Aero Precision EPC Buffer Assembly

The Aero Precision EPC Assembled 8.1oz Buffer is optimized specifically for use in the Aero Precision EPC. Aero Precision recommends the use of a 308 carbine buffer spring in conjunction with this buffer on their EPC platform. The 8.1oz EPC buffer is not intended for use in AR15 or M5 platforms. The additional length and weight will not allow for proper cycling of standard platforms.
