The Impulse foregrip is an over-sized expanded volume chamber for the pressure balanced poppet valve. It provides a buffering reservoir of gas immediately adjacent to the valve, to prevent velocity drop-off under rapid fire. The bottom of the foregrip also contains an integrated relief valve to protect the Impulse from over-pressurization in case of a compressed air system regulator failure.
