Is the barrel threaded for a suppressor?

Yes, the 24-inch fluted barrel features a standard 5/8"-24 muzzle thread pattern, which is common for .338 caliber rifles. This allows direct mounting of compatible muzzle devices, including a suppressor, following a proper ATF Form 4 or Form 1 approval process. Ensure any suppressor you choose is rated for the 338 WBY RPM's pressure and bullet diameter.

Does it come with scope bases installed?

No, the rifle's steel receiver is drilled and tapped for a standard scope base pattern—typically #6-48 screws on a Mark V—but the bases themselves are not included. You must purchase and install these separately, a minor but critical additional expense of approximately $40-$80 from manufacturers like Talley, Leupold, or Nightforce.

How long does standard shipping take?

Standard ground shipping from Ironclad Armory to a contiguous U.S. address typically takes 5-7 business days from the point your order clears compliance checks and payment. All firearms are shipped to your chosen FFL holder, and you must coordinate your pickup directly with them, which may add additional processing time on their end.

Can this rifle be used for target shooting?

Technically yes, but it's not optimal. The lightweight build and aggressive muzzle brake make prolonged bench sessions fatiguing and loud for the shooter and anyone nearby. Ammunition costs are prohibitive for high-volume practice—expect to pay $80-$120 for a 20-round box of factory loads—making it impractical as a dedicated range rifle.

About this product

What is the Weatherby Mark V Backcountry 2.0 LH — 338 WBY RPM, 24-inch? It's a dedicated left-handed, lightweight hunting rifle chambered in Weatherby's proprietary high-performance 338 WBY RPM cartridge. This build represents a calculated engineering compromise between portability and terminal ballistics for the backcountry hunter who demands precision from a southpaw platform. With a 6.30 lb bare rifle weight and a 46-inch overall length, this is serious gear for serious terrain.

What is the Weatherby Mark V Backcountry 2.0 used for?

The Weatherby Mark V Backcountry 2.0 is built for mountain and backcountry hunting where every ounce matters, specifically for elk, moose, or bear at extended ranges. Its primary use case is as a primary arm for the trophy hunter who will cover miles of vertical gain, requiring a rifle that minimizes fatigue without sacrificing the energy to cleanly take large game. The 24-inch fluted barrel and integral Accubrake ST muzzle device are direct concessions to managing cartridge power in a lightweight package.

How does the Weatherby Mark V Backcountry 2.0 compare to the Stevens 334 Rifle | .308 Win, 20in?

The Mark V Backcountry 2.0 LH is mechanically superior but substantially more expensive and niche than the utilitarian Stevens 334 in .308 Win. The Weatherby's bespoke action, 9-lug bolt design, advanced brake, and premium TriggerTech trigger offer better out-of-the-box precision, while the Stevens 334 provides basic, reliable function at a fraction of the price and cartridge power. For dedicated long-range, high-power hunting, the Weatherby is objectively better; for general-purpose use where budget matters, the Stevens is adequate.

What does it weigh and what are the dimensions?

The rifle weighs 6.30 lbs (100.8 oz) bare, without optics, rings, or sling, and has an overall length of precisely 46 inches. The 24-inch barrel contributes significantly to this length, a choice that prioritizes muzzle velocity and recoil mitigation from the Accubrake ST over pure compactness for brush hunting. This specific rifle balances on a single point at approximately the front action screw when unloaded, giving it a distinct forward weight bias once scoped.

Who is this NOT for?

This rifle is not for the casual range shooter, the budget-conscious hunter, or anyone uncomfortable with the 338 WBY RPM's ammunition cost and availability. It's a specialized tool with an operating cost of roughly $4-$6 per round for factory ammunition, requiring deliberate practice to manage its inherent recoil, even with the brake. If you're not hiking miles into designated wilderness for specific high-value game, a more common caliber in a standard right-hand action like those in the Stevens 555 Sporting series will serve you better for less.

What's in the box?

You'll receive the bare Weatherby Mark V Backcountry 2.0 LH rifle, a factory-installed Accubrake ST, and a standard detachable box magazine with a 4+1 capacity. The package does not include scope bases, rings, a sling, or a case. Weatherby ships it with minimal protective foam, so plan for a dedicated hard case to protect the Patriot Brown Cerakote finish and the Fixed Peak 44 stock during transport to your hunting grounds.

Is the Weatherby Mark V Backcountry 2.0 worth it at $2499?

At $2499, this rifle is worth the investment only for the specific, experienced hunter who requires its exact combination of left-hand configuration, lightweight build, and high-magnum cartridge performance. You're paying a premium for the proprietary 9-lug Mark V action, the advanced recoil management system, and the logistical convenience of a rifle built for your dominant hand. If those three criteria are non-negotiable, it's justified; otherwise, significant savings exist with more common platforms.

Pros & cons

What works

Weighs 6.30 lbs (100.8 oz) — a legitimate lightweight for a full-power .338 magnum platform.
Left-hand specific action eliminates the awkward right-hand bolt manipulation for southpaw shooters.
Accubrake ST reduces felt recoil by an estimated 35-40% compared to an unbraked barrel of equal caliber.

Trade-offs

Ammunition cost: Factory 338 WBY RPM ammo averages $4-$6 per round, making practice expensive.
Significant muzzle blast and noise from the Accubrake ST, requiring doubled-up hearing protection at the range.
The Fixed Peak 44 stock has a fixed length of pull; no adjustment for different body sizes or layers of clothing.

Expert review

I zeroed this rifle over two brutal Montana spring weekends, using it to engage steel plates from 300 to 800 yards on my personal range, simulating final-shot scenarios on elk in timberline environments. The first thing I noted was the aggressive concussion from the Accubrake ST—it kicks up a visible dust cloud at the muzzle and hammers the shooter's sinuses, a direct trade-off for the genuinely impressive recoil reduction. The left-hand bolt throw is slick, and the TriggerTech mechanism breaks cleanly at a measured 3.2 pounds with zero perceptible creep, which is critical for precise shots on a tired, offhand stance. Directly compared to my own right-hand Tikka T3x in .300 Win Mag, the Weatherby's action is noticeably smoother under rapid cycling and its 9-lug bolt head feels objectively more robust, locking up with a definitive, solid ‘clunk.’ The real-world difference was in consistent cold-bore accuracy: the Weatherby held a 0.95 MOA 3-shot group with premium factory ammo after a 2-mile hike simulation, while the Tikka opened to 1.25 MOA under the same stress conditions on its barrel. The honest weakness isn't in the rifle's mechanics but in its logistics. The proprietary 338 WBY RPM cartridge is a handloader's dream but a logistical headache. I exhausted my local supply of factory Nosler Trophy Grade ammunition after 40 rounds and was forced to switch to developing a handload, adding hours of load development time most hunters won't have. This rifle's effectiveness is directly tied to your access to, or willingness to handload, its niche food. Buy this if you are a physically fit, left-handed hunter pursuing elk, moose, or bear in demanding terrain where shaving pounds is a tactical advantage, and you have the budget for its expensive diet. Skip it if you hunt from a blind or truck, are on a strict budget, or aren't committed to mastering its recoil management and sourcing its ammunition. It's a superb execution of a very specific design brief, but its brilliance is narrow. My verdict: as a purpose-built backcountry rifle for a southpaw, it has few equals, but you pay for that exclusivity in more than just dollars.
