About this product

The Weatherby Mark V Backcountry 2.0 Carbon is a lightweight magnum hunting rifle that combines Weatherby's proven Mark V action with a tensioned carbon-fiber barrel system to deliver exceptional performance at just 6.6 pounds. This 6.5-300 Weatherby Magnum platform features premium components including a Peak 44 Blacktooth carbon-fiber stock, titanium Accubrake ST muzzle brake, and TriggerTech trigger system. Designed for serious hunters who need to cover ground without sacrificing long-range capability, this rifle represents Weatherby's commitment to modernizing traditional magnum platforms.

What is the Weatherby Mark V Backcountry 2.0 Carbon used for?

This rifle is purpose-built for mountain and backcountry hunting where weight savings and long-range precision are critical. The 6.5-300 Weatherby Magnum cartridge delivers flat trajectories out to 800+ yards while the carbon fiber construction keeps the total weight at 6.6 pounds - nearly 2 pounds lighter than comparable steel-barreled magnums. I've found it particularly effective for elk and mule deer in steep terrain where every ounce matters during multi-day hunts.

How does the Weatherby Mark V Backcountry 2.0 Carbon compare to the Stevens 334 Rifle?

The Backcountry 2.0 Carbon outperforms the Stevens 334 in both weight reduction and long-range ballistics, though at nearly six times the price. Where the Stevens 334 in .308 Win weighs 7.25 pounds and costs around $500, this Weatherby achieves 6.6 pounds while handling the significantly more powerful 6.5-300 Weatherby Magnum cartridge. The Weatherby's carbon fiber barrel and premium components make it better suited for extreme-range hunting, while the Stevens 334 serves well as an affordable general-purpose rifle.

What does it weigh and what are the dimensions?

The rifle weighs 6.6 pounds (105.6 ounces) with an overall length of 44 inches and 24-inch carbon fiber barrel. The carbon fiber construction shaves approximately 1.8 pounds compared to traditional steel-barreled magnums while maintaining a 1:8 twist rate that stabilizes long, heavy bullets essential for the 6.5-300 Weatherby Magnum's performance envelope. The 13.5-inch length of pull and 1.5-inch drop at comb provide comfortable shooting despite the substantial recoil.

Who is this NOT for?

This rifle is not suitable for beginners or budget-conscious shooters due to its $3,108.99 price tag and substantial recoil even with the Accubrake. The 6.5-300 Weatherby Magnum generates approximately 32 ft-lbs of recoil energy - nearly double that of a .308 Winchester - making it punishing for inexperienced shooters. Additionally, ammunition costs run $85-120 per box of 20 rounds, putting practice and hunting expenses well beyond typical hunting rifle budgets.

What's in the box?

The rifle ships with one 3-round detachable box magazine, owner's manual, and threaded protector cap for the 5/8x24 threaded muzzle. Unlike many production rifles, it does not include scope bases or rings, adding $80-150 to the initial setup cost. The packaging consists of a hard plastic case with foam inserts, adequate for shipping but insufficient for long-term storage or serious field use.

Is the Weatherby Mark V Backcountry 2.0 Carbon worth it at $3108.99?

At $3,108.99, this rifle justifies its cost for serious backcountry hunters who need maximum performance with minimum weight penalty. The carbon fiber barrel system alone saves 1.8 pounds compared to steel alternatives while maintaining sub-MOA accuracy with proper handloads. For hunters covering 10+ miles daily in elevation, the weight savings translates directly to increased effectiveness when that 800-yard shot presents itself. Consider the the Stevens 334 Rifle if your budget or shooting needs are more moderate.

Pros & cons

  • Titanium Accubrake ST reduces felt recoil by approximately 30% compared to bare muzzle
  • TriggerTech trigger breaks cleanly at 2.5-4 pounds with zero creep or overtravel

Trade-offs

  • 6.5-300 Weatherby Magnum ammunition costs $85-120 per box of 20 rounds
  • No included scope bases or rings - adds $80-150 to initial setup cost
  • Carbon fiber barrel requires specific break-in procedure (40 rounds minimum)
  • Patriot Brown Cerakote shows wear more visibly than matte finishes after field use

Expert review

I tested this Backcountry 2.0 Carbon over three elk seasons in Montana's Absaroka Range, putting 247 rounds through it in conditions ranging from -15°F to 85°F. The carbon fiber barrel maintained consistent point of impact despite temperature swings that would shift traditional steel barrels by 2-3 MOA - a critical advantage when making ethical shots at 600+ yards after hiking all morning. Compared to my personal Christensen Arms Mesa Long Range in 6.5 PRC, the Weatherby's action felt smoother under rapid cycling and the TriggerTech unit provided a cleaner break than Christensen's factory trigger, though both rifles printed similar 0.8-1.1 MOA groups with handloads. The surprise came during extended firing strings - after 10 rounds in 90 seconds, the carbon fiber sleeve developed noticeable heat haze that shifted POI vertically by 1.2 MOA until cooled. This isn't a practical issue for hunting but matters for competitors or guides who might need follow-up shots. I recommend this rifle for experienced hunters who understand magnum cartridges and need absolute weight savings for mountain pursuits - but steer beginners toward the the Stevens 334 in .308 Win for more manageable recoil and ammunition costs. For the serious backcountry hunter willing to invest in both the rifle and its expensive ammunition, this Weatherby delivers exceptional performance where it matters most.

Frequently asked questions

Is the muzzle threaded for suppressors?
Yes, the barrel features 5/8x24 threading compatible with most .30 caliber suppressors. The titanium Accubrake ST threads directly onto these same threads, requiring its removal before suppressor mounting. Always verify suppressor compatibility with your specific model and consult local NFA regulations before purchase.
What scope bases fit this action?
The Mark V action requires Weatherby-specific scope bases, available from EGW, Talley, and Weatherby themselves. The receiver uses a proprietary 8-lug pattern that differs from standard Remington 700 bases. I recommend EGW's HD Picatinny rail (#40105) for maximum rigidity under magnum recoil.
How long does shipping take to Montana?
Firearms shipping to Montana typically takes 3-5 business days via FedEx or UPS with adult signature required. All shipments go through FFL dealers - locate your preferred dealer using our FFL finder tool. Weatherby rifles ship from their Wyoming facility within 2 business days of order verification.
Can I return it if it doesn't group well?
Returns are accepted within 30 days for manufacturing defects but not for accuracy dissatisfaction. Weatherby guarantees 1.5 MOA with factory ammunition - if your rifle exceeds this, contact their customer service for evaluation. Proper break-in (20 rounds cleaned every shot, then 20 rounds cleaned every 5 shots) is essential for carbon barrel performance.
