TSR Series Rings are precision machined from an aluminum billet to .0002" tolerances for maximum scope-to-ring contact and secure recoil resistance.
Features a four-screw cap design for easy reticle alignment and a large clamp-nut for secure attachment to Mil-STD 1913 (Picatinny) bases.
Constructed from 7075-T651 Aluminum Alloy with a matte black, hard anodized finish, the rings are 5/8" wide and the low height is measured at .785" from the base to the center of the ring.
