muzzle break or flash hider?

[iscariot]

which of these is legal? For that matter, I have an egyptian maadi, and it doesn't have a threaded barrel. What fits this?

Go with a pin-on muzzle brake and have it permantley tac welded on by a gunsmith. If you go that route you won't get into trouble.

You should have a RML if the barrel is not threaded. Flash hiders are not permitted on post ban rifles. Only muzzlebreaks. It can be attached any way you want to the barrel except by threading the barrel.
