The Leupold Mark 4 rings are extremely rugged and accurately machined rings intended to mount 1″, 30 mm or 34 mm scopes onto Weaver or MIL-STD 1913 Picatinny rails. They come in Medium, High and Super High configurations to suit even the largest objective scopes. The Mark 4 ring is extensively used by the US military and is certified for the highest recoil applications including .50BMG. To keep weight down, 7075 T-651 aluminum versions are available as an alternative to the original 11L17 steel. The Mk 4 rings are either blued or mil spec. hard anodized in a matte black finish and clamp down with 8-40 Torx screws using the wrench included. Large hex nuts enable easy clamping of the Mark 4 ring onto the rail for ultra solid mounting and reliable operation.
