CMMG Bolt Rehab Kit AR-15 223 Rem/5.56 NATO Bolt Parts Kit

The CMMG Bolt Rehab Kit is a replacement parts kit for the bolt assembly of an AR-15 rifle, chambered for 223 Remington, 300 Blackout and 5.56x45mm NATO. It is intended for rebuilding or refreshing the bolt carrier group rather than as a complete carrier.

The kit covers the components that wear or fail in service, including the firing pin, firing pin retaining pin, cam pin, extractor and extractor spring assembly, ejector and ejector spring, and three gas rings. The parts are finished in black to match the rest of an AR-15 bolt carrier group.

The package includes a firing pin and retaining pin, cam pin, extractor, extractor pin, extractor spring, extractor O-ring, ejector, ejector roll pin, ejector spring, and three gas rings. The retailer states these are the same parts CMMG uses in its own rifles and kits.
