There are many ways to smooth the operation of a suppressed/big bore AR-15 Carbine. One of the most cost effective and quickest upgrades available, is the installation of a KVP™ H3 buffer. The KVP H3 utilizes two brass weights to achieve the 5.4 ounce buffer weight. There are many added benefits once you install a KVP™ H3 buffer. Benefits include: increased reliability, reduced wear and tear on critical internal parts, reduction in felt recoil, and reduction in bolt bounce. Manufactured to meet the highest quality, KVP™ Heavy H3 Stainless Steel Buffers are a great option for the AR-15 platform.
