708747548440 The Strike Industries Mass Driver Compensator (MDC) 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. The Mass Driver Compensator is driven by the hot gasses expelled through the barrel after the round is discharged, and acts as a counter balance system to attenuate mechanical recoil. Barrel mounted compensators add reciprocating mass and increase the moment of inertia to the operating system, which can have a negative effect on reliable cycling of recoil operated handguns. By separating the compensator from the operating components after ignition, the MDC allows for close to stock cyclic speeds, and reduces reciprocating mass. The compensator of the MDC system has a widened bore to reduce baffle strikes and keyholing rounds along with a 2.5mm relief cut at the top of the rear to reduce “lipping” and damage to the face of the pistol slide. NOTE: Recommended torque value for guide rod nut is 25 lbs/in. Use with +P and +P+ 9mm ammo will produce premature internal spring wear and cause failure Package Contents: x1 Comp main body x1 Recoil spring x1 Guide rod x1 Guide rod fitment washer x1 Guide rod head x1 Internal spring x1 Warning card Product Features: No threaded barrel needed (but can be used) Eliminates the need for threaded barrels. 50 State Legal Widened bore to reduce baffle strikes and keyholing rounds 2.5mm relief cut at the top rear of comp to reduce "lipping" and damage to the face of the slide No permanent modification of weapon required Blended, no snag profile Matches with width of the slide, it can be used with open holsters, no special holster needed Counter recoil design, as the slide moves back the comp moves forward to reduce felt recoil Contours with slide dimensions to be compatible with most open-bottom holsters Precision CNC machined Threaded Barrels: Strike industries recommend use with non-threaded barrels if possible but yes, the Mass Driver Comp is compatible with most GLOCK™ aftermarket threaded barrels.

Description:

Revolutionary Compensator for Enhanced Shooting Performance

The Strike Industries Mass Driver Compensator (MDC) represents a significant advancement in compensator design, moving away from outdated concepts that have persisted since the 1930s. Inspired by theoretical mass driver engines used in space travel, this compensator effectively reduces mechanical recoil through innovative engineering.

Product Features:

  • No threaded barrel needed (though compatible with threaded barrels)
  • Eliminates the need for threaded barrels—50 State Legal
  • Widened bore to reduce baffle strikes and keyholing rounds
  • 2.5mm relief cut at the top rear of the comp to mitigate "lipping" and damage to the slide face
  • No permanent modification of the weapon required
  • Blended, snag-free profile
  • Matches the width of the slide, allowing use with standard open holsters
  • Counter recoil design: as the slide moves back, the comp moves forward to lessen felt recoil
  • Contours with slide dimensions for compatibility with most open-bottom holsters

Compatibility:

Designed for GLOCK™ GEN3 OR GEN5 G19 (compact) & G17 (standard) slides. The SI Mass Driver Comp sits flush with OEM GLOCK™ slides, making it suitable for most open-ended holsters that accommodate compensators.

Installation Notes:

  • Recommended torque value for guide rod nut is 25 lbs/in.
  • Use with +P and +P+ 9mm ammo may lead to premature internal spring wear and potential failure.
  • Loctite® Threadlocker Blue 242® should be applied on all threads.
  • Gunsmith or armorer installation is advised.
  • Tested with factory GLOCK™ components; performance may vary with third-party compatible components.
