"It's keeping the muzzle very flat and tames recoil way down within .223 range. That's my rifle pictured below - a Ruger American Predator with a factory threaded 22" medium/heavy contour barrel. Chambered in .243 Win." - Evan, Edmonton, AB.

The TARHR handguard removal tool is the best we've found at installing our muzzle brakes - the non-marring finish of the plastic coating is perfect for inserting through the brake and then twisting 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! Please see last pic for correct install orientation.
Spare crush washers available (CMARMBCW308).
