The Strike Industries Mass Driver Compensator, or MDC, for the Glock 17 Gen 5 (brand part no. G5MDCOMPS) rethinks how a handgun compensator manages recoil. Instead of bolting extra reciprocating mass onto the slide the way a traditional barrel-mounted compensator does, the MDC is driven by hot gas expelled through the barrel after each shot, acting as a separate counterbalance system rather than adding weight the slide has to sling back and forth. Because the comp is separated from the pistol’s operating components after ignition, a Glock 17 Gen 5 running the MDC keeps close to stock cyclic speeds while still fighting muzzle rise, and the reduced reciprocating mass means less strain on reliable cycling than a heavier bolt-on brake. Every MDC kit includes the comp main body, recoil spring, guide rod, guide rod fitment washer, guide rod head, internal spring, and a printed warning card.
