Found a really good deal on a 4 pin muzzle brake adapter & threaded brake at the fun show today so I figured I'd give it another try.
Marked the pin holes once I had it on & aligned correctly, then slightly drilled out an indentation for the set screw to fit in when tightened. Cleaned everything off with brake parts cleaner & let dry. Applied blue loctite, reinstalled & tightened it down very snug.
I think I'm done unless I get the urge to paint it camo.
