Talley Manufacturing Modern Sporting Scope Rings Features The Talley Modern Sporting Scope Rings are fully CNC machined from high grade lightweight aircraft aluminum giving shooters a rigid and precise mounting solution without adding unnecessary weight to the rifle. Designed to meet MIL-STD-1913 Picatinny rail specifications these rings work on any rail built to that standard whether it is an aftermarket Picatinny rail on a modern sporting rifle or a different rifle platform entirely. Sold in a high ring height with an actual measured height of 1.09 inches these rings are sized for a 30mm scope tube a common diameter among modern riflescopes. Talley notes that lapping is not required on these rings and attempting to do so will void the warranty reflecting the precision of their machining process. Finished in Flat Dark Earth with a black anodize base finish these rings are built to complement modern sporting rifle builds that favor earth tone furniture and coatings. At just 3.4 ounces for the pair the rings add minimal weight to a rifle setup which matters to shooters who are weight conscious about their overall build. Sold in pairs as is standard for scope rings these Talley mounts are American made and have grown in popularity as a cost effective alternative to more expensive ring systems. For anyone building or upgrading an AR15 pattern rifle or another Picatinny equipped rifle these Talley Modern Sporting rings offer a dependable lightweight mounting solution.
