The Riton by Contessa 30mm Light Picatinny Rings in the 12mm height are a premium aluminum ring set for shooters who want aluminum’s weight savings and extra stability (Riton part no. XRC3012A23). Each ring is cut for a 30mm scope tube and rises 12mm for a center scope height of 1.06 inches. Riton builds them from 7075 aluminum alloy rather than 6061-T6 for added rigidity and durability. Dual recoil lugs spread recoil across a larger area, and machined grooves on the tube-facing surface help prevent slippage. They are a fit for a rifle with a mid-size objective that needs a bit more clearance than the 8mm version.

• Machined grooves on the tube-facing surface help prevent slippage.
