Key Features
Weatherby 307 Action
The Weatherby 307 action forms the core of this rifle, featuring a two-lug, 90-degree bolt throw for rapid cycling and a Rem 700-compatible footprint for broad aftermarket component compatibility. Engineered with an integral recoil lug and strategic gas vents, this action prioritizes structural rigidity, consistent lockup, and enhanced shooter safety under diverse operational conditions.
MDT HNT26 Carbon Fiber Chassis System
The MDT HNT26 chassis is integral to the Alpine MDT Carbon’s performance profile. Constructed from aerospace-grade carbon fiber and magnesium, this chassis significantly reduces overall rifle weight without compromising structural integrity or accuracy. Its modular design permits ergonomic adjustments for length of pull and comb height, optimizing shooter interface. M-LOK attachment points facilitate the integration of accessories, ensuring functional adaptability in the field.
Fluted Steel Barrel
This rifle incorporates a 22-inch fluted steel barrel, finished with Graphite Black Cerakote. The fluting strategy reduces barrel weight and increases surface area for enhanced heat dissipation, mitigating thermal drift during extended firing sequences. The barrel is threaded 5/8×24 TPI, prepared for the direct attachment of muzzle devices, suppressors, or brakes, thereby managing recoil and optimizing sound suppression.
280 Ackley Improved Caliber
The 280 Ackley Improved cartridge delivers superior ballistic performance, offering increased velocity and flatter trajectories compared to its parent cartridge. This translates to extended effective range and enhanced terminal performance on game, making it a highly efficient and versatile caliber for a variety of shooting applications.
Performance Guarantee
The Weatherby 307 Alpine MDT Carbon is backed by the manufacturer’s SUB-MOA guarantee, ensuring .99-inch or tighter groups at 100 yards with premium ammunition. This guarantee underscores the rifle’s inherent precision and manufacturing consistency, providing a verified performance benchmark.
TriggerTech Trigger
An adjustable TriggerTech trigger unit provides a crisp, predictable break, facilitating precise shot placement. The trigger’s consistent pull weight and minimal overtravel contribute directly to shooter confidence and the rifle’s overall accuracy potential.
