Product Info for Kaw Valley Precision Stainless Steel Heavy Tungsten Buffer

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 ytheir blowback system. The KVP 10 oz tungsten blowback buffer helps tame the destructive forces in suppressed and standard blowback AR15's. Do yourself a favor and fine tune ytheir setup for the softest shooting PCC possible!image
