Ensures Reliable Cycling of Your "AR-9" Carbine

The Angstadt Arms 9mm AR-15 Buffer Kit provides the correct weight and size buffer for reliable cycling of your 9mm blowback AR-15. Just in case you ask: the standard rifle or carbine buffer isn’t the correct weight for an AR-15 chambered for 9mm Luger.

  • 5.4oz carbine buffer
  • Carbine buffer spring
  • Aluminum buffer spacer

A wear-resistant matte black finish on the all-steel Angstadt Arms 9mm AR-15 Buffer Kit protects it from corrosion and surface wear for a long service life.
