CMMG Buffer Assembly AR15

The CMMG Buffer Assembly AR15 is a precision-engineered recoil management component designed for AR-platform rifles. This buffer assembly absorbs and dissipates the force generated during the firing cycle, directly affecting shot control, accuracy, and the longevity of your rifle's receiver extension. CMMG manufactures components to exacting standards, and this buffer assembly represents a core upgrade path for shooters seeking to optimize their AR-15's performance.

Proper buffer weight and spring pairing are critical to the reliability and handling characteristics of any AR-15. A correctly matched buffer assembly ensures consistent cycling across different ammunition types, reduces carrier tilt, and minimizes wear on critical internal components. The CMMG Buffer Assembly AR15 (MPN 55CA9A7) is engineered to work within the AR-15 system's tight tolerances, delivering smooth operation and predictable recoil impulse. Weighing 0.34 lbs with compact dimensions (4.5 x 1 x 9.9 inches), this assembly integrates seamlessly into standard AR-15 uppers and lowers without modification.

This component serves shooters engaged in precision rifle work, duty-ready builds, and general range training who demand consistency shot to shot. Whether you're running a 5.56 NATO carbine for patrol training, an intermediate-distance competition rifle, or a suppressed setup where standard buffers may cause cycling issues, matching the correct buffer to your specific build is essential. Buffer assembly upgrades are a common maintenance item and a foundational component when tuning AR-platform rifles for reliability and accuracy.

CMMG components are widely recognized in the precision rifle community for their attention to specification and compatibility. The AR-15 buffer assembly is one of the most critical ergonomic and functional elements in the system, making supplier choice and material quality important considerations for any serious build or upgrade project.
