Osuma scopemounts are made from high-grade aluminum and manufactured with state of the art tools and methods. They are dimensionally extremely precise and made with true professional skill. The surface is anodized for durability.
We provide rings for our own bases and for Optilock base and Picatinny rail and for every main tube size from 1” to 40mm. We’ve paid extra attention to details such as the screws used to combine the two halves of the rings. Our rings can be opened and tightened without worrying that the screw heads wear out.
