I need a radial type muzzlebrake. The only problem is my barrel is 1.350 dia. I also need the thread to be 5/8-24 so my suppresor can be used but, I will be able to put a brake on the rifle when im in non-suppresor freindly states. Ive been looking but cant find a 5/8-24 brake that is that big. Its a 30cal barrel so 5/8 will do fine. Does anyone know someone who can make one????
