I also have a TC/CVA barrel .50 caliber,15/16" across the flats . $175.00 shipped.It's one that I built for myself and is more accurate than either one of my boys TC Hawkens. As for my background,I am a retired machinist/toolmaker/gunsmith with AADegree in Gunsmithing from Trinidad. Michael
J.m. it needs to be a tc so as to drop into my existing tc. I have a good 45 barrel and a 54 barrel but want to fill in the gap with a 50. I prefer to rebore a tc barrel to 50 rather than go with a tc 50.
