AR-45/AR-10mm 10 oz Blowback Buffer – Pistol Caliber

PCC 10 oz Buffer: Specs

Pistol caliber carbines such as 9mm, .40 S&W, .45 ACP, and 10mm are a blast to shoot but can be tough on AR-15’s internal components.  Add a suppressor, and the increased back pressure can cause tremendous damage, without properly tuning your blowback system. The 10 oz blowback buffer helps tame the destructive forces of suppressed and standard blowback carbines and pistols.  Fine-tune your setup for the softest shooting.

FAQ

Why use a heavy buffer in a PCC?

Blowback pistol-caliber ARs have no gas system to slow the bolt, so a heavier buffer reduces bolt bounce, wear and felt recoil.
