Product Description The Strike Industries Mass Driver Compensator (MDC) is a revolutionary pistol compensator designed to reduce muzzle rise without requiring a threaded barrel. Built to install without permanent modification, the Mass Driver uses an innovative, widened-bore design to help reduce the risk of baffle strikes and keyholing while delivering improved control during rapid fire. A relief cut at the top rear of the compensator helps minimize "lipping" and potential slide-face damage, making it a practical upgrade for Glock 19 Gen 4 platforms. Product Highlights No-thread compensator design helps eliminate the need for a threaded barrel (threaded barrels can still be used). 50-state-legal configuration and installs with no permanent firearm modifications required. Widened bore helps reduce baffle strikes and keyholing for more consistent performance. 2.5 mm top rear relief cut helps reduce "lipping" and potential damage to the slide face. Kit-style assembly includes the compensator body and recoil system components for fitment.
