Lately bought these odd ones…

I mean a 1960’s 1.5x optic rig, $10! The Millett S-ight O-ver S-cope rings didn’t catch on. But again, $20 for 1” rings. (eBay) These are odd, for a 870 rib. But the tops fit on other sets I have. I could put a red dot on a shotgun.

You must have a turret that does not obscure the pistol sights. Trick kit on the Reeder TC barrels with no irons otherwise.
