Angstadt Arms 9mm Buffer Kit – AR-9 Platform

The Angstadt Arms 9mm Buffer Kit is engineered to optimize the direct blowback system in AR-9 pistol-caliber carbines. This buffer system reduces felt recoil and bolt bounce while maintaining reliable cycling with 9mm ammunition. The heavier buffer weight is calibrated specifically for 9mm blowback operation, smoothing the recoil impulse and improving follow-up shot speed.

Constructed from durable steel components with a black oxide finish, this kit includes the buffer assembly and spring designed for direct installation into mil-spec AR-15 lower receivers converted to 9mm. Compatible with standard carbine buffer tubes. Installation requires basic armorer tools and knowledge of AR-platform assembly.
