Based on real Army research into the amazingly effective howitzer-style muzzle brake, the Crosstac® Mk 109 redirects propellent gasses forward into a material wall in front of the muzzle. This wall creates a surface that the gas pushes forward, countering the rearward impulse. That means outstanding recoil reduction for you—with the added benefit of virtually no muzzle climb.

The Mk 109 is fully caliber-specific…meaning the ports are sized to the caliber, and timed in distance from the muzzle crown based on caliber-specific calculations per the US Army's research. Bottom line—the Mk 109 is a serious piece of hardware for shooters who demand the ultimate in recoil-killing performance.

  • Class 3 threads are very tight for minimal slop
  • Approx. 1" diam. x 3" long, 2.8 oz.
