Overview
Built for Aero Precision EPC setups, this buffer kit is intended to support a 9mm Luger AR-style build with components matched to that platform. It includes the Enhanced Carbine Buffer Tube, an 8.1 oz EPC buffer and spring, plus a mil-spec receiver end plate and castle nut, while the stock is not included. Aero Precision notes that the 8.1 oz buffer is not intended for AR15 or M5 platforms, as its added length and weight will not allow proper cycling in standard configurations. For builders working in 40 S&W, 10mm, or .45 ACP, a heavier buffer spring is recommended.

- Designed specifically for the Aero Precision EPC, so it is not intended for standard AR15 or M5 platforms.
- Stock is not included, so this is a buffer kit rather than a complete rear-end setup.
- For 40S&W, 10mm, or 45ACP builds, a heavier buffer spring is recommended, which may require additional setup consideration.
- The kit can be purchased as an assembly or as the buffer alone, so buyers should confirm they are selecting the configuration they actually need.
