I am not going to debate here whether or not a person should use or not use a muzzle brake. It has been debated here many times with no clear winner and i don't think there will ever be one. With that out of the way my advice is to contact Devin at Sinarms. Try by phone as that seems to be the best way to get him. He has threaded 2 out of 3 of my threaded barrels (1 was used and came to me threaded) and they were done very well and great machine work. Devin and I talked about threading a 30-06 sporter savage barrel I had and came to the conclusion that it was possible if we cut it back just a bit. I ended up getting a Savage 116 30-06 new take off in Magnum contour and had that threaded, so I cannot say that I have done it to a sporter but it should work fine.
