    Great budget build rifle, definitely better than average. I’ve put about 400 rounds through it so far. Cycles anything i put in it, including some slightly undercharged subsonic handloads as well. Doesnt say in the description, but the buffer is an H2 and weighs in at 4.5 oz. The handguard to barrel nut fitment is a little but off, but i cant expect 100% precision manufacturing from a kit at this price point. The trigger is great and breaks at about 5.5 lbs. I was going to polish the contact points to get it lower, but realized its already been done from the factory. I would buy again if i’m into getting another range toy.

    Everything is there went together very simple. Could have used a dimple on the barrel for the gas block. But that was esay enough would definitely buy again
