Sons of Liberty Gun Works A5H2 Buffer Kit – AR-15 Rifle

The Sons of Liberty Gun Works A5H2 Buffer Kit delivers smoother cycling and reduced bolt carrier velocity for AR-15 rifles. This system bridges the gap between carbine and rifle-length buffer systems, providing improved recoil impulse and more consistent bolt lockback, especially with suppressed or short-barrel configurations.

Kit includes an A5H2 buffer (4.6 oz tungsten-weighted), A5-length buffer spring (green for identification), and all necessary components for installation. Compatible with standard AR-15 lower receivers using carbine-length receiver extensions. The heavier H2 weight is ideal for mid-length gas systems and provides enhanced reliability with various ammunition types.
