In photos its looks like these are all attached with the flats on the sides of the flash hider sitting vertically. When I hand tighten mine on the left hand threads, the flats only wind up just past horizontal.

Am I supposed to put a proper fitting wrench on the flats and turn the flash hider as hard as I can the remaining 80 or so degrees, or will this strip the threads? And if not, how do I lock the flash suppressor in place and get it nice and symetrical? Epoxy on the threads?
