Just like every product I have purchased from IOR Valdada these rings exceeded my expectation.
These rings are .250" from base to bottom of ring curve. 7075 alloy construction. Steel hardware: cross bolt, clamp and nut. High precision machined with pride in the USA. Excellent finish.
Very strong, wider than a standard tactical ring (22 mm or 7/8) yet, light weight and easy to mount. Torx screws on top of ring cap need to be tightened to 22-25 inch/lbs. Hex nut at the base use 55 inch/lbs.
Square cross bolt, eliminates any chance the ring will move or slide on the Picatinny rail.
Made in USA
