Strike Industries G4MDCOMPS Mass Driver Compensator Black Aluminum with 1.41" OAL for 9mm Luger Glock 17 Gen4

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.
