Lead and Steel H2 Buffer/Spring Combo Features The Lead and Steel H2 Buffer/Spring Combo is built from steel giving it the added weight needed to slow bolt carrier group velocity compared to a standard carbine buffer. That added mass helps absorb some of the energy generated during cycling which can translate into a noticeably softer felt recoil impulse for the shooter. This is particularly useful on rifles running a carbine length gas system with a shorter barrel where the gas system can otherwise cycle the action too quickly. A properly weighted buffer also helps reduce the chance of bolt bounce which can cause reliability issues over time. The included spring is matched to the H2 buffer weight ensuring the two components work together rather than fighting each other during the cycle. At 4.60 ounces the H2 weight sits between the standard carbine buffer and heavier H3 options making it a popular middle-ground choice for many shooters. This combo is especially useful for suppressed rifles where the added back pressure from a suppressor often calls for a heavier buffer to maintain reliable function. The Lead and Steel H2 Buffer/Spring Combo is available for sale at GrabAGun for shooters looking to dial in smoother more reliable cycling.
