Used this kit on my first build. Very easy to assemble and performed flawlessly!

great kit. had the company assemble the upper and the gun runs great. only complaint i had was the saftey selector in the lower parts kit was pretty crappy so i switched to a different one but other than that, from what ive seen these are great and affordable guns. ive only run about 30 rounds through mine so far but its awesome. keep in mind these pistol kits with the short barrels like this are VERY loud. quite noticably louder than a standard 16in barrel. also keep in mind, if you have them assemble the upper they may lock-tite the muzzle attachment to the barrel, they did mine and it was a pain to get it off the barrel but overall i am pleased with these guys and have already put in another order!

Awesome kit overall. The only issue so far is that the barrel in the description list both 5.56 and .223, but I have only been able to close the bolt on .223 ammo. I don't have gauges, but it seems the barrel is definitely only for .223.

Just ordered today great price

Bought this kit for my first build, So ecstatic ,assembled less than hour, order with the complete upper assembled, shot it next morning, Scooter at the range was impressed with the sound of the fake can muzzle. Many requests to shoot it even the Owner of range ask to shoot it. very satisfy
