The CMMG 55CA9A7 Buffer Assembly is a stainless steel A1-style rifle buffer built for AR-15 platform rifles running a rifle-length (A1) receiver extension. Machined to meet or exceed mil-spec tolerances, this buffer drops into any mil-spec AR-15 action spring and A1 buffer tube, giving builders and armorers a reliable replacement for a worn component or a solid foundation for a classic rifle-length build.

Constructed entirely from stainless steel for corrosion resistance and long service life, the 55CA9A7 weighs in at approximately 5.2 oz and provides consistent cycling and dependable function for rifle-length AR configurations. As a drop-in mil-spec part backed by CMMG's reputation for quality AR-15 components, the 55CA9A7 is a straightforward upgrade or service part for any rifle-buffer AR build.
