooting .223). Anything helps. Should I try to find a low position or hold my chest off the ground? Do I squeeze the rifle into my shoulder or hold it of? Grip pressure? Low mounts and A2 stock? Magpul PRS stock? Pros and Cons of Harris vs. Magpul bipod? Should I ditch the bipod and shoot from a bag?

Edit: I think my real issue is that I am used to a solid cheek weld with the sling. I mash my cheek to the stock and touch my nose to the charging handle, which isn't possible with precision style equipment....

Happy Thanksgiving, Y'all!
from ChatGPT, Grok and Yours Truly

Every Thanksgiving these last few years I wake up in the morning knowing that this is the year when I will finally get in touch with my sweet, emotional and well meaning inner self and write a truly profoundly heartfelt and warm Happy Thanksgiving message.

That results in several minutes of hopeful soul searching.  Sadly, no matter how deeply I dig, all I come up with is sarcasm, cynicism and a profoundly dark sense of humor.

This year, I decided that I have been looking for humanity in the wrong place and that the advent of AI might offer some ability to fake warmness and optimism for people like me.  

I asked ChatGPT and Grok the same exact question: "write a profound happy thanksgiving message for a bunch of patriotic gun nuts"

Here is what I got back:

 

From ChatGPT:

Happy Thanksgiving to Our Fellow Patriots!

As we gather this Thanksgiving, let us give thanks for the blessings of freedom, family, and the great land we call home. We honor the principles that built this nation—strength, resilience, and an unwavering commitment to liberty.

Today, as we carve the turkey and reflect on our blessings, let’s not forget those who have fought to protect our freedoms and those who stand ready to defend them still. It's a time to cherish the bonds of family, the camaraderie of friends, and the power of unity that keeps our American spirit alive.

May your Thanksgiving be filled with the warmth of loved ones, the satisfaction of great food, and maybe a few moments at the range to remind us of the rights and traditions we hold dear.

Here’s to faith in the future, pride in our past, and love for this great nation. From our family to yours—Happy Thanksgiving, and God bless America! 🦃🇺🇸🔫

 

From Grok:

Happy Thanksgiving, fellow patriots and guardians of freedom! On this day of gratitude, let's give thanks for the liberties we cherish, secured by the vigilance and resolve symbolized by each of your steadfast arms. May your gatherings be filled with the warmth of camaraderie, the echoes of liberty, and the assurance that the spirit of America is alive in every one of you. Here's to the Second Amendment, to our shared heritage, and to the unyielding spirit of independence. Enjoy your feast, your fellowship, and keep the flame of freedom burning bright. Happy Thanksgiving!

 

Please put in the commens below which AI message you prefer before reading further.

 

ChatGPT's message conviniently ignores the "partiotic gun nut" part aside from the a few moments at the range reference.  Generally, it reads like something put together by script writers for "white dudes for Harris" commercial upon realizing that they have to find employment in a post 2024 election world.  It is not the power of unity that keeps our American spirit alive.  It is the American spirit and the American idea that give us some measure of unity, not the other way around.

 

Grok's message is more on point.  It actually mentions the 2nd Amendment and "assurance that the spirit of America is alive in every one of you" is both conceptually more accurate and somewhat flattering.  

 

I mostly use AI for technical stuff where it can do the calculations for me or write a few lines of code faster than I can.  However, it is full of bovine manure abotu 20% of the time, so I would not use it for anything technical where I can not easily check what it has done and find mistakes.

 

All that aside, Happy Thanksgiving, Gentlemen!

Vortex Defender XL
Taking a first, rather extensive, look.

When I visited Vortex back in September, I mentioned that I took a quick look at their new line of Defender red dot sights.


While all three are pretty nice, I thought the largest variant, the XL, stood out.  Despite being relatively compact and having a substantially large window, it seemed to maintain collimation quality very well pretty close to the edges.  That was noteworthy.

Now, I have done a good amount of shooting with it and have some initial thoughts.

The main reason I went with the XL version is two fold.  One is that it looked to have a very large sweetspot.  Another is that while the overall trend with pistol mounted red dot sights is toward enclosed emitter designs, one of the areas where open emitter sights have a distinct advantage is window size.  If you try to make an enclosed emitter RDS with a window this big, it will no longer be practical on a pistol.  Too big.

One of the long running experiments I have going on is an attempt to figure out how much of an issue (for me) is window size.  Many people want the largest window possible.  Others do not hugely care.  In principle, with a larger window size, your follow-up shot can be faster if you enver lost sight of the dot due to the recoil impulse.

In practice, I tend to shoot with rather slim and compact handguns a lot (Glock 43x or 48 most commonly), where the gun moves enough to always lose the dot.  Since you always ahve to reacquire it, the larger window size does not seem to offer all THAT much of an advantage.

Now, I have three similarly sized Glocks (two GLock17 and one 34) with different size red dot sights: Vortex Defender XL, Shield RMS2 and Leupold Deltapoint Micro.  I am going to do some experimentation and see how quickly the gun settles back on target for me with all three.  

The Defender XL is somewhat new for me, so before I do anything with a shot timer, I am just making sure I do some practice with it.

There are several reasons, other than the large window that made me the XL version of the Defender intersting.  I wanted to see if the size will prove to be a hindrance for carry.  I also really liked how they did the battery compartment.  It also comes with the largest dot size of the three: 8MOA.

There are three models: XL, ST and CCW.  XL and ST use DPP footprint.  CCW uses RMS/RMSc footprint.  Parallax and distortion seemed very well corrected on all three.

The window size of the XL is 25.5x23.5mm (WxH). On the ST it is 23x20mm.  On the CCW it is 20x16mm 

In practical terms, the width of the window on the XL is about the same (very slightly narrower)as the width of a full size Glock slide.

The housing, naturally, extends a little bit wider with the widest point being the brightness control buttons on the left and the right.  That makes them very easy to find via the tactile feel.  It also makes me wonder if I will accidentally press them when carrying the gun, so that is something to experiment with.  I do not have any issue concealing a full size pistol, especially now that we are at the beginning of November.  I will keep an eye out for that.  Generally, for a carry gun, I prefer autoadjust brightness, but there are conflicting opinions on that.

In terms of durability, I do not expect any issues.  I know that these were seriously abused during the design phase and the people at Vortex I have talked to do not seem to have any concerns about durability of the Defender red dots.  I am looking at a sample of one, so it is not like I can do anything statistically significant there.

The XL comes with either 5MOA or 8MOA dot size.  ST and CCW are available with 3MOA and 6MOA options.  I have long been a proponent of larger dot sizes in handgun red dot sights.  It seems like competition guys are on board with that (XL is aimed at them to some degree), but why you would want smaller dots on the ST and CCW that are ostensibly aimed at the consumer carry handgun market is not clear to me.  I suspect Vortex is simply giving people what they are asking for even if they are asking for something that makes no sense.

That's the difference, I suppose, between people who criticise stuff for a living (yours truly) and people who have to sell stuff for a living (Vortex).  They have to be very cognizant of what their customers are asking.  I am very curous what the relative sales numbers for different dot sizes are.

The Defender XL I have here came with an 8MOA dot and that is just about perfect.

For an example of what that looks like, here is an 8MOA dot on a 7'x12" plate at 52 yards (note that the red splash to the right of the dot is a reflection off of the camera lens; it is not there when you are using the sight).

There are several reasons I prefer larger dots: they are easy to see at lower relative brightness, they work better with mild astigmatism, they are easy to pick up.  Also, if you are shooting a little further out, it is a little easire to compensate for drop.  For example, if you sight your dot in at 25 yards, with a typical 9mm, you have about 2 inches of drop at 50 yards, about 4 inches of drop at 75 yards and about 10 inches of drop at 100 yards.  On a hundred yard plate, I just place the lower edge of an 8MOA dot on the top edge of the plate.

XL and ST use 2032 batteries.  CCW uses a smaller 1632.  All three have shake awake, so I expect the batteries to last for a while. With all three, the battery is accessible from the top, so you do not have to remove the optic to change batteries. With ST and CCW, the battery cap is simply threaded in, which is uniformly a pain in the ass for many reflex sights out there, including these.  Vortex does give you a tool for that and it sorta works, but I much prefer how they did it with the XL.  Since they had more space to work with, the battery cap is hinged at the front and is released with a simple button.  Not only does it make battery replacement a breeze, it also makes sure you can not get your fingerprint onto the inside fo the lens while messing with the battery.

Shooting with it, my initial impressions are very positive.  Everything worked as it should.  Nothing shifted.  Zeroing in was a breeze, and it stayed zeroed.

Getting on target was VERY quick.  I am not a high speed/low drag kind of guy, so I suspect in the hands of a truly skilled shooter this thing would be blazing.

The gun I have it on is a very modofied version of G17.  The frame started life as a G31 which was the first handgun I ever bought.  I have somewhere between 150k and 200k rounds fired with that frame between the original 357Sig, the later 9mm and also the Advantage Arms 22LR conversion kit.  As you can imagine, all the springs have been replaced more than once.

At some point, I sent it in for a grip reduction, since I do not like the figner grooves very much.  The grip was made slightly smaller and shortened to accept both 17 and 19 magazines.

The trigger I have in it is the Gen3 version of Haley Stregic's Skimmer trigger.

The slide is the first gen Atom from Unity Tactical with the OEM Glock barrel, Lone Wolf striker and extractor.

It is still a Glock, albeit a nice one.

For the side-by-side I am planning to do, the RMS2 sits on a Gen5 Glock 17 that is stock other than sporting a Timney trigger.  Deltapoint Micro is on a bone stock G34. 

Generally, I fully admit that Deltapoint Micro is more appropriate on a slimline G48, but I wanted the guns to be broadly comparable.  Once this test is done, the Micro will go back onto a smaller gun and G34 will be milled for a different optic, probably for Acro footprint.

NRL Hunter Planning
Rifle Configurations

As I have mentioned previously, I am looking to shoot in a couple of NRL Hunter competitions in 2025.  I have many reasons for that: preparation for the Team Challenge, leading by example (trying to get my kids interested) and simply having fun are all contributing factors.  The "trying to get my kids interested" is what usually gets me a hall pass from my wife, so that one is an integratl part of the reasoning.

One aspect of this whole decision process that needs to be addressed is the almost inevitable paralysis by analysis that every gear junkie is bound to develop when looking at the options.

Given my comparative inexperience and relatively limited shooting skills, I think my best bet is to not overthink it.  Just set up a rifle for the Open Heavy class and go practice.  I intend to shoot 6.5CM, hopefully with factory ammo.  Given that, a ltitle extra weight for controlling recoil and having good information for the second shot after I miss the first one, should be beneficial. 

On the other hand, since there are many ways to win the race for the last place, I could not help myself and tentatively configured rifles (on paper for now) for both Open Heavy and Open Light.  I plan to build them all up exactly as described below and figure out how contorted of a shooting position my aging joints can tolerate with each one.

The idea, for now, was to simply look at what I have and play with different configurations.
