Weatherby PEAK 44 Picatinny Rail (JRAIL) Model 307 SA 20 MOA Scope Base Black

The Weatherby PEAK 44 Picatinny Rail (JRAIL) Model 307 SA 20 MOA Scope Base in black is a precision mounting solution engineered for shooters and hunters who demand optimal scope placement and versatility. Built from aerospace aluminum, this scope base features a distinctive rear cutout design that distinguishes it from conventional mounts, enabling proper eye relief and accommodation of large objective lenses—a critical advantage when pairing quality optics with rifles requiring precise zero retention.

The 20 MOA elevation offset integrated into this Picatinny rail base extends your effective shooting range, particularly valuable for long-range hunting and precision rifle applications where cartridges benefit from angled recoil plane compensation. The Model 307 variant accepts #8-40 screws and torques to 20 inch-pounds, ensuring secure, repeatable mounting that maintains zero through sustained shooting sessions. Compatibility with standard Picatinny and Weaver-style scope rings provides flexibility across your optics inventory, and the low-profile aluminum construction adds minimal weight—just 0.18 lbs—preserving your rifle's handling characteristics.

This Weatherby base suits bolt-action and semi-automatic platform users working with magnum calibers or precision setups where conventional bases compromise eye relief or force compromised cheek weld positions. Competitive shooters, long-range hunters, and rifle builders evaluating aftermarket mounting solutions will find this base addresses the engineering gap between budget mounts and heavy specialized systems. The rear cutout geometry is particularly practical for shooters running backup iron sights or magnified optics requiring clear sight picture without tube obstruction.
