Correct-Spec Components To Ensure Reliable Function of Pistol ARs
The FM Products 9mm AR-15 pistol receiver extension assembly is a complete, one-stop package with everything you need to set up the recoil buffer system that's critical to the reliable functioning of your pistol. FM includes in the kit a stubby pistol receiver extension (yes, also called the "buffer tube") made of extremely strong yet lightweight 7075 T6 aluminum alloy.
The tube has a tough hardcoat anodized finish to resist corrosion and surface wear, with a dry film lube interior coating that promotes smooth movement of the buffer inside and (if you install one) a pistol stabilizing brace on the outside.
Inside, a Foxtrot Mike 9mm Heavy Buffer has the correct weight for proper cycling of blowback operated 9mm AR-15s (we like to call ’em "AR-9s") with minimal bolt bounce. The buffer is made of pre-hardened 8620H carbon steel that’s "H" rated to ensure harder core hardness than standard 8620 steel, which is pretty hard on its own! A heavy-duty stainless steel music wire spring is included, and it’s specifically designed to work with the buffer to ensure reliable operation of your 9mm pistol AR-15.
