Weatherby 307 Builders Action Long Magnum Black 1-1/16″”-16 Thread Pitch

The Weatherby Model 307 Builders Action offers a versatile platform for creating a custom bolt-action rifle. Designed with a 2-lug cylindrical bolt, it features a spiral-fluted design, a reliable M16 extractor, and tool-less takedown for ease of maintenance. Compatible with most aftermarket Remington 700 accessories, including stocks, triggers, and bottom metals, this action allows builders the flexibility to craft a rifle tailored to their needs. Tapped for scope mounts or a Picatinny rail, the Model 307 is ready for customization and built with the precision craftsmanship that Weatherby is known for since 1945.
