John,
I have done it on a few of my Hawken and Renegade barrels using the T/C rail mount scopes. T/C has a base # 9754 for the 1" width barrels, and I don't remember the part number for the 15/16" barrels. However they will require a couple of extra holes be drilled and tapped into the barrel to use together with the rear sight holes already there.
