Kynshot RB5022 Recoil Buffer Stainless Steel Shotgun

This is adrop-in replacement for the standard buffer. The hydraulic fluid and seals are made to meet mil-spec requirements and have an ambient temperature operating range of -30oF to +150oF. KynSHOT uses patented hydraulic shock absorption technology to dampen the impact of the bolt at the rear of its travel and to dampen the forward impact of the buffers weight as it chambers the next round.
