Angstadt Arms AA09BUFKIT 9mm Buffer Kit for AR-15 Pistol Caliber

The Angstadt Arms AA09BUFKIT Buffer Kit transforms standard AR-15 platforms for reliable 9mm operation, eliminating the feeding and cycling issues common with improvised conversions. This purpose-built system delivers consistent performance across various 9mm loadings while maintaining the familiar AR ergonomics shooters demand.

What Makes This Different

Unlike generic buffer systems, this kit features caliber-specific weight distribution optimized for 9mm ballistics. The buffer assembly reduces bolt velocity to prevent premature wear while ensuring positive extraction and ejection. Standard carbine buffers create timing issues with pistol caliber cartridges, but this system maintains proper dwell time for reliable cycling with both subsonic and supersonic ammunition.

Key Features

• Precision-machined buffer assembly with 9mm-specific weight configuration
• Heat-treated steel construction for extended service life
• Compatible with standard AR-15 lower receivers and carbine extension tubes
• Optimized for blowback operation with dedicated 9mm upper receivers
• Reduces bolt bounce and improves extraction reliability
• Works with both Glock and Colt-pattern 9mm magazines
• Drop-in installation requires no permanent modifications

Field testing demonstrates consistent cycling across temperature extremes and ammunition types. Competition shooters report improved split times due to reduced muzzle rise and faster target reacquisition. Law enforcement agencies appreciate the system's reliability during high-volume training sessions. The buffer's weight distribution minimizes wear on bolt extension and barrel extension interfaces.
