Add a little functional flare to your next 9mm AR build with the Guntec USA PVD 9mm 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 Rainbow Physical Vapor Deposition coating applied to the bolt physically changes the surface of the steel to be extremely hard and frictionless for smooth function and ease of cleaning. It also results in a bright rainbow effect that changes color in the light. The fake gas key is held in with grade 8 screws that are staked to prevent them from coming loose. The Guntec 9mm AR Bolt Carrier Group is perfect for your next PCC build.

  • Rainbow Physical Vapor Deposition bolt – 8620 steel
  • Magnetic particle inspected
  • Hydraulically staked gas key
  • Compatible with Glock and Colt lowers
  • Grade 8 gas key screws
