The Strike Industries Mass Driver Compensator is a counter recoil system that doesn't require a threaded barrel and is designed to reduce mechanical recoil without affecting the handgun's cyclic speed.
It is compatible with GLOCK™ GEN3 and GEN5 G19 (compact) & G17 (standard) slides and can be used with most open-bottom holsters that accommodate compensators.
Installation of the Mass Driver Comp requires no permanent modifications to the firearm and is recommended to be done by a gunsmith or armorer, with a specific torque value for the guide rod nut.
