The Variable Velocity Device or VVD is a set that includes a piston and piston head as well as an adjustment tool. The piston has head venting that can adjust to three different positions to alter the air flow to adjust the power generated. The piston installs into a normal gearbox and then the tool can be used to adjust the valve setting from outside the gun (via the barrel).
