Give Greg a call at Bugholes (just google it). He is a very nice guy and will help you out. You are going to have to tell him what your doing with the rifle for him to completely help and make suggestion......possible chamberings your considering, etc for him to suggest something, but he will get you there. Once you get the barrel, send it to Marty at Twisted Barrel (the link is above) and have him flute it based on what he has available (he has some good pics and descriptions on his website), chamber thread it for your brake. He does his own brakes or you can pick one out and send to him as well. 2-3 weeks later, you have your stuff back.
