I'm stumped. They're not dovetail and certainty not Weaver or Picatinny. This little guy came off a Thompson Center Contender rifle barrel (Texas Contender by Kendrick). My friends and I are at a loss to what kind of base this is and what rings go on it.
It's circular with two screws with points at either end to secure the rings. I figured I'll toss it up to Calgunners before going to the Gunsmith.
