Well,I'm still waiting on my coleiran .50 B profile 44" swamped bbl for my Jacob Dickert "kit" from tow. Its been several months and as you all know you cant do much to a build without the tube. They do send me e-mails often telling me as soon as they get it they will send it. The only thing I have been able to find is a rice bbl in .50 w/ the same contour, but it is 42" instead of the 44" I had my heart set on.If something doesnt come up soon I guess I will go with the 42", but I'm worried that it may not fit in the bbl channel as I beleive it was inletted for the 44".Any thoughts on whether it will fit or not? I suppose I should contact totw and ask them.Thanks.
