some guy on the net from United States, WA Public Profile

This is a good alternative to red dot in general. It compares well with things like the 1x Vortex Spitfire. The one good or bad thing about this guy depending on your needs and eye sight is the reticle. I have this mounted on a 7.62 x 39 AR "pistol" and used at close ranges the big fat outer ring is vary fast and good at plinking cans out at 25 meters. Which translates well with fast and good enough close accuracy (its actually pretty great at this). However, its a chore to use trying to do deliberate slow fire on paper. The middle chevron is VARY small and hard to for me at least to print consistent groups at 50 and beyond ranges. So its a mixed bag.... When compared to my Spitfire AR I do find it to be better going fast and close. But its a struggle going longer and and precise which that Spitfire does way better. I REALLY wish Primary Arms would do up one of these with something more like their larger KISS chevron. I would pick up a couple more of them if that ever happens. The over all body and included mount are nice. It works with some after market QD mounts. Mine uses an American Defense AD-T1-L STD mount BUT note, that it mounts a lot lower and even with the after market riser from primary its a tad low (this only matters if you were trying to do weird things like mount on CX4 storm and changed your mind =). I will say that this is thing is ideal for a PCC type home defense type deal.

Over all this thing seems to be a really good optic. Glass is pretty nice. Its not Trijicon good but its better than a lot of these prism optics that are floating around. It certainly is better than my Vortex or Primary Arms stuff but not as good as my Acog. I was primarily attracted to this thing for its reticle. While I was unable to test the hold overs (yet) they seem to be good enough for your average 5.56 load. The elongated triangle, well its more like an arrow, works well enough for quick aimed shots. Its not overly large and might by a hair to small for my tastes, but this is small potato's. In fact I have only 2 gripes with this thing. The first is no QD options. But this is minor as it has the IMO, next best thing. Having a Gerber or Leatherman is QD enough for me and the mounting reminds me of a smaller 2 point M68 mount. That is just torque it down with your handy multitool and it ain't moving till you do the reverse. The bigger gripe is that you can tell the reticle is lit from the bottom left. At least on mine, half the "arrow" ends up not lit under some conditions. This CAN be made to go away by fiddling with the focus and/or playing with lighting intensity. But I do not want to have to fiddle with it at all. And this is not an issue with it not lit. However, I really do like this optic. Shockingly more than I expected. This seems to be a largely under the radar release of a quality prism optic. Well it went under my radar until last month that

I bought this off of the DVOR sight. It was paired with an AIM Surplus nickel boron 7.62 x39 bolt and ended up with a reliable, accurate, little AR pistol blaster. I had couple brands of 20 rounder magazines I gave a go (Cproducts and ACS). Both functioned well for me with one random stoppage that was magazine related with the Cproducts mag when loaded to 20 rounds. After that one hitch no issues. I had another 7.62 x39 AR rifle with me that I had built. So I naturally compared the two uppers. I can say that upper is stupid accurate with its Faxon gunner barrel and 123 grain wolf HP's. This little guy is not as accurate as that , but for me was pretty good. As I was out in the boon docks with only about a clear and safe 20 -25 yards I could shoot at I am comparing one ragged hole to on slightly larger ragged hole. My guess is that this Grid Defense is probably around a 2 MOA gun with some of the better Russian steel cased stuff. It certainly is fun. I had some concerns about this thing do to lack of reviews. And I can not say anything about long term durability but mine seems well enough put together.

The only regret I have with this purchase is did not go with the tungsten grey one, that would have looked pretty spiffy on my pistol lower. Oh well...

Used this little kit on a recent build, an Aero M4E lower and upper where used. This has slightly different lines and what not than your usual AR lower. All parts work as they are suppose too. Now I am giving in 4 stars simply in that, while I like this parts kit, I highly do not think I would buy it again if at full price. There is only ONE piece I REALLY like and do think of as an improvement, and that is hands down the magazine release. I like that it sticks out a little more and has a concave cut in it. I WOULD buy more of those. The lower pins look great, but functionally don't really do anything. SO its an, "its cool" but IMO, pointless. The selector/safety seems to be a 60/90 degree. I did not know that. So it appears I installed it as a 60 degree throw. At first I HATED it. I am so used to riding my selector back in the Army days that its just weird to have it disengage early from safe to fire. But its growing on me. Those are the BIG bits. Something funky was going on with the rear pin and spring that retain the back take down pin. Shot it across the room 5 times... Never did that before, ever. And not 5 times. No idea what was going on there. Super power spring? Aero lower hole to shallow? No idea. but had to in the end cut like 3 turns of the spring off to get in there.

All and all I personally would buy this kit again on sale. But I found out all I personally want out of it is the mag release. I think I am getting crusty and just don't see

Paired the 16 inch gunner with a Kak 7.62 x 39 bolt carrier. They played nice together and functioned perfectly with wolf and tula. I was not really shooting for groups as I was just out in the boonies but at about 35 yards just attempting to sight in the thing I was getting groups that where not making me worried. Next thing to do is actual bench this thing but the most important aspect of this project was getting a mid length, somewhat light weight upper that would actually function ok with Russian steel case and not shoot like trash. So far this has totally met my best case out come for this project. Good barrel and a happy camper. Oh, and its REALLY fun to shoot.

Previously I used this on an 18 inch .308 where it functioned but the fire ball and report were excessive. But it certainly did reduce muzzle climb. Well last month I was staring at the thing sitting on my desk and started wondering how it would do on a 7.62 X 39 AR. So I ended up building an upper last night after I got this idea stuck in my head. And it works incredibly well on this. Report and flash are what I would call normal for something like this out of a 16 inch barrel. Muzzle flip ended up being not much greater than 5.56 do to this thing. And this is with a Faxon gunner barrel which weights much less than your usual government profile. Ya, for 7.62 x 39 and probably .300 blackout a legit option for a muzzle device.

Its not quite as nice as a Harris, but it does the job I needed it to do just fine. IMO if you are mainly bench rest shooting off a bipod it probably is better to go with something better. If your like me and only using this thing in like quarries, in the boon docks, mountains, etc just goofing off its perfect. It comes out and gets swapped between a couple AR's when needed and pops off easy the rest of the time when not. Its quite good for this purpose. But I would never use this on my bench rest rifle. That got a Harris and its just more stable, but not by all THAT much.

I stuck this on an 18 inch AR10 pattern rifle. I wanted something that was not going to be as annoying to other shooters at the range like a muzzle brake (you know, THAT GUY). And in that, it somewhat does that. It sure is less bad than a full on side ported muzzle brake but also quite a bit more than a standard A2 style. It certainly does cut down on muzzle climb on my .308. But OMG, the muzzle flash! While firing all I see is a wall of flame threw my 1-8 power. Now a friend took a pic of me firing the thing on a dark rainy day and you can see that the cuts are channeling the flash, but to much is going vertical. Keep in mind once again, its on a 18 inch .308. I think the flash would be much better managed on something like a 300 blackout by this thing. So it seems to be well made and it does hit the middle ground between flash hider and muzzle brake well, for me at least I find the vastly increased muzzle flash in .308 to not be worth the reduction of muzzle climb. Going to hold on to this thing but for this rifle, I need to find another solution. If I pick up something later on that's threaded for this thing in 7.62 X39 or .300 Blackout I think a MUCH better choice. Shorter barreled .308.....ugh not so much unless you want to impress people throwing fire.

Gave it 4 stars just do to me really wanting it to work out with this rifle. It is well made and nicely finished.

I bought this for an Ar-15 but it ended up going to the range on a AR-10 pattern. Over all I think this a good optic at its price point. But it does have some fish eye at 1x. Somewhere between 1.5 and 2 it goes away. On the other extreme eye relief gets a vary picky when you get to 8x. To me it seems to work the best at 1.5x - 6x. Of course the reticle only is going to properly work at 8x as its working on the 2nd focal plane. Now for a do a lot of things optic I think it does offer quite a bit for your money.

The reticle pattern I have not decided if I like just yet. Most of these sorts of scopes have these obscenely busy do everything reticles that just get in the dang way when you sit down to just shoot groups 100+ yards. This one is no exception. However there might be something to this diamond. But I found attempting to shoot groups at 100 yards and beyond at 8x to take more effort than it needed to be since that diamond was blotting out so much of the center of the targets. What I may end up doing is sighting using the TOP of the diamond as a chevron as this would not get in the way of trying to just shoot groups. Which is why I think there might just be something to a diamond over a horseshoe. Find the happy zero for the center dot but perhaps on the 100 - 200 yard line use the upper diamond at the rounds max arc. I started out using a 50 yard zero and some 7.62 Nato ball. But when I was at the range it did not occur to be to use the upper hold over, t
