Weatherby J010001 Picatinny Rail 20 MOA Mark V Magnum 9-Lug Mount

The Weatherby J010001 Picatinny Rail transforms the Mark V Magnum 9-lug action into a precision long-range platform with its integrated 20 MOA cant. This black anodized aluminum rail replaces the factory Weaver-style mount with a full-length Picatinny system that accommodates modern optics and accessories.

What Makes This Different

Unlike standard zero-cant rails, this mount incorporates 20 minutes of angle built into the rail itself, extending effective range without adjusting scope turrets to their limits. The precision-machined aluminum construction maintains the Mark V's inherent accuracy while providing a rock-solid mounting platform. CNC manufacturing ensures consistent dimensions and proper headspace alignment across the receiver's 9-lug system.

Key Features

• Integrated 20 MOA cant maximizes long-range scope adjustment range
• Black anodized 6061-T6 aluminum construction resists corrosion and wear
• Full-length Picatinny rail accepts standard 1913 rings and accessories
• Direct replacement for factory Weaver mount on Mark V Magnum actions
• Precision-machined to maintain factory headspace and accuracy
• Multiple cross-slots provide flexible optic positioning options
• Low-profile design maintains clean rifle aesthetics

The 20 MOA forward cant proves particularly valuable for magnum cartridges where extreme range shots demand maximum scope elevation adjustment. Competition shooters and long-range hunters benefit from the additional 5.8 inches of elevation adjustment at 1000 yards compared to zero-cant mounts. The rail's full-length design distributes recoil forces across the entire receiver, reducing stress on individual mounting points during heavy magnum recoil.
