Ruffs Precision Precision Features The Ruffs Precision Precision ring set is built around a co-linear bubble level machined directly into the ring body giving shooters a direct visual reference to the rifle s cant during the scope mounting process. Because the level sits within the ring body itself it remains visible from the normal shooting position using the shooter s non-dominant eye eliminating the need for multiple small levels and the balancing act that typically comes with them. The ring body and cap are machined from 6061-T6 aluminum a material chosen for its strength-to-weight balance in precision mounting applications. A 303 stainless steel half-inch cross bolt and nut provide a secure corrosion-resistant clamping system for the 30mm tube. An alignment lug built into the design ensures the cap and base stay properly aligned during cap screw installation helping shooters achieve consistent torque and ring alignment every time. Recommended torque values of 18 in-lbs for the cap screws and 45 in-lbs for the cross bolt give shooters a clear benchmark for proper installation. At a high ring height of 1.25 inches and roughly 5 ounces for the set the rings suit larger objective scopes that need extra clearance over the barrel. Proudly made in the USA the Ruffs Precision Precision ring set is built for shooters who demand both precision and convenience in their mounting hardware available for sale at GrabAGun.
