The Aero Precision EPC Buffer Kit features our Enhanced Carbine Buffer Tube and our 7.7oz buffer and spring specifically optimized for use in the Aero Precision EPC.
Note: The 7.7oz EPC buffer, it is not intended for use in AR15 or M5 platforms. The additional length and weight will not allow for proper cycling of standard platforms.
Stock NOT Included
Note: For use in a 40S&W, 10mm, or 45ACP build we recommend the use of a heavier buffer spring.
