Weatherby 307 Alpine ST: Modern Precision Meets Lightweight Design
The Alpine ST represents Weatherby's commitment to evolving rifle design for today's shooter. Built on the new Model 307 bolt-action platform, this rifle bridges the gap between Weatherby's historic Mark V and Vanguard lineups while offering something distinctly modern.
The Model 307 Action
The heart of this rifle is Weatherby's 2-lug, fully cylindrical action—a design that prioritizes compatibility with the modern aftermarket ecosystem. Whether you're looking to upgrade triggers, stocks, rails, or mounts, the Model 307 accepts a vast array of accessories without compromise.
Lightweight Performance
Weatherbys partnership with PEAK 44 resulted in the Bastion stock, a purpose-built platform that weighs just 24 ounces. This ultra-light construction doesn't sacrifice functionality:
- 3D-Hex recoil pad reduces felt recoil and improves shooter comfort
- Spiral-fluted barrel delivers unmatched accuracy while saving weight
- Accubrake ST muzzle brake further mitigates recoil impulse
- Total rifle weight: 6.3 lbs—ideal for hunters and precision shooters who value mobility
