Aero Precision AR15 Carbine H Buffer Kit

Aero Precision AR15 Carbine H Buffer Kit

The Aero Precision AR15 Carbine H Buffer Kit provides a complete carbine-length buffer system built around an H heavy buffer for AR-15 rifles, carbines, and pistols. With more mass than a standard carbine buffer, the approximately 3.8 oz H buffer offers a practical tuning option for builds that cycle harder than necessary while remaining lighter than H2 and H3 configurations.

Aero Precision pairs the H buffer with a 6-position mil-spec receiver extension machined from 7075-T6 aluminum, a carbine buffer spring, receiver end plate, and castle nut. The result is a ready-to-install AR15 carbine buffer kit suitable for a new lower receiver build or replacing worn buffer-system components.

H Buffer for AR-15 Carbine Systems

The included H buffer weighs approximately 3.8 oz, adding modest reciprocating mass compared with a standard carbine buffer. Increasing buffer weight can help slow bolt carrier movement in properly configured rifles, making an H buffer useful for some over-gassed AR-15s, short gas systems, and other builds where a standard carbine buffer allows excessive carrier velocity.

The complete Aero Precision H Buffer Kit weighs approximately 10.8 oz. Buffer selection should be matched to the rifle’s gas system, ammunition, barrel configuration, and operating characteristics to maintain dependable cycling.

7075-T6 Mil-Spec Buffer Tube

The included carbine receiver extension is precision machined from 7075-T6 aluminum and features a 6-position design for adjustable stocks that fit mil-spec diameter buffer tubes. The stronger 7075 alloy makes this a durable foundation for an AR-15 carbine stock and buffer assembly.
