Ruffs Precision Precision Scope Rings Features The Ruffs Precision Precision scope rings are built around a visible built-in level that the shooter can reference from their normal shooting position with the non-dominant eye. This lets a shooter catch cant before the shot breaks rather than discovering it downrange and it removes the need for balancing a separate bubble level on the receiver during mounting. The 6061-T6 aluminum ring body and cap keep the rings light while the 303 stainless steel crossbolt and nut hold everything secure under recoil. An alignment lug ensures the cap and base line up correctly during cap screw installation reducing the chance of a misaligned mount. Sized for a 34mm tube in a medium 1.00 height these rings fit a wide range of modern riflescopes while keeping the optic at a workable sight line. Recommended torque values of 18 in/lbs for cap screws and 45 in/lbs for the crossbolt give installers a clear target for a secure factory-correct mount. Made proudly in the USA the rings weigh just 4.4 oz for the medium height keeping added weight on the rifle to a minimum. Shooters mounting precision glass on a 34mm tube will appreciate the built-in reference level for confirming a true repeatable zero.
