I have a Romanian Romak post ban 991. It was a low cap with 5 and 10 rnd mags. I have done the double stack conversion and made it 922 compliant with a tapco trigger, tactical furniture, and stainless steel piston. But I want to add a muzzle brake to it. The muzzle had a muzzle nut and is too small for the 14:1 LH threads (they barely cut into the muzzle). So my next option is to go with the 1/2-20 RH thread. Does anyone know where I can get the die and muzzle brake in that thread type. I have looked and can't seem to find any. Or should I just leave it be?
