Weatherby Mark V Frontier 378 WBY Mag 24" 3+1 Bolt-Action Rifle

The Weatherby Mark V Frontier is a full-size bolt-action hunting rifle chambered in the legendary 378 Weatherby Magnum cartridge. Built around the proven Mark V action, the Frontier pairs Weatherby's magnum heritage with a streamlined, hunting-ready configuration aimed at hunters who pursue the largest game on the planet.

Its 24-inch barrel is finished in Graphite Black Cerakote for corrosion resistance in harsh environments and is factory-threaded at the muzzle for suppressor or accessory installation. A Weatherby Accubrake ST muzzle brake adds roughly two inches of overall barrel length while taming magnum recoil and helping keep the optic steady for follow-up shots. The barrel uses a 1:12" twist rate.

The steel receiver is finished in matching Graphite Black Cerakote and is drilled and tapped for scope base installation, providing a solid mounting platform. At the heart of the action, an adjustable TriggerTech trigger delivers a crisp, clean break with user-tunable pull weight. The rifle ships with iron sights installed and a 3+1 capacity.

The classic Monte Carlo stock is sculpted from oiled walnut and finished in a warm brown tone, offering traditional Weatherby styling with a comfortable cheek weld. At 44.25" overall and 8.70 lbs, the Mark V Frontier balances magnum-class performance with manageable carry weight in the field, making it equally at home on a safari, an elk hunt, or an Alaskan brown bear pursuit.
