This version permits mounting on Picatinny rails and will position the center of the scope tube 1.45" above the base. It also uses exceptional Grade 8 fasteners for securing the scope and each ring is vibratory tumbled and hand bead blasted.
Fantastic rings, worth way more then the asking price. Very light and heavy duty.
Great set of rings, I used them with a vortex Viper PST 5-25 and was only off bullseye by only 3" at 75 yards. That was just leveling and tightening it, with NO BORESIGHTING. I think these are just as good as rings costing much more.
