Weatherby PEAK 44 Picatinny Rail Features The rear cutout is the defining feature of this JRail design opening up clearance so shooters can mount low rings for a proper cheek weld while still running large objective scopes that would otherwise crowd the receiver bridge. Machined from aerospace-grade aluminum and finished in a matte black anodized coating the rail resists wear and corrosion while keeping added weight to a minimum on the rifle. The 20 MOA of built-in elevation compensation shifts the scope s usable adjustment range toward drop compensation which is exactly what long-range shooters need when reaching past a few hundred yards. Installation is straightforward with the included mounting hardware and T10 Torx bit and Weatherby specifies a 20 in/lb torque setting for the mounting screws to keep the base secure without over-stressing the receiver. Because it fits both Picatinny and Weaver-style rings shooters have flexibility in choosing ring height and brand when building out their optic setup. This base is purpose-fit to the Model 307 short action giving Model 307 owners a precise factory-matched foundation for their optic rather than relying on an aftermarket universal rail.
