Colonel Mustard muzzle brake. The quality of these brakes is on par with the brakes we carry from our Canadian-made suppliers. Screws onto standard AR-15/M4/M16 ½" x 28 threaded barrels (with .223 / 5.56 bore). Includes crush washer and jam nut. CMMB05223MB.
Part Number: CMMB05223MB
Availability: In Stock.

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

We recommend a screwdriver with a few wraps of duct tape around the shaft - insert through the 'gills' of the brake and then twist 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! See pic for correct install orientation.
