You know I had a pair of these on a rimfire a while back just because I wanted to get up and running as fast and as cheap as possible. If I had to guess I would say they were extruded aluminum and they just get chopped into slices and a couple holes drilled tapped and counter sunk. Only 12 bucks for a pair on midway. I of course, immediately dismissed them as being only decent at best.
Recently I got a pair for a light weight .308 bolt gun and I have to say, they are holding up very nicely to the recoil. The alumunim grips the scope very firmly and are more rigid than you would guess. Besides the usual PITA of mounting any scope in a vertical split ring design, my only gripe is that my Wheeler Engineering torque wrench did not come with the corresponding allen hex bit for these rings. I had to ballpark it using the supplied L shaped wrench (I hate doing that).
