I’ve always been told never use a crush washer because the muzzle device will come loose.


A muzzle device actually stays on with a crush washer as the pressure from the tension of the washer pushing up keeps forward pressure on the shoulder of the muzzle device. The problem with crush washers is that they dont crush evenly and you introduce an angle from the shoulder to the exit of the bore of the muzzle device. On something short with a large bore like a flash hider or brake, it wont matter. On something long with a tighter bore, the angle is more pronounced as you get closer to the end of the silencer and you can induce a baffle strike.

This just happened to me with an out of square jam nut. Was barely grazing the end cap but poi was off with the can by a ton and on without. I removed the jam nut and tightened brake to manufacture specs and now it’s on with both.
