NEW – Quarter Circle 10 Adjustable Pistol Buffer Assembly

If you’ve ever owned a Pistol Caliber AR you know very well that fine tuning them is all about the buffer system as most Pistol Caliber ARs are blowback so there is no gas block or gas tube at all to adjust. However, fine tuning them is a must. I was absolutely surprised by the amount of felt recoil the first time I shot my 9mm PCC. Pistol Caliber Carbines are known for breaking a Bolt Catch and increasing internal wear if you don’t figure out how to slow down the Bolt. Most people end up guessing and buying a heavy buffer of any number of ounces or will buy a number of them and try them all (that’s what I did LoL). Quarter Circle 10, the industry leader and standard for Pistol Caliber ARs, has just introduced their new Adjustable Pistol Buffer Assembly which looks like a real winner.
