Dlask will make any barrel you want. I built an 8.5 on a wingmaster frame that I had Casey shorten and re thread the mag tube. Dlask made me an 8.5 barrel and a 14" barrel to fit the 8.5 frame. I don't think I had 1k$ into the whole setup. It was a nice range toy, but if I was to do it again I wouldn't bother with the 14" barrel, or I would make it just a little longer so a plus 2 extension wouldn't stick out the end. In the end the charm wore off, and although they do look nasty, they aren't anything special. I've heard that the interchangeable stocks on the mcs guns aren't that great, and they get wiggly after a while
