Overview
Built for the Aero Precision EPC platform, this buffer kit is intended to support a dedicated pistol-caliber carbine setup rather than standard AR15 or M5 builds. It combines an enhanced carbine buffer tube with a 7.7 oz buffer and spring, and it can be purchased either as a complete assembly or as the buffer alone. The kit also includes a mil-spec receiver end plate and castle nut, while the stock is not included. For 40S&W, 10mm, or 45ACP builds, Aero Precision notes that a heavier buffer spring is recommended.
