Weatherby 307 Adventure SD 6.5-300 Weatherby Magnum Bolt Action Rifle
The KFF Defense team presents the Weatherby 307 Adventure SD, a precision bolt-action rifle engineered for the discerning long-range hunter and competitive shooter. Chambered in 6.5-300 Weatherby Magnum, this platform delivers extreme velocity and a flat trajectory, optimizing engagement capability across extended distances. The Adventure SD variant is purpose-built for rugged field utility, integrating features that enhance durability, recoil mitigation, and consistent accuracy in diverse operational environments.
Key Features
- **Weatherby 307 Action:** The core of this rifle is the Weatherby 307 action, meticulously crafted to a Remington 700 footprint, ensuring broad aftermarket component compatibility while maintaining KFF Defense’s exacting standards for reliability and precision. This action provides a robust and repeatable foundation for consistent performance.
- **Precision Barrel:** A 26-inch cold hammer-forged barrel is integral to the rifle’s precision. The fluted profile reduces weight and enhances heat dissipation, critical for maintaining accuracy during sustained fire. The barrel is threaded (common configurations are 5/8×24 TPI, confirming suppressor compatibility) and includes a muzzle protector, allowing for direct integration of muzzle devices or suppressors.
- **Ergonomic Composite Stock:** The rifle features a lightweight, durable composite stock, designed for optimal ergonomics and all-weather performance. Its structure effectively mitigates felt recoil, enhancing shooter comfort and follow-up shot capability. The stock’s rigidity contributes directly to shot consistency.
- **Adjustable Trigger:** An advanced, user-adjustable trigger mechanism ensures a crisp, clean break, facilitating precise shot placement. This feature allows the shooter to fine-tune trigger pull to individual preference, thereby optimizing accuracy potential.
- **Corrosion-Resistant Finish:** All critical metal components are treated with a durable, corrosion-resistant finish (e.g., Cerakote), providing superior protection against the elements encountered in demanding field conditions.
