TacFire BCG 9mm Gen 3 Features The TacFire 9mm Bolt Carrier Group Gen 3 is machined from steel and finished in black nitride a coating chosen for its hardness and resistance to corrosion under repeated cycling. Built specifically for 9mm Luger AR-15 platforms the BCG is designed to work with the blowback operating system typical of pistol caliber carbines rather than the gas impingement system of a standard 5.56 AR-15. Compatibility with both Glock and Colt magazine pattern lowers gives builders flexibility depending on which magazine well their 9mm AR-15 is configured around. Country of origin USA manufacturing reflects TacFire s domestic production standards for this component. As a Gen 3 design this bolt carrier group benefits from design refinements made across earlier generations of TacFire s 9mm BCG lineup. A durable steel build is intended to withstand the high round counts common in pistol caliber carbine shooting and training. Backed by a limited lifetime manufacturer warranty the BCG is built to be a dependable long term component rather than a wear item needing frequent replacement. For 9mm AR-15 builders running a Glock or Colt magazine pattern lower the TacFire Bolt Carrier Group Gen 3 is available for sale at GrabAGun.
