Crushwasher(Not the best from an engineering standpoint, but has proven reliability). Precision Shims(least chance but adds extra mating surfaces). The Engineering hierarchy of “timing” a brake from best to least is: Direct brake to barrel contact at the shoulder via gunsmithing or CWES style bushing system(no chance of coaxial misalignment). The geometry of the threads not only pull against one another, but the also exert compressive force towards the bore.ĥ. The threading of a muzzle requires a certain amount of tension for the muzzle to maintain structural integrity. We have yet to see any evidence of accuracy degradation in 100’s of groups and rifles tested.Ĥ. A properly installed crush washer should NOT harm accuracy. The low weight and shorter length of a brake precludes this.)ģ. (the added length and mass of a suppressor can compress one side of the spring under recoil/barrel flexing, causing a coaxial misalignment and in turn, baffle strikes. A crush washer is technically NOT a washer, it is a cone shaped spring. NEVER use a crush washer with a suppressor!!!(see #2)Ģ. Let’s get a couple of things out of the way ġ.
