SP rings are built like a tank to withstand a lifetimes worth of punishment and designed to never allow your scope to move. At .8" wide (4 screw version) and 1" wide (6 screw version) they have more clamping surface area than any other ring on the market. You can toss away the flimsy Allan wrench your used to using as we use off the shelf T25 Torx, grade 8 screws that will never strip. SP's rings are built in accordance with the Picatinny 1913 specification and fit the cross slots with minimal clearance. Available in 1”, 30mm, 34mm, and 35mm tube sizes. Our rings feature slim lines for a snag free deployment out of scabbards and drag bags. 1.25" and higher ring sets are lightened with a pocket on the ring bottom. Precisely machined pairs are serialized, built from Billet 7075t-6 alloy and coated with Type III Class 2 Hardcoat Anodize.
