Great start if you are willing to replace the hand guard. I bought this with the thought in mind to upgrade the hand guard anyways my preference for KeyMod. The hand guard is EXTREMELY heavy for 6.5" of rail and it kind of looks awkward. If they put another inch on it I probably would have left it on. Barrel is about 1-1.5 MOA at 100yds and eats steel like a champ with no polishing of the chamber. Totally pleased with the amount of quality rendered in such an AWESOME price point. If you are thinking of creating a pistol AR use it you won't be disappointed!
