30mm Tactical 6-Hole Rings High Picatinny Style Matte Finish by WEAVER Weaver's popular 6-Hole Tactical Rings just got the Picatinny treatment. These new rings feature the same six screws for max security and clamping pressure but get serious upgrades for LE and military use. An improved Picatinny crossbolt design (from Weaver® to Picatinny spec) and Type-3 hard coat anodized finish and no strip/slip Torx screws and an increased number of height options make these new 6-hole rings the go-to mounts for all Tactical Precision rifles. Will accommodate up to a 50mm objective.
