This FX Impact Power Plenum 750 kit for the FX Impact M3 is an upgrade which delivers more power, great for use with heavier slugs on long distances. The FX Impact 750 Power Plenum adds an extra amount of regulated air what will result in a better efficiency of the rifle with higher power levels with a lower regulator setpoint. Of course, you’re still able to reduce the power for lower velocities.
