AR PCC/9mm Extended Buffer

The AR 9mm Extended Buffer is purpose-built for 9mm AR PCC platforms running a straight blowback operating system and A5-length or extended receiver extensions. Its increased length prevents bolt overtravel, reducing stress on the lower receiver and improving reliability in pistol-caliber builds. This extended 9mm buffer is heavier than standard carbine buffers, providing better recoil management and slowing down the cycle rate – especially important for suppressed 9mm builds or full-auto configurations.
