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.
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.
