Description
Elevate your rifle’s performance and longevity with the Geissele Reliability Enhanced Bolt Carrier Group (BCG). Engineered for shooters who demand uncompromising reliability, this BCG is the pinnacle of bolt carrier technology.
At its core lies the Geissele Stressproof Bolt®, forged from upgraded Carpenter 158+ steel. Developed in partnership with Carpenter Steel metallurgists, this proprietary material offers a cleaner composition with fewer impurities, resulting in a bolt capable of achieving five times the service life of standard mil-spec components.
Each BCG is finished with Geissele’s exclusive NanoWeapon® coating. Originally developed alongside the Picatinny Arsenal, this advanced treatment provides industry-leading corrosion, wear, and abrasion resistance. With a surface hardness of 82HRC—harder than sand—it rejects carbon buildup, simplifies maintenance, and allows your rifle to operate reliably with minimal lubrication.
