Description
The Leupold Mark 4 30mm High Matte rings are the kind of mount you set once and forget about. Machined from aluminum to tight tolerances, this pair rides on Leupold's cross-slot design and clamps directly to a Picatinny rail, giving your 30mm tube optic a rock-solid home that doesn't shift when the gun goes off. The high height gives you 1.06 inches of optical centerline, which is the sweet spot for clearing a larger objective bell or getting the scope up where you need it for a comfortable cheek weld.
What Sets the Mark 4 Rings Apart
Mark 4 is the top of Leupold's ring lineup, and the fit and finish show it. The matte black anodized finish keeps glare down and shrugs off field abuse, and the cross-slot bars drop into the rail recoil grooves so nothing walks forward under repeated heavy recoil. This set accommodates both the standard 6-48 screw and the beefier oversized 8-40 screw, so it's at home on hard-kicking rifles where lesser rings start to loosen up.
Mounting the 30mm High Matte Rings
Setup is straightforward. The keeper clamps torque to 65 in-lbs against the rail, and the ring top screws spec out at 28 in-lbs, so a decent torque wrench gets you repeatable, even clamping pressure every time. They work on any Picatinny-style rail and pair up nicely with Leupold PRW and QRW bases if that's your setup.
At right around 4.4 ounces for the pair, these keep weight sensible without giving up strength. Whether you're building a precision rig, a dedicated hunting rifle, or a tactical setup, the Mark 4 30mm High rings are a dependable, no-drama way to lock a quality scope down and keep it there. Made in the USA and backed by Leupold's lifetime guarantee.

Frequently Asked Questions
What size optic do the Mark 4 30mm High rings fit?
These rings are built for riflescopes with a 30mm main tube. The high height gives you 1.06 inches of optical centerline above the rail, which is ideal for clearing larger objective bells or getting the scope up for a solid cheek weld.
Do the Leupold Mark 4 rings work on a standard Picatinny rail?
Yes. The cross-slot bars drop into the recoil grooves of any Picatinny-style rail for a secure, repeatable fit. They also pair up with Leupold PRW and QRW bases if that's your setup.
What torque should I use when mounting these rings?
Leupold specs the keeper clamps at 65 in-lbs against the rail and the ring top screws at 28 in-lbs. A quality torque wrench makes it easy to get even, repeatable clamping pressure, which helps keep your zero consistent.
Are these a pair of rings or a base and ring combo?
This is a matched pair of two rings. They mount directly to a Picatinny rail, so you don't need a separate base as long as your rifle already has a rail.
