Not here to take sides by any means just to maybe help clarify. OP is hard headed ( I know this personally) and has been told by a very reputable smith that 1/2moa is the norm out of his SBR builds. OP is just the kind of person that is willing to spend a lot extra to get a little and if 1/2 moa is possible that's what he wants ( the best ) even though it is by far not needed for the application of the intended firearm. He just wants the most out of any firearm be it a Long Range Rifle or a 38 snub nose. I think he worded his original post a little misleading, especially on the wait part. Simply put he wanted advise on a quality barrel and maybe get lucky and find somebody that may know where one is or has had a recent experience with a quick turn around time on a barrel.
