    As always AU had the best price, why buy a different brand when you know these are Colt and they will be good quality and function properly.

    Great rings

    They are gas rings, they function well and fit well. It’s kind of like reviewing screws in a deck-they are there and do their job and unless they are crap they aren’t noticed. These aren’t crap. You will happily forget about them and enjoy your rifle.
