The Weatherby Model 307 Builders Action (Weatherby part no. 3WBSM) is a bare bolt-action platform built for shooters assembling a custom short-magnum rifle from the ground up. Weatherby machines the action around a 2-lug cylindrical bolt with a spiral-fluted body, a reliable M16-style extractor, and tool-less takedown for easy maintenance. The action is drilled and tapped for scope mounts or a Picatinny rail and is compatible with most aftermarket Remington 700-pattern stocks, triggers, and bottom metal, giving builders wide latitude to finish the rifle to their own specification.
