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 KVP 10oz tungsten blowback buffer helps tame the destructive forces in suppressed and standard blowback AR15’s. Do yourself a favor and fine tune your setup for the softest shooting PCC possible! Due to tungsten weight variation, actual weight of the buffer is between 10 and 10.1 ounces. 10oz Buffer Features: Use in 9MM, 10MM, .40 S&W, or .45 ACP blowback AR systems. Increases AR-15’s dwell time in blowback setups Quiets action (better for suppression) 10-10.1oz actual weight (tungsten weights can vary slightly) 4 1/8″ OAL (Buffer spacer is NOT required) Stainless Steel Body Increases Reciprocating mass and weapon reliability Reduces wear on critical internal parts Reduces felt recoil Designed only for Carbine Length Stock and pistol kits.
