I walked into this skeptical I am here writing my review after using it for quite a while now. I had got this in March of 2020. It has been absolutely 100% reliable I only cleaned it today Aug 3 2021 after maybe close to 2,000 rounds. (give or take) I did notice some pieces of primer or brass in the Firing pin channel so this is something to be aware of after around 2k rounds. Other than that, the build quality is insane compared to much of any DI on the market. You'll get typical ware of the carrier finish and the gas key is properly staked on mine. I do have to make the prospective buyer they do use YFS screws. Overall for the 5.56 upper I bought, the accuracy was exceptional out well beyond the effectiveness of it's Barrel. I do recommend building one if you can't get a sig rattler. This in my opinion was the last bit of the wheel you could have reinvent before going to a piston gun. This gun convinces me AR 15s in the future will shorten their length like this is a real thing and it's not a compromise.

The quality cannot be overstated. There's nothing I don't like about this product except the fact that its expensive, but you really do get what you pay for. I bought this kit to mate it with a Sharps Brothers lower and a rise armament trigger and Sig Romeo 5 red dot. The buffer system/bolt assembly allows this AR pistol to be a total of 18.75 inches with stock collapsed. The parts are obviously a cut above what you see on the market today. The coatings on the parts not only look good but are flawless as well. I used 55 grain PMC ammo and got very good results at 50 yards with groups under 3.5 inches shooting from a bag. The brake does direct much of the sound away from the shooter so this a big plus.

This little setup is absolutely awesome! Excellent quality and super easy to put together! I picked up the 5.56 version and now going to grab the 7.62 also. As my title for this review says… I believe everyone should own at least one!

Instant fun gun. Solid piece of equipment comes with everything shown. If your not sure and your reading this BUY it!!!!!! It fits in a Regular Sport back pack very solid and great finish. I run Romeo 4s red dot on top of these platforms perfect height instantly in the right spot every time I bring the weapon up.

Great quality product. Very robust. Love that it comes with a grip and legit Radian LT charging handle. I used a radian lower also in FDE and it looks perfect. Only minor complaint is the stock slide when fully collapsed interferes with the bolt catch, but not a deal breaker by any stretch.
