A new fitment (1/2"x20) added to this popular 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 ½" x 20 threaded barrels (with .223 bore)
This thread is also 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
Length 2.28"
Width 1.00", tapering to 0.85" at rear
Weight 4.23 oz (120g)
Model: CMMB11522320MB
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.
