Leupold built the Mark 4 line to be the backbone of their mounting systems, and these 30mm Super High rings earn that reputation. Machined from solid aircraft-grade aluminum with a low-glare matte black finish, they fit any Picatinny rail and any scope running a 30mm main tube. The Super High configuration gives you a 1.40 inch ring height, which is exactly what you want when a large objective bell needs to clear the rail without crowding your bolt or rail covers.
These rings use Leupold's proven cross-slot design, machined to tight tolerances from solid stock rather than cast. That matters when you're mounting a heavy tactical or long-range optic and need the mount to hold zero through recoil and rough handling. The two-piece layout makes leveling and alignment straightforward, and the aluminum build keeps weight down to around 5.2 ounces for the pair, so you're adding strength without piling on ounces.
Leupold spec's the keeper clamp torque at 65 in-lbs and the ring top screws at 28 in-lbs, so a quality torque wrench will get you a secure, consistent clamp without overdoing it. The Super High height is generally the pick for scopes with 50mm or larger objectives, where medium and high rings just don't give enough clearance. If you're running a big-bell precision scope on an AR, bolt gun, or any flat-top with a Picatinny rail, these put the optic right where it needs to sit.
It's a no-nonsense mount from a company that's been making dependable optics gear for generations. If you already trust Leupold glass, the Mark 4 rings are a natural match to hold it steady.
These rings are built for scopes with a 30mm main tube and mount to any Picatinny or Picatinny-style rail. That covers most AR and MSR platforms, flat-top uppers, and bolt guns running a Picatinny base. Double-check that your optic is a true 30mm tube before ordering.
Super High rings give you a 1.40 inch ring height, which is the extra clearance you need for large objective scopes, typically 50mm and up. If your objective bell is bumping the rail or rail accessories with shorter rings, Super High solves that. For smaller objectives, a medium or high ring is usually the better fit for a lower, more natural cheek weld.
Leupold lists the keeper clamp torque at 65 in-lbs and the ring top screws at 28 in-lbs. A good torque wrench is worth using here so you get a secure clamp without crushing the tube or stripping threads. Snug things down evenly across the screws for the best hold.
This model, part number 57555, is machined from solid aircraft-grade aluminum, which keeps the pair light at about 5.2 ounces while staying plenty strong. Leupold also offers Mark 4 rings in steel for folks who want the added mass. For most setups, the aluminum version holds zero just fine and shaves weight off the build.
