Angstadt Arms AA09BUFKIT 5.4oz Buffer Kit 9mm Luger AR-15

The Angstadt Arms AA09BUFKIT is a complete 9mm AR-15 buffer kit that delivers every component needed to keep a pistol-caliber carbine cycling reliably. Built around a 5.4oz stainless steel carbine buffer measuring 3.25", this kit is engineered specifically for 9mm Luger AR-platform builds and is fully compatible with both Glock and Colt pattern 9mm magazine systems.

The included .75" spacer brings the installed length to 4", while the orange bumper provides consistent cycling contact inside the buffer tube. Whether you are assembling a fresh 9mm pistol-caliber AR or refreshing the wear components on an existing build, the AA09BUFKIT covers the key internals in one straightforward package.

Kit Includes:

• 9mm AR-15 carbine buffer assembly (5.4oz stainless steel)
• Carbine buffer spring
• 9mm buffer spacer

Designed to drop into most standard AR-9 buffer tubes, the AA09BUFKIT is a clean, no-guesswork upgrade or replacement for any 9mm pistol-caliber AR-15 build.
