Hello, New to M4carbine.net and hope one or more of you can help me. I have a 7.62x39 AR-15 M4 with a flash suppressor threaded 1/2-28 tpi. Where I live I have to have a permanently installed muzzle brake but cant find a Medieval style .30 caliber with 1/2-28 tpi. Does someone make an adapter to go from 1/2-28 to 5/8-24? Any help would be great.
