A new range of Colonel Mustard muzzle brakes!
The quality of these brakes is on par with the brakes we carry from our Canadian-made suppliers.
This is the Gen 2 Triple Port Design - a subtle update/refresh of the classic Miculek-style brake.
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 9 ports 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
Crush washer AND Jam Nut included to aid fitment
Dimensions: 2.28" x 1.00" x 1.00"
Weight: 3.88 oz.
Model: CMMB115223MB
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.
