The Weatherby Mark V Backcountry 2.0 Carbon in 30-378 Wby Mag is a left-hand rifle engineered for hunters who refuse to compromise between firepower and packability. Built around Weatherby's legendary Mark V action paired with a tensioned carbon fiber barrel, this 28-inch left-handed rifle delivers the velocity and flat trajectory of a belted magnum in a surprisingly lightweight platform—ideal for alpine hunts, backcountry expeditions, and long-range mountain shooting where every ounce matters.
What sets the Backcountry 2.0 Carbon apart is its obsessive attention to weight reduction without sacrificing accuracy or durability. The carbon fiber barrel carries Weatherby's track record for precision (a Mark V Carbonmark with this barrel set an internal accuracy benchmark of 0.06 inches at 100 yards with factory ammunition), while the Peak 44 Blacktooth stock—the lightest production carbon fiber stock available—shaves pounds without compromising rigidity or field ergonomics. The second-generation 3DHEX recoil pad, a 3D-printed system with interlocking voids, absorbs the sharp bite of magnum recoil by expanding the impulse over time, making follow-up shots more manageable.
The rifle is finished in Patriot Brown Cerakote across all action and barrel metal, with a matching brown and green sponge-pattern carbon stock designed to break up your outline in open country. The titanium Accubrake ST muzzle brake features 30 symmetrically-spaced ports to further tame recoil, while spiral fluting on the bolt body and a lightweight aluminum skeletonized handle keep unnecessary weight where it doesn't belong. Left-hand shooters get the full feature set—this is a purpose-built rifle, not an afterthought.
Whether you're glassing ridge lines above timberline or setting up for a long-range validation shot, the Mark V Backcountry 2.0 Carbon delivers magnum performance in a rifle light enough to carry all day.

This particular rifle is configured for left-hand shooters. Contact us to inquire about right-hand versions or other Mark V Backcountry 2.0 options.
The tensioned carbon fiber barrel reduces overall weight while maintaining the accuracy reputation Weatherby has built with this system. The barrel is lighter than steel without compromising rigidity, helping keep total rifle weight at 6.6 lbs—critical for backcountry and mountain hunting where you're carrying the rifle all day.
The 3DHEX is a 3D-printed pad with interlocking voids inside. As recoil occurs, these voids progressively collapse, which stretches the recoil impulse over a longer time period. This reduces the sharp spike of recoil you feel, making magnum chamberings like the 30-378 Wby much more pleasant to shoot, especially during practice or extended range sessions.
