Pros & cons
What works

About this product
The Weatherby Mark V Backcountry 2.0 Carbon .300 Weatherby Mag LH is a left-hand bolt-action hunting rifle built to deliver magnum performance in a lightweight, mountain-ready package. It combines a tensioned carbon fiber barrel, Peak 44 Blacktooth carbon fiber stock, and the Mark V action finished in Patriot Brown Cerakote, aiming to reduce weight without sacrificing the action's legendary nine-lug reliability. This is for the experienced hunter who demands left-handed ergonomics and the flat-shooting ballistics of a .300 Weatherby Magnum, and it's shipped ready for optics with a drilled and tapped receiver.
What is the Weatherby Mark V Backcountry 2.0 Carbon used for?
This rifle is engineered for high-altitude, long-range hunting of elk and moose where every ounce in the pack matters. The 6.7-pound platform, coupled with the hard-hitting .300 Weatherby Magnum cartridge, provides extended effective range and terminal authority on large game. Its titanium Accubrake ST and 3DHEX recoil pad significantly improve shooter comfort over multiple shots compared to an uncompensated magnum rifle, making follow-up shots more practical.
How does the Backcountry 2.0 Carbon compare to the Stevens 334?
The Backcountry 2.0 Carbon is objectively superior for backcountry hunting of heavy game where weight and ballistics are critical, while the Stevens 334 in .308 Win is a better choice for budget-conscious deer hunting at moderate ranges. My assessment is that the Weatherby offers a 3.2-pound weight advantage, a far more powerful cartridge, and a premium action, but at nearly five times the cost of the Stevens rifle. The Stevens 334 is a reliable tool for 300-yard work; the Weatherby is built for 600-yard-plus shots in demanding terrain.
What does it weigh and what are the dimensions?
The Backcountry 2.0 Carbon weighs 6.7 pounds, has an overall length of 48.5 inches, and features a barrel with a 1-in-10 twist rate. The magazine holds three rounds, plus one in the chamber, and the receiver is prepped with 8-40 scope mount holes. Its 5/8x24 threaded muzzle accommodates the included Accubrake ST or most .30 caliber muzzle devices and suppressors rated for the cartridge's pressure.
Who is this NOT for?
This rifle is not for a first-time shooter, a hunter on a tight budget, or anyone who primarily targets whitetail deer inside 200 yards. The .300 Weatherby Magnum generates substantial recoil and muzzle blast, even with the brake, and the ammunition is expensive, often costing over $100 for a box of 20. For those applications, a standard .30-06 or a rifle like the Stevens 334 in .243 Win is a more sensible, affordable, and pleasant-to-shoot option.
What's in the box?
The rifle ships with the titanium Accubrake ST muzzle brake pre-installed on the 5/8x24 threads and a single three-round steel magazine. No iron sights, scope mounts, or sling are included, as the platform is designed from the ground up for a precision optic system. The initial setup requires mounting a scope, which typically adds 1-2 pounds and several hundred to several thousand dollars to the complete system weight and cost.
Is the Weatherby Mark V Backcountry 2.0 Carbon worth it at $3,299?
Yes, if you are a left-handed hunter specifically pursuing elk, moose, or bear in steep, remote country and your success hinges on a rifle that saves 2-3 pounds over a traditional steel-barreled magnum. The cost buys you a purpose-built, sub-7-pound magnum rifle with proven recoil mitigation and Weatherby's nine-lug action. If you hunt from a stand or truck, or if you do not need left-handed controls, that $3,299 is better spent on optics, ammunition, and a more affordable right-hand rifle.

Frequently asked questions
- Is it compatible with a suppressor?
- Yes, the 5/8x24 threaded muzzle is a standard for .30 caliber suppressors. However, you must verify the suppressor's pressure rating with the manufacturer, as the .300 Weatherby Magnum operates at peak pressures of approximately 65,000 PSI, which exceeds some standard .30-cal can limits.
- What scope mount pattern does it use?
- It uses a standard Remington 700 Long Action footprint, the most common pattern for aftermarket rails and rings from companies like Talley, Nightforce, and Seekins Precision. The receiver is drilled and tapped with 8-40 screw holes, which are standard for high-magnification optics.
- How long does shipping take to Montana?
- All firearm shipments from Ironclad Armory are processed within 1-2 business days and shipped via FedEx 2Day to your selected FFL dealer. Total transit time from order to dealer notification is typically 4-7 business days, dependent on FFL paperwork verification.
- Does it work with a standard bipod?
- No, the carbon fiber stock does not have a sling stud or swivel stud at the forend to directly attach a Harris or similar bipod. You will need an aftermarket accessory rail, such as an M-LOK or Picatinny section, which can be mounted to the stock's forend using an adapter kit from companies like Magpul.
