TSR-W SL (Super-Low) Series Rings are designed to provide a mounting solution for special applications that require an extremely low mounting height. The rings are precisely machined with tolerances held to .0002'', ensuring maximum scope/ring contact. Not only do these rings hold the scope securely against recoil, but their four-screw cap allows you to align the reticle and tighten the left and right sides of the cap separately without the scope rotating. The radiused edges and corners not only help prevent snagging, but they also provide an attractive appearance. Plus, the large clamp-nut lets you torque rings to Weaver-style or Mil-STD 1913 (Picatinny) bases. The ring's height is measured from the top of the base to the center of the ring.
