The Weatherby Model 307 Short Action Builder’s Action (brand part no. 3WBSS) is a bare, short-action rifle receiver finished in Graphite Black Cerakote, sold on its own for custom rifle builds. Weatherby designed the Model 307 as its first new action in over 50 years, built specifically to accept the huge range of aftermarket stocks, triggers, rails, mounts, and bottom metal already on the market. The 2-lug bolt features a tool-less takedown for fast, easy disassembly and cleaning, and every action carries the same precision machining Weatherby has built its reputation on since 1945. As a bare receiver, this action is the serialized firearm under federal law, giving builders a blank-slate foundation to assemble a fully custom short-action rifle.
