Leupold Mark 4 Rings

The Mark 4 ring is one of the longest-serving tactical rings on the market, and its reputation is earned. Built on Leupold's proven cross-slot design, it clamps to any Picatinny or Weaver rail and holds zero through recoil, heat, and hard use. Leupold offers the line in both machined steel and 7075-T6 aluminum depending on model, so a shooter can pick the heavier, bombproof steel for a duty rifle or the lighter aluminum for a hunting build. Four cap screws per ring, medium through super-high heights, and 1 inch or 30mm tube sizes cover the conventional optics that bolt guns and patrol rifles run. It is the safe, proven mid-tier choice when a shooter wants a known quantity rather than a boutique billet ring.
