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 10 oz 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 10.3 and 10.5 ounces.
Mil-spec AR-15 triggers typically have an 8 to 9 pound trigger pull with factory springs. Utilizing the KVP Reduced Power Spring Kit should achieve a trigger pull reduction of 2 to 4 pounds. A 5 to 6 pound trigger pull is typical after installation of the KVP Reduced Power Spring Kit.
The KVP reduced power springs are designed to reduce trigger pull weight in Single Stage triggers. Due to the magnitude of triggers on the market, KVP can not guarantee that ALL triggers will adequately detonate ALL cartridges. We recommend high quality brass cased ammunition loaded with commercial primers for the best results. Installation should be performed or overseen by a competent gunsmith.
