I had Caleb spin me up a 6BRA barrel. I had to immediately go underway after I got the barrel so I haven't had a chance to shoot it. The turnaround time was unreal(7 days?) and he was very easy to work with. Prices were more than reasonable and I was very happy with the entire process. I found his contact info on a 6mm forum, and they had great results with him as well. If you don't mind waiting, I should have range results in the next 6 weeks.
