Machined from 7075-T6 aluminum in serialized pairs to the most exacting standards in the industry, Seekins Scope Rings never need to be lapped or altered in any way. Scope Rings are .8″ wide (4 screw cap) to provide more clamping surface area than any other ring on the market. Smooth edges and radiuses make Seekins Scope rings snag-free and will not hang up when deploying from drag bags or scabbards. Ring sets 1.26″ and taller have weight reduction machining in the bottom of the ring body. All rings are Type III Hardcoat Anodized matte black for a durable, non-glare finish. Built to the 1913 Picatinny specification, Seekins Precision Scope Rings have a center lug machined directly into the bottom. This integral, flat recoil lug is far superior to cross-bolt lug designs and fits precisely into Picatinny slots with minimal clearance. For maximum torque and strength, Grade 8 T-25 Torx fasteners are used that will not strip out while being tightened to the appropriate specification.
