8 Ounces Buffer Kit For 9mm, 40S&W, and 45ACP Carbines To Reduce Recoil

This Angstadt Arms Buffer Kit is a complete drop-in replacement that works flawlessly with blowback AR-9 style firearms chambered in 9mm, 40S&W, and 45ACP.  The buffer weighs 8 ounces and is constructed from steel with a Manganese Phosphate finish.

The buffer is made with extra weight to help reduce recoil by slowing down the bolt during the cycling process.
