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 tungsten buffer. The KVP H3 utilizes three dense tungsten 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 Tungsten Buffers are a great option for the AR-15 platform.
