    TY AU for the chance to get this Colt hardware! Some ppl r francophiles, anglophiles, im a Colt-ophile. Lower is everything i was hoping it would be. AU nailed it on the head! Every piece was Colt parts and/or the companies Colt primarily uses. The Piston Carbine 5.56mm roll mark was cool in itself! You can tell it wasnt electricall/laser etched. Always a fan of 5.56 mark instead of .223. Colt grayish finish, F2 marked A2 grip, no line on the opposing flush side of selector, long length selector lever with S safety mark on top, Schmid tool n engineering S boxed components, full mass hammer, Cerro forge lower including the key hole forge mark on right side, 4 position mil-spec receiver extension, H marked buffer, machine pressed castle nut staking not punch staking, 2 piece magazine latch, n no QR code. That was everything on my mental deduction list i wanted to see. I was very happy it hit every check mark! Thank you for selling quality Colt pieces! Very impressed AU!
