I can't say for sure but I'd try either Action Arms, 5333 S. Mingo, or Crusader Tactical, 101st and S Elm Pl in Broken Arrow.

Just put at birdcage flash suppressor back on it for a protector. Used crush washer and loosely tighten it. I'm using them on a couple of rifles that were threaded for suppressor.
