Q AR-15 .223 / 5.56 Two Piece Bolt Carrier Group

The Q® AR-15 .223 / 5.56 Two Piece Bolt Carrier Group features 2 sections, The Front-End and The Ass-End. The ASS-End is constructed with heat-treated stainless steel and is built to Mil-Spec. This end holds the firing pin and eliminates the need for firing pin retaining pins. The Carrier is retained with a single pin for easy field stripping. The front end features Maraging stainless steel construction with a corrosion-resistant Nitride coating and it's SCAR-Cut to help prevent bolt bounce. It comes standard with a Mil-Spec gas key and staking, Mil-Spec bolt, Mil-Spec cam pin, and a Mil-Spec firing pin.
