Ensure your AR-15 cycles reliably with the Noveske H2 Carbine Buffer weight. This buffer weight is designed to work with a carbine or mid-length gas system and a carbine buffer tube. The Heavy buffer weighs 4.8 ounces, much more than most standard carbine buffer weights and can help to reduce felt recoil without sacrificing reliability. The Noveske H2 buffer contains two steel and one tungsten weight to reach the overall weight. If you want to build or upgrade your AR-15 to have minimal recoil while still maintaining reliability, the Noveske carbine H2 buffer might be the one for you.
