Aircraft-grade aluminum scope rings feature self-adjusting clamping legs that fit 3⁄8" or European 11mm dovetail mounts found on many bolt-action rimfire rifles. Each leg moves equally as the clamping screws are tightened to keep the scope centered on the rail. Clamping screws also fit into pre-drilled holes to equally spread the legs to easily slip over oversized rails. 200 Series fits 1" scopes and 300 Series fits 30mm scopes. Available as a one-piece cantilever mount with a 2.4" offset, a pair of scope rings, or as a pair of one standard and one offset ring with a 1.3" offset. Ring pairs available as either single, or double top strap. Single-strap rings measure .6" front-to-back. Double strap rings measure 1" front-to back. Height measured from the top of the base to the bottom of the scope tube. Hardcoat anodized, matte black or natural silver finish.
