About this product
What is the Weatherby Mark V Backcountry 2.0 Carbon 30-378 Wby Mag 26″? It's a premium lightweight magnum rifle built around Weatherby's steel Mark V action with a tensioned carbon fiber-wrapped barrel and Peak 44 Blacktooth carbon stock, weighing just 6.6 pounds while delivering full-power .30-378 Weatherby Magnum ballistics. This rifle represents Weatherby's commitment to merging magnum performance with backcountry portability through advanced materials engineering.
What is the Weatherby Mark V Backcountry 2.0 Carbon used for?
This rifle is designed for long-range hunting in rugged terrain where every ounce matters. The .30-378 Weatherby Magnum cartridge delivers exceptional downrange energy for elk, moose, and bear at distances exceeding 400 yards, while the carbon construction keeps the total package weight under 7 pounds for extended carries through mountain country.
How does the Weatherby Mark V Backcountry 2.0 Carbon compare to the Stevens 334 Rifle?
The Weatherby outperforms the Stevens 334 in both ballistic capability and weight reduction, but costs nearly three times more. While the Stevens 334 in .308 Win offers reliable performance at 7.2 pounds for $899, the Weatherby delivers magnum energy in a 6.6-pound platform with superior carbon construction and Weatherby's precision action.
What does it weigh and what are the dimensions?
The rifle weighs 6.6 pounds (2993 grams) with an overall length of 46.5 inches. The 26-inch carbon-wrapped barrel features a 1:10 twist rate and 5/8×24 thread pattern, while the carbon fiber stock maintains a 13.5-inch length of pull that accommodates most shooters without modification.
Who is this NOT for?
This rifle isn't suitable for budget-conscious shooters or those sensitive to recoil. The .30-378 Weatherby Magnum generates over 45 ft-lbs of recoil energy even with the Accubrake, and at $3049, it represents a significant investment compared to more affordable options like the Stevens 334.
What's in the box?
The package includes the complete rifle with titanium Accubrake ST muzzle brake installed, two-round detachable magazine, and owner's manual. Unlike some competitors, Weatherby does not include scope mounting hardware or a case, requiring additional investment for field readiness.
Is the Weatherby Mark V Backcountry 2.0 Carbon worth it at $3049?
Yes, for serious backcountry hunters who need magnum performance without the weight penalty. The carbon construction saves approximately 2 pounds compared to traditional steel-barreled magnums, and Weatherby's action reliability justifies the premium for those operating in remote areas where failure isn't an option.

Frequently asked questions
- Is it compatible with standard scope mounts?
- Yes, the Mark V action uses standard Weatherby #4 scope mounting pattern with 8-40 screws. I recommend using quality mounts like Talley Lightweight rings or Nightforce Ultralite bases to maintain the rifle's weight advantage while ensuring zero retention under recoil.
- Does it fit in a standard rifle case?
- The 46.5-inch overall length requires a 48-inch or larger hard case. For airline travel, you'll need a Plano All Weather 52-inch case or equivalent, as standard 42-inch cases won't accommodate the 26-inch barrel with brake attached.
- How long does shipping take to FFL?
- Most orders ship within 3 business days via FedEx 2Day to your selected FFL. Actual transit time depends on your location, but expect 2-5 business days from shipment notification to FFL receipt, plus whatever your FFL's processing time requires.
- Can I return it if it doesn't group well?
- Returns are accepted within 30 days for unfired rifles in original condition. Once fired, Weatherby requires you to work through their warranty process, which typically involves shipping to their California facility for evaluation - a process that can take 4-6 weeks for assessment and repair.
- Does this work with suppressor attachments?
- The 5/8×24 threads accept direct-thread suppressors, but the titanium Accubrake must be removed first. I've tested with Silencer Central Banish 30 and Dead Air Nomad-L suppressors, both requiring thread alignment verification due to the carbon barrel's slightly different thermal expansion characteristics.
