Riton Optics 34mm Riflescope Rings Set of 2 Black High. Constructed from 6061-T6 aircraft-grade aluminum Riton Rings are robust and trustworthy drawing on the lightweight easy handling of aluminum while still being rigid and solid. The inside of the rings are lined with a thin cushion pad that improves contact with the scope and helps to lock the optic in place while a single cross-rail recoil lug keeps the ring from moving on your base or rail.
