Overview
The LMT H2 Carbine Heavy Buffer is designed for carbine-length gas systems and features a heavier weight that helps to manage recoil and improve reliability in cycling. This buffer is particularly beneficial when working with .308 Winchester builds, as it helps to ensure smoother operation and reduces the potential for bolt bounce, which can lead to malfunctions. Builders often choose this buffer for builds that require enhanced performance under various shooting conditions.
