Weatherby 307 Builders Action Long Action Black

The Weatherby Model 307 Builders Action is a long-action, Remington 700-compatible platform intended for custom bolt-action rifle builds. It features a 2-lug bolt with tool-less takedown and a spiral-fluted bolt design with an M16 extractor, finished in Graphite Black Cerakote. Practical pairings for this action include custom hunting rifle builds and precision target shooting; an appropriate optic choice for these uses is the Vortex Viper PST Gen II 1-6×24 (commonly available under $1000) for close-to-mid-range precision and fast target acquisition.
