Hey guys I have a 10 FCP-SR and just got a muzzle brake. My question is I am planning on a precision rifle build and upon reading found a few different pieces of information. One is to use a crush washer or shims. The other was to screw it on as tight as I could to have it timed correctly with blue thread lock let it dry for 24 hours then shoot. Has anyone heard of this second way of doing this? Any advice would be greatly appreciated.
