The Q LLC ACCHBBCG2PC boasts superior quality among Bolt Carriers\' Groups (BCG) as it not only bypasses but also surpasses standard Mil-Spec guidelines. Q\'s distinction is in its precise front-end design and size, ensuring top-notch control over crucially important features. This illustrates scholarly engineering at its finest. The Two Piece BCG is a novel unit purposefully constructed using modern machinery and advanced materials. Its framework is divided into two parts: The Front-End and The Rear-End. The front end comprises Maraging Stainless Steel, coupled with a Nitride Coating for an elegant black finish. In addition, it features a SCAR-cut, a remarkable addition to fend off bolt bounce occurrences. It comes standard with a Mil-Spec Gas Key and Staking, Mil-Spec Bolt, Mil-Spec Cam Pin, and Mil-Spec Firing Pin. On the other hand, the Rear-End is made of bare Stainless Steel, which has undergone heat treatment for ultimate durability. Rest assured, it aligns perfectly with Mil-Spec length requirements. Designed to house the firing pin, it abolishes the need for intrusive firing pin retaining pins, thus leaving no room for broken pins. This feature makes the users\' lives easier. Lastly, a solitary pin secures the Carrier, paving the way for effortless field stripping.
