Gunner 3 Port Muzzle Brake w/ MuzzLok®

The Gunner 3 Port Muzzle Brake is the ideal blend of usability, versatility, and recoil reduction. The 3 ports work to sequentially capture the propellant gasses and redirect them to the sides for maximum recoil reduction. On barrels of all lengths, the GUNNER reduces recoil by more than 50%!

The GUNNER is 100% 3-Gun Nation, USPSA, and IDPA legal for all divisions.

  • Material: Steel
  • Finish:  Salt Bath Nitride
  • Thread:  1/2"-28 TPI
  • Weight:  2.9 ounces w/ MuzzLok Nut

Faxon's invented "Muzzlok" feature on this device allows for easy timing and installation of your device without the need for a crush washer or shims. By using the extension nut to adjust the length of the device, you can adjust the rotational timing. It is recommended that you tighten the device to the recommended torque specification of 20-25 foot pounds. By not having to overcome the resistance of the crush washer, this allows devices to be removed and reinstalled in the field if desired.

  • No crush washer needed. 
  • Attach and remove in the field. 
  • Time your muzzle device quickly and easily.

    Gunner 3 Port Muzzle Brake w/Muzzle Lok for .223/5.56

    Posted by Gary on Nov 15th 2018

    FANTASTIC, easy to install, looks great, and reduced muzzle flip by at least 50%. Put it on an 18" Faxon Gunner barrel, used with a Fostech Echo II trigger. Made the rifle controllable at last. Great combination on a Safeside Tactical rifle built in Roanoke Virginia. Shooting Aguila .223, with another rifle shot 3 to 4 inch groups with this ammo at 100 yards. Now on this rifle with the Faxon barrel and break and a red dot with 3x multiplier I am getting 3/4 inch groups at 100 yards.

    The brake came within a couple of days of ordering. Installation was a breeze. Took it to the range yesterday and was pleased with the performance. Reduced felt recoil by better than 50%. Blasted shooters in the next bay so be careful who is next to you.
