The CMMG AR-15 Bolt Rehab Kit (brand part no. 55AFF68) gives a shooter a genuine CMMG way to refresh a worn bolt without replacing an entire bolt carrier group. Rather than tossing a bolt that’s still fundamentally sound but showing wear on its smaller wear parts, this Mil-Spec kit supplies the extractor, firing pin, cam pin, and gas rings needed to bring it back into reliable service. It’s a cost-effective option for a shooter maintaining a well-used AR-15 who wants to extend the life of an existing bolt rather than buying a new one outright.
