There is only 1 person who can get the "real deal" barrels, and thats the sub-contractor who builds them for Crane, and he doesnt sell them to anyone other than Uncle Sam. There are a few of his uppers in the general publics hands though. The barrels I sell and the barrels MSTN sell are just copies, both turned from 1:7 blanks to the same SPR specs buy CLE (and no, CLE does not turn the real barrels), and KG Coated at the same place. The WOA barrel is a Wilson blank, and MSTN offers a Douglas. If you want a Douglas I can offer that, but people are very happy with the cost/performance of the Wilson. I'm not sure how long ago Lawman734 bought an Adco barrel; the first maybe 3 or 4 barrels I sold were not the correct contour, but they are today.
