which bases are these???

[djtjr]

Can anyone tell me what bases these are? I need to order some rings and these came with the cooper I got. They look a bit like talleys but more narrow (less wide) and are well machined but I haven't seen them before.
Thanks in advance.

I would e-mail cooper to be sure but I would bet they are Talley's, I think that's all they use.

Since Cooper started in business in 1992, I have bought new Coopers with factory installed Warne, standard Leupold, and Talley bases. Your bases appear to be Warne. It is difficult to tell from the photo but they appear too narrow to be Weaver style bases. If so, I am not sure if Warne still makes these bases or rings to fit them. Warne does make Weaver style bases for the Cooper model 21. The earlier Warne bases are approx .45" wide where Weaver bases are approx .83" wide. The widths measured are at the point where the rings attach.

They look like the old style Warne bases as best I can tell in the photos. I'm sure I have several sets of new rings to fit them if they are Warnes. Shoot me a pm if I can help. Jim
