Weatherby Wthby J010004 307 SA 20 MOA Picatinny Rail for Precision Rifles

The Weatherby PEAK 44 Picatinny rail is a precision rifle scope base engineered for shooters who run demanding setups on Weatherby 307 actions. This 20 MOA angled rail mounts directly to your receiver, tilting your scope upward to extend effective long-range capability without relying solely on turret elevation—a real advantage for extended-distance hunting and precision shooting. The aerospace-grade aluminum construction keeps weight minimal while delivering the rigidity required for repeatable accuracy.

What makes this rail stand out is its rear cutout design. That cutout is no gimmick—it does something practical: it allows you to mount lower rings and position your scope closer to the barrel, giving you better eye relief options while still clearing large objective lenses. That matters when you're running magnum optics or trying to get a genuinely comfortable sight picture. The rail accepts standard Picatinny and Weaver-pattern rings, so you're not locked into Weatherby rings alone.

This is the 307 SA (short action) variant, and it ships with the hardware you need—#8-40 screws and a T10 Torx bit for installation. Weatherby specs 20 inch-pounds of torque for those fasteners, so there's no guesswork when bolting it down.

Frequently Asked Questions

Will this rail work with my Weatherby Vanguard or Mark V rifle?

No. This is the 307 SA variant, designed specifically for Weatherby 307 short-action rifles. Weatherby makes separate rail models for Vanguard and Mark V actions, which use different fastener sizes (#6-48 screws on those models). Check your action type before ordering.

What scope rings do I need?

Any rings with standard Picatinny or Weaver-pattern bases will work. You're not limited to Weatherby-branded rings, so you have flexibility in choosing quality rings that match your budget and scope diameter.

What does the 20 MOA angle do?

The 20 MOA tilt tilts your scope upward slightly, giving you more elevation adjustment range in your scope's turrets. On a long-range rifle, this lets you dial elevation for distant targets without maxing out your scope's internal adjustment, extending your practical shooting distance.

What's included in the box?

The rail ships with the mounting screws (#8-40) and a T10 Torx bit for installation. You'll need to supply your own rings and scope.
