Ruffs Precision Precision Scope Rings Features The Ruffs Precision Precision scope rings pair a 6061-T6 aluminum ring body and cap with a 303 stainless steel cross bolt and nut giving the mount the strength to hold a 34mm optic securely under heavy recoil. An alignment lug ensures the cap and base stay registered during cap screw installation so clamping pressure is applied evenly around the tube. The low .885 ring height keeps the optic close to the bore for a more natural cheek weld on most rifle stocks. Recommended torque values of 18 in-lbs on the cap screws and 45 in-lbs on the cross bolt give shooters a repeatable factory-specified mounting process. The built-in co-linear bubble level is the signature feature of this design staying visible from the shooting position with the non-dominant eye for a quick cant check right before the shot. That eliminates the need for a separate add-on bubble level and the awkward balancing act of checking it mid-position. At 3.9 oz for the low-height pair the rings add minimal weight to a precision rifle build. Proudly made in the USA the Ruffs Precision Precision rings are a straightforward upgrade for shooters who want a built-in reference for cant on every shot.
