Key Features
- Sendero-Profile Fluted Barrel: The 24-inch barrel is fluted to reduce weight while maintaining stiffness for consistent harmonics. Why it matters: Less weight on the carry, more accuracy on the clock — critical for field shooting and match stages.
- 300 WSM Short Action: The 300 Winchester Short Magnum fits in a compact action without sacrificing velocity. Why it matters: Faster cycling, shorter bolt throw, and the same terminal performance as a full-length .300 Win Mag.
- Larue Tactical Trigger (MBT-2S): Two-stage trigger with a crisp 4.5-pound break. Why it matters: Predictable let-off reduces shooter error and keeps groups tight.
- FDE Cerakote Finish: Flat Dark Earth coating applied over the entire rifle. Why it matters: Corrosion resistance and low-glare surface for tactical and hunting environments.
- Right-Hand Action with 3+1 Capacity: Detachable box magazine holds three rounds plus one in the chamber. Why it matters: Enough capacity for hunting or precision competition without excess bulk.

Law enforcement precision marksmen, military snipers, and serious long-range shooters who need a rifle that performs under field conditions. If you run a short-action chassis and want a magnum cartridge with flat trajectory and retained energy at 1000 yards, this is your build.
