“Perfect fit and finish. Black Nitride is buttery smooth, nearly imperceptible from the more expensive Nickel Boron option. Gas key staked properly. Makes for a smooth action in my latest AR build. Aero makes fantastic gear at a good price”
“The Aero nitride bcg shipped really quickly and like all Aero products I’ve bought it was flawless. I paired it with a 14.5” Ballistics Advantage barrel it’s like peas and carrots.”
