It is not a flat washer, I have what is supposed to be a crush washer, concave shaped but thick that came with my thread protector. I will admit I did not realize they were supposed to be able to crush that much though! I am assuming it just flatten the concaveness out as needed, acts like a disk spring to provide tension/friction?

However it is so hard that were I to try and tighten it to line up I am concerned I would damage the brake, or threads. Also having read on another forum about barrels with "trumpeted" and distorted rifling at the crown from threading or over tightening of muzzle devices I am erroring on the side of caution.
I will get some wood drilled to make a barrel clamp as you mentioned and see what clamping force that provides and try to tighten a bit more.
