Osuma scopes are made from high-grade aluminium, 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, as well as for Optilock bases and Picatinny and Tikka rails; 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.
