Specialized M5 buffer designed for .308 carbines with collapsible stocks. USA-made component for builds and replacements. Not compatible with full-length rifles or AR15 platforms.
The Aero Precision M5 .308 Carbine Buffer is engineered specifically for shorter .308 carbine platforms featuring collapsible buttstock configurations. This is not a universal buffer—it is purpose-designed for the unique cycling requirements of .308 carbine-length systems.
Whether you're building a new .308 carbine or replacing a worn buffer in an existing rifle, this component ensures reliable function and proper cycling. The shorter length is critical to carbine operation and cannot be substituted with standard rifle-length buffers.
Aero Precision components are known for precision manufacturing and durability. This buffer will provide consistent performance across thousands of rounds when properly matched to your carbine platform.
