I'm still waiting for a BB 6mm TCU but it's "only" been a few months. I think the problem is that many of the barrel makers don't have barrels with lugs all ready to go. If they did, all they'd have to do is cut to length, crown, chamber, and finish, and the turn around would be fairly quick. Instead I think they basically start from scratch when the order comes in. I think the exception to this is SSK. Their turn around is much shorter from what I hear. It seems to me that JD is just much better at running his business. His prices are up there, but from what I hear his quality is top notch.
