About this product
The Weatherby Mark V Backcountry 2.0 Carbon .300 WBY Mag 26" is a lightweight magnum rifle designed for backcountry hunters who need Weatherby Magnum performance without the typical weight penalty. This rifle combines Weatherby's proven Mark V action with advanced carbon fiber construction to deliver a 6.6 lb platform capable of handling the powerful .300 Weatherby Magnum cartridge. The Peak 44 Blacktooth carbon stock and 3DHEX recoil pad work together to manage recoil during extended field use.
What is the Weatherby Mark V Backcountry 2.0 Carbon used for?
This rifle is specifically designed for backcountry big game hunting where weight matters but magnum performance is non-negotiable. The .300 Weatherby Magnum chambering delivers over 4,000 foot-pounds of muzzle energy, making it suitable for elk, moose, and bear at extended ranges. The 26-inch carbon-wrapped barrel maintains velocity for ethical shots beyond 400 yards while keeping the entire package under 6.6 pounds.
How does the Weatherby Mark V Backcountry 2.0 Carbon compare to the Stevens 334 Rifle?
The Weatherby outperforms the Stevens 334 in long-range ballistics but requires more shooter skill. While the Stevens 334 in .308 Win delivers approximately 2,600 ft-lbs from its 20-inch barrel, the Weatherby generates over 4,000 ft-lbs from its 26-inch carbon barrel. The Weatherby is better for experienced hunters needing 600+ yard capability, while the Stevens suits budget-conscious shooters staying under 300 yards.
What does it weigh and what are the dimensions?
The rifle weighs exactly 6.60 pounds and measures 48.50 inches overall with its 26-inch barrel. The carbon fiber barrel construction reduces weight by approximately 1.8 pounds compared to a traditional steel barrel of the same length. The receiver measures 1.375 inches in diameter, matching standard Mark V dimensions for scope mounting compatibility.
Who is this NOT for?
This rifle is not for beginner shooters or those sensitive to recoil—the .300 Weatherby Magnum generates over 35 ft-lbs of recoil energy even with the Accubrake ST. It's also ill-suited for tight quarters hunting where the 48.5-inch overall length becomes cumbersome. Budget-conscious hunters might prefer the more affordable Stevens 334 in .243 Win for similar weight with less power.
What's in the box?
The rifle ships with one 3-round detachable box magazine, owner's manual, and warranty card. Ironclad Armory includes a complimentary thread protector for when you remove the factory-installed Accubrake ST muzzle brake. The packaging consists of a plastic hard case with foam inserts, weighing approximately 12 pounds total with the rifle secured inside.
Is the Weatherby Mark V Backcountry 2.0 Carbon worth it at $3,049?
At $3,049, this rifle justifies its price for serious backcountry hunters who value every ounce. The carbon fiber construction saves approximately 28% weight compared to traditional magnum rifles while maintaining accuracy standards. For hunters covering 10+ miles daily in mountain terrain, the weight savings translate directly to increased mobility and endurance.

Frequently asked questions
- Is it compatible with standard Weatherby Mark V accessories?
- Yes, it accepts all standard Mark V scope bases and magazines. The receiver uses the standard Mark V mounting pattern, accepting Talley, Leupold, and Weatherby-branded bases. The magazine well accommodates any Weatherby Mark V .300 WBY Mag magazine with 3-round capacity.
- Does it fit in a standard rifle case?
- You'll need a 50-inch case minimum due to the 48.5-inch overall length. Most standard 48-inch cases won't close properly. I recommend Plano All-Weather 52-inch cases, which provide adequate clearance and protection for the carbon fiber components during transport.
- How long does shipping take to Montana?
- Ironclad Armory processes firearms shipments within 3 business days, with ground shipping taking 5-7 additional days to Montana. All firearms ship to your local FFL dealer, who will conduct the required background check before transfer. Expedited shipping is available for an additional $75.
- Can I return it if it doesn't fit my needs?
- Ironclad Armory accepts returns within 30 days if the firearm is unfired and in original condition. The return process takes 7-10 business days once the firearm reaches our facility. Custom orders and fired firearms are not eligible for return under any circumstances.
- Does this work with suppressor attachments?
- The 26-inch barrel has 5/8x24 threads under the factory Accubrake ST. It's suppressor-ready for .30 cal models like the SilencerCo Omega 300. You'll need to remove the muzzle brake first—the thread protector measures 0.9 inches long and weighs 1.2 ounces.
