I was amazed, I purchased two of these kits, The build went flawlessly, so many parts, so many places to put them. NO ERRORS, No shortages, many thanks to whome ever put this 20″ barrel ar 10 package together. Have not been able to live fire yet, but all dry firing (including primer only firing) looks like a sweet shooter. I will return to add review after a trip to the range. *(note it will be a while as the ranges here are closed for winter)

As promised here is the follow up, I took y ar10 to the range today, I am still amazed. The rifle worked without a flaw. It took only seven rounds to zero in the scope, followed woth a six round group check. at 50yards a 1.25″ group I couldn’t be happier. the action was very smooth, even the no frills trigger worked very comfortably. I reccomend this kit very highly.

Recieved my 20″ .308 rifle kit. In about a week and a half. All parts were present. Quality is great. This rifle turned out great and is a straight shooter. Cycles rounds smoothly and I have not had a problem…..

When I purchased this rifle I wasn’t expecting a whole lot, considering how cheap it was. Boy was I surprised. After completing my build took it out back and ran a couple of boxes of ammo thru the gun, I used three different brands. Was very smooth action, nice crisp trigger. The rifle is just a bit on the heavy side at 12 pounds, but that actually helped with the recoil. There was virtually no recoil which was really nice considering the calibre. I had a 1 1/4 inch group at 200 yards. No problems with any aspect of this rifle. Will be recommending this kit to anyone that asks.

Several rifle kits bought and a few 80% lowers , none of which have let me down . Thank you guys for offering such great products at affordable prices. I’ve have literally shot a couple thousand founds out of a few of the builds with no issues to date.

Amazing rifle kit it went together super easily. The quality of the barrel is top notch I shoot it out to 400 yards and it maintains consistent 5-6 inch groups. The trigger is high quality but I swapped the trigger kit for a new CMMG kit. Nothing wrong with the trigger at all i just like the feel of my CMMG. Overall this is an extremely great value with the quality of much higher priced kits. 10/10 recommend if you want a fantastic AR-10 for great price.
