Where did you get that flash hider? I tried to get one and was told it couldn't be exported.
That sounds like the trick. I'll give it a shot -- the rifle was put together by a guy with a good reputation so I suspect the FH is torqued correctly so it's unlikely to loosen.make a index mark with a magic marker, shot few hundred round downrange, it the FH is unscrewing itself, than flip it, if not take some solvent and wipeoff the index mark, so you don't look like a noob.
