Leupold Mark 4 35mm High Aluminum Rings | FDE Picatinny Scope Mounts LU185237

The Leupold Mark 4 35mm High Aluminum rings in FDE are precision-engineered Picatinny mounts built for the absolute security of your 35mm optics. In professional shooting, the most common point of failure is a shifting zero caused by cheap materials or clamp slippage under heavy recoil. These rings eliminate that risk by creating a rock-solid, high-torque interface that keeps your glass perfectly aligned, shot after shot.

The real strength of this system lies in the use of 7075-T651 aluminum. Unlike softer 6061 alloys, this aerospace-grade material handles a 65 in-lb clamp load without the threads stripping or the metal deforming. This massive increase in clamping force means your optic stays put during violent recoil cycles, while the ultra-tight machining tolerances ensure the rings don't pinch or distort your scope tube.

By combining CNC-machined 7075-T651 aluminum with a rugged Picatinny cross-slot design, Leupold has created a mounting system that simply does not shift. The 1.06-inch centerline height provides the perfect lift for large-objective scopes to clear your rail, while the FDE hardcoat anodizing protects against harsh field wear and prevents corrosion between the rings and your scope.

Key Features

• 7075-T651 Aluminum Construction | Aerospace-grade alloy provides superior tensile strength over standard 6061, allowing for higher torque loads without thread failure.
• 65 in-lb Keeper Clamp Rating | Combined with a precision cross-slot Picatinny interface, this high-torque capacity ensures rock-solid, recoil-resistant zero retention.
• Hardcoat Anodized FDE Finish | A non-conductive oxide layer protects against surface wear and galvanic corrosion at critical optic contact points.
• 1.06-inch Optical Centerline | The high-profile design provides the necessary lift to clear large objective lenses on heavy-barrel or railed rifle platforms.
