Strike Industries Mass Driver - Best Recoil Reduction

strike industries mass driver glock 19 comp

This new counter mass Glock compensator (MDC) works for Glock 19 Gen 3, 4 and 5. This unique system creates an equal and opposite reaction when the bullet exits the barrel. It replaces the stock recoil spring for this upgrade.

Expel Hot Gas - Hot gas moves the compensator as a counterbalance to reduce muzzle climb

Easy Install - Legal in all 50 states, swap out the stock guide rod, tighten the comp - You're good to go!

Faster Dot Acquisition - Less muzzle climb means reacquiring the red dot faster > faster follow up shots

Conversion Barrel Compatible - Works with Glock 19 compatible conversion barrels (Always check)

No Barrel Attachment - The comp mounts independently of the barrel to eliminate any negative effect of reliable slide cycling (No cycling impact)

Works With Non-Threaded Barrel - No need to purchase aftermarket threaded barrel - Huge savings


  • Great at reducing muzzle flip
  • No timing alignment required
  • No threaded barrel required
  • Threaded barrel fits as well
  • Faster follow up shots


  • Increased recoil spring tension making it a bit stiffer to charge the slide
  • A bit difficult to install the new recoil spring guide rod
