FM Products offers a comprehensive Pistol Caliber Buffer Tube Kit for anyone doing a AR style Pitstol Build. Its a
complete, feature rich package with everything you need to set up the recoil buffer system that’s critical to a reliable Glock
or Colt style AR pistol build. FM includes a pistol receiver extension (“buffer tube”) made of extremely strong yet
lightweight 7075 T6 aluminum alloy. Standard with a premium Heavy Buffer, and a PCC specific Recoil Spring.
The Pistol Caliber Buffer Tube has a tough hard-coat anodized finish to resist corrosion and surface wear, with a dry film

on the outside. Inside, the kit comes standard with a Foxtrot Mike 9mm 6.5 oz Heavy Buffer, designed for proper cycling of
blowback operated 9mm AR builds. The buffer is made of 4340 carbon steel that has a harder core hardness than standard
