Ok I just picked up an Arsenal SGL-20. Awesome rifle but what in the world is on this muzzle? I haven't been able to find anything, and I called Arsenal and they said my rifle originally shipped with a muzzle brake. Is this just a thread protector? I'm not sure why the purchaser would have changed the muzzle device out when it doesn't seem to be a flash hider or anything of value.
Any help is appreciated.
