Matador Arms Hammerhead Muzzle Brake

  • 5997

These muzzle brakes are 100% made in Canada by our friends at Matador Arms Corp in Calgary. Three angled slots and three holes on the top will blast the majority of the energy out the sides (left and right) with a little gas sent up for recoil control.

Everyone needs something on the end of their barrel, why not a Canadian brake? [clears throat] ♫ Oh Canada! our home and native (muzzle) brake / True black-gun love / Fire on RO's command. / ♫ With glowing cases we don't see you rise (muzzle) The True North Arms yourbestsourceforAR15parts... Ok I'm done

Seriously though, the Hammerhead has a few advantages over your typical vanilla muzzle brake:

  • It has tighter tolerances on the bore hole, which helps the brake to divert more gas.
  • The side ports are canted rearward, pushing the gas backwards. This counters more recoil than if they were at 90 degree angles.
  • Fit and finish is top-quality.
  • The concave exit face sends gas sideways, rather than downward.
  • The vertical ports are the largest size possible without creating a downward force.

    2. Remember to orient the crush washer with the tapered side towards the gun, as shown in the diagram below:
