Mk47 Bolt Carrier Group

The Mk47 Bolt Carrier Group by CMMG is the heart of any reliable 7.62×39 rifle platform and a critical upgrade for operators who demand consistent performance in the field. Designed for both law enforcement tactical applications and civilian precision shooting, this bolt carrier group serves as the primary reciprocating assembly responsible for stripping, chambering, and extracting rounds. Whether you're building a modern sporting rifle chambered in the potent 7.62×39 cartridge or upgrading an existing platform, the Mk47 delivers the durability and reliability expected from CMMG's military-grade manufacturing standards.

Built with precision engineering, the Mk47 Bolt Carrier Group features optimized geometry specifically engineered for 7.62×39 ammunition performance, ensuring reliable feeding and extraction across varying ammunition conditions encountered in real-world operations. The carrier is manufactured to exacting tolerances, with properly hardened and dimensioned components that withstand the higher pressures of the 7.62×39 cartridge while maintaining long-term reliability under sustained fire. CMMG's reputation for producing components that cycle cleanly and operate smoothly translates directly into reduced malfunction rates and extended service intervals, critical factors for duty-grade equipment that cannot fail when it matters most.

This bolt carrier group is essential for shooters building or maintaining AR-platform rifles in 7.62×39 or those seeking a verified replacement component for existing systems. Installation requires basic armorer-level knowledge and compatible upper and lower receiver assemblies designed for the 7.62×39 platform. Operators in law enforcement, military training programs, and serious civilian shooters depend on components like the Mk47 for the consistency, accuracy, and reliability required during critical engagements or demanding training scenarios. Proper maintenance and regular inspection ensure this component performs reliably throughout its service life.
