The CMMG Mk10 Complete Bolt Carrier Group Repair Kit 10mm puts the essential replacement and maintenance components for a 10mm AR-pattern rifle within easy reach. Whether you're refreshing a worn bolt carrier group or keeping spares on hand for a critical build, this kit bundles the core internals needed to keep your rifle running. It's built around CMMG's track record with 10mm platforms—a round that demands reliable, purpose-built components.
This is the kind of kit that makes sense for serious 10mm shooters who understand that preventive maintenance beats surprises at the range or in the field. You get the firing pin, extractor, ejector, and other critical wear items in one package—no hunting through a dozen part numbers or waiting on separate orders. The kit includes both the standard components and the specialty screws needed for proper assembly.
CMMG engineered the Mk10 platform specifically around 10mm ballistics and feeding characteristics, and this repair kit reflects that focus. It's a practical choice for builders, armorers, and shooters who run 10mm ARs seriously and want to maintain them right.
| Caliber | 10mm |
| Platform | AR-pattern rifle |
| Kit Contents | Bolt, firing pin, firing pin retainer pin, bolt cam pin, extractor, ejector, ejector spring, bolt spring, key (RDB), key screws (x2) |
| Manufacturer | CMMG |
The Mk10 Complete Bolt Carrier Group Repair Kit is engineered specifically for CMMG's Mk10 platform. If you're unsure whether your 10mm AR uses CMMG internals or another manufacturer's design, verify compatibility before purchase—bolt carrier group components are precision-fit to the receiver and barrel extension they were built for.
You get the bolt, firing pin, firing pin retainer pin, bolt cam pin, extractor, ejector, ejector spring, bolt spring, the key (RDB), and two key screws. It's a complete internal parts package—everything needed to rebuild or refresh a Mk10 bolt carrier group.
This is a repair and parts kit, not a complete assembled bolt carrier group. It includes all the internal components and fasteners needed to service or rebuild, but does not include the carrier itself or the assembled housing.
Use it when you need to replace worn or damaged components in your Mk10 bolt carrier group, or as a preventive maintenance refresh if you run your 10mm AR hard. It's also useful as a spare parts cache if you depend on your rifle.
