Let me say that in no way are these "budget" uppers. I have used these on 4 different mil-spec uppers including my Colt M4,6933,6920 & BCM lowers. All fitment was perfect.Accuracy was near perfect out of the box. Very minimal adjustment & accurate out to 100 yards & kept hitting paper! Zero to 50 yards it was near dead on! Do not hesitate to purchase from this seller.As I will be purchasing additional uppers from Andro! And are you kidding the pricing for this quality is just insane! 5 Stars all the way for me!
