I came up with a new scope its one of the old bushnell phantom 2.5x.I got this thing for nearly nothing it was still in the box looks new but base was not in the box.I think B Square made the base for bushnell/ Thompson years ago.Any idea where i could find a base .I can make one if i can't find one but buying one would be alot easier.

If this is the old rail type mount you are referring to, they surface on e-bay pretty often. That may be your best bet as these are seldom found in gunshops nowadays.

Bobby thanks for reply i found one on ebay.I put my bid in don't know what the thing will bring.
