The strike industries mass driver compensator represents a quantum leap in compensator design.The mass driver compensator is driven by the hot gasses expelled through the barrel after the round is discharged, and acts as a counter balance system to attenuate mechanical recoil.Barrel mounted compensators add reciprocating mass and increase the moment of inertia to the operating system, which can have a negative effect on reliable cycling of recoil operated handguns.Finish: BlackModel: Mass DriverMaterial: Aluminum
