TSR Series Rings are precision machined from aluminum billet with extremely tight tolerances for maximum scope-to-ring contact and secure recoil resistance.
The four-screw cap design allows for easy reticle alignment by tightening one side of the cap before the other, preventing scope rotation.
Designed to fit 30mm scope tubes, these medium-height rings (1.075") are made of steel and compatible with Mil-STD 1913 (Picatinny) bases.
