jrkrk,
I put the T/C rail mount bases on a few T/C Hawken and Renegade barrels and share a LER T/C 2.5 rail mount lighted reticule scope between them and a Contender barrel which also wears a rail mount base.
The bases require an additional hole to be drilled and tapped in addition to the existing holes for the rear sight.
Contact me by e-mail and I will look up the part number for the base and scope. There are different part numbers for the 1" and 15/16" barrels. Although T/C sells the bases, you can find them cheaper at a number of the usual places for T/C stuff.
