The Foxtrot Mike Products FM-9 Heavy P.C.C.Buffer Kit includes a proper P.C.C. Recoil spring, guaranteeing optimal feeding and reliability of a 9mm P.C.C.

The 6.4oz Heavy Buffer is the perfect weight to ensure reliable feeding of any blow-back operated P.C.C. 3.7 inch overall length, requires no spacer and helps prevent bolt catch breakage. Smoother function, less felt recoil, and reduced rate of fire from your AR pistol.
