You need a shim kit to index some brakes crush washers don't always work

I've only ever seen one muzzle device that couldn't be timed with a crush washer that was an XM177 modulator, if you are mounting a can on the gun you have to use shims since you could in theory get a washer that doesn't crush evenly and cause a baffle or end cap strike but that's a nonissue in Canada since suppressors are unobtanium for normal people here.
