TSR Series Rings are precision-machined from an aluminum billet to .0002" tolerances for maximum scope-to-ring contact and secure recoil resistance.
The rings feature a four-screw cap design for easy reticle alignment and a large clamp-nut for solid attachment to Mil-STD 1913 Picatinny bases.
Made from 7075-T651 Aluminum Alloy with a matte black, hard-anodized finish, these 35mm medium rings measure 1.185" from the base to the center of the ring.
