new Colonel Mustard muzzle brake design in a short and fat (or squat!)
design, with two large vents on either side and one smaller port on the
top at the front.
The quality of these brakes is on par with the brakes we carry from our Canadian-made suppliers.
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.
