A new range of Colonel Mustard muzzle brakes and flash hiders!

This is the Triple Port design - similar to the classic Miculek-style brake (and very similar to the Colonel Mustard brakes that we have sold for years - but with a better finish and a jam nut as well as a crush washer).

  • Screws onto standard AR-15 / M4 / M16 ½" x 28 threaded barrels (with .223 / 5.56 bore)
  • This thread is also commonly used on .22 LR, .22 Mag and .17 HMR rifles - all of which are able to benefit from using this muzzle brake
  • Muzzle brake has three chambers with 8 ports (two on the top) that direct the exiting propellant gasses upwards and to both sides to reduce muzzle climb and felt recoil - allowing for faster follow-up shots
  • There are no open ports on the bottom of the muzzle brake core - this will reduce the dust signature when firing prone
  • CNC machined steel construction with smooth black Nitride coating
  • The quality of these brakes is on par with the brakes we carry from our Canadian-made suppliers
  • Crush washer AND Jam Nut included to aid fitment
  • Dimensions: 2.24" x 0.94" x 0.94"
  • Weight: 4.16 oz.

Model: CMMB05223MB

The TARHR handguard removal tool is the best we've found at installing our muzzle brakes - the non-marring finish of the plastic coating is perfect for inserting through the brake and then twisting on to crush the washer and keep it all straight and tight. Just ensure that you don't turn too far - if you back off you will need a new crush washer!
