CMMG Bolt Rehab Kit – AR-15

The CMMG Bolt Rehab Kit contains all the small parts needed to rebuild or service an AR-15 bolt carrier group. This kit is designed for shooters who want to restore a worn bolt, replace lost or damaged components during routine maintenance, or keep critical spare parts on hand. It's a cost-effective alternative to replacing an entire bolt when only the cam pin, gas rings, or extractor components need attention.

Includes the cam pin, firing pin retaining pin, extractor pin, extractor spring, and gas rings—all manufactured to CMMG's mil-spec standards. These are drop-in replacement parts that require no special tools beyond a standard AR-15 armorer's kit. Basic familiarity with AR-15 disassembly and bolt maintenance is recommended.
