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

The Strike Industries Mass Driver Compensator is a 9mm Luger muzzle device purpose-built for the Glock 17 Gen4. Machined from lightweight aluminum with a black finish, the Mass Driver uses the hot gasses expelled through the barrel as a counter-balance system to reduce felt mechanical recoil and keep the sights flatter between shots.

This Gen 4 standard variant (part number G4MDCOMPS) features a blended, no-snag profile with an overall length of just 1.41" OAL. The Mass Driver is designed to work with most factory and aftermarket threaded Glock 17 Gen4 barrels, making it a clean, controlled-recoil upgrade for range and competition use where faster follow-up shots matter.

The kit includes the compensator main body, recoil spring, guide rod, and guide rod fitment washer for a complete install on your Gen 4 Glock 17.
