Add a little functional flare to your next PCC build with the Guntec USA Black Nitride .45 ACP Bolt Carrier Group. This solid hunk of steel is machined from 8620 steel and features a rear weight to help improve reliability and reduce recoil with the blowback system. The Salt Bath Nitride coating applied to the bolt physically changes the surface of the steel to be extremely hard and frictionless for smooth function and easy of cleaning. It also results in a deep black color that will match the rest of your build. The fake gas key is held in with grade 8 screws that are staked to prevent them from coming loose. The Guntec .45 AR Nitride Bolt Carrier Group is perfect for your next PCC build.
