Strike Industries SI GEN4 G17/31 Comp Glock Mass Driver Compensator

The Strike Industries Mass Driver compensator represents a quantum leap in compensator design. Current designs have largely been unchanged since the 1930s. It’s about time for something revolutionary. The Mass Driver name is inspired by the idea of theoretical mass driver engines in space travel. By ejecting mass, an equal and opposite reaction is generated propelling the space vehicle forward.
