Riton Optics Contessa Features The Riton Optics Contessa 30mm Light Picatinny Rings are precision machined from 7075 aluminum alloy a material chosen for its strength-to-weight ratio in demanding rifle applications. This fixed ring design mounts directly to a Picatinny rail relying on integral double recoil stops to keep the rings from shifting forward or backward under repeated recoil impulses. A 12mm ring height is well suited to mounting scopes with moderate objective bells while keeping the optic s centerline reasonably low over the bore. That lower mounting height can improve cheek weld consistency for shooters who prefer a more traditional stock comb height. Machined to tight tolerances the rings are built to securely clamp a 30mm scope tube without introducing stress points that could affect long-term accuracy. Finished in Black with a matte coating the rings blend in with most rifle builds without drawing unwanted attention. At 5.8 inches overall length and just 3.4 ounces the ring set adds minimal bulk or weight to a rifle while providing a stable mounting platform. For shooters running a 30mm scope who want a durable lightweight Picatinny mounting option the Riton Optics Contessa rings are a solid choice for sale at GrabAGun.
