Talley Manufacturing Modern Sporting Scope Rings Features The Talley Modern Sporting Scope Rings are fully CNC machined from high grade lightweight aircraft aluminum giving the ring set the strength to hold zero under recoil without adding unnecessary weight to the rifle. Each ring is finished in a black anodize process beneath its Flat Dark Earth coating protecting the alloy from wear while keeping the rings matched to a tan or desert colored build. The 30mm tube diameter fits the wide range of modern optics built on that larger main tube and the Low ring height of .890 inch keeps the scope mounted close to the bore for a natural cheek weld. Because the rings meet MIL-STD-1913 Picatinny rail specifications they drop directly onto any rail cut to that standard without modification. At just 2.6 ounces for the pair the Talley Modern Sporting Scope Rings add almost nothing to the overall weight of a build which matters on a rifle already carrying a red dot or optic a light and a sling. The 2-piece design simplifies installation on an AR-pattern upper or any other rifle wearing an aftermarket Picatinny system and because lapping is not required out of the box shooters can mount an optic and get to zeroing right away. Altering or lapping the rings voids the warranty so they are intended to be installed as manufactured. Sold in pairs these American made rings give a modern sporting rifle a secure lightweight home for a 30mm optic at GrabAGun.
