The Weatherby Mark V Backcountry 2.0 .300 Wby Mag is a purpose-built lightweight rifle that doesn’t compromise on terminal performance or precision. At 5.9 pounds, it pairs the legendary Mark V action with a Peak 44 Blacktooth carbon stock, a TriggerTech trigger, and Weatherby’s Accubrake ST muzzle brake. This is a rig designed for the shooter who needs to carry far and shoot flat — and it delivers on both counts.

Key Features
- Peak 44 Blacktooth Carbon Stock — Why it matters: This isn’t just light; it’s a torsionally rigid platform that keeps harmonics consistent shot after shot, even with a hot .300 Wby Mag load.
- TriggerTech Trigger — Why it matters: Adjustable from 2.5 to 5 pounds with zero creep, this trigger gives you a crisp break that helps you call your shots at distance.
- Fluted and Threaded Barrel with Accubrake ST — Why it matters: The fluting sheds weight and aids cooling, while the Accubrake ST cuts recoil by up to 53% — a real advantage when you’re spotting your own impacts.
- Three-Lug Mark V Action with 54° Bolt Lift — Why it matters: That short throw keeps your eye in the scope during fast follow-ups, and the nine locking lugs provide rock-solid lockup for accuracy.
Who It’s For
This rifle is for the backcountry hunter who hikes miles with a heavy pack and expects first-round hits on elk or sheep at 400+ yards. It’s also for the long-range shooter who wants a magnum platform that doesn’t beat you up — the Accubrake ST and carbon stock tame the .300 Wby Mag recoil to something closer to a .308.
Pros & Cons
Pros: Sub-6-pound weight with magnum power, TriggerTech trigger is competition-grade, Accubrake ST makes it shootable, carbon stock is rock-solid and weatherproof.
Cons: The 3+1 magazine capacity is tight for a field rifle — if you’re used to detachable box mags, this might feel limiting. Also, the .300 Wby Mag ammo isn’t as widely stocked as .300 Win Mag, so plan your supply chain.

FAQ
Are Weatherby Mark V rifles accurate?
Yes. The Mark V action has been a benchmark for accuracy since 1957. The Backcountry 2.0, with its free-floated barrel, TriggerTech trigger, and rigid carbon stock, consistently produces sub-MOA groups with quality ammunition. Many shooters report 0.5–0.75 MOA with handloads.
Are Weatherby Mark V rifles worth the money?
For a precision-oriented shooter who values both light weight and magnum performance, yes. The combination of a hand-laid carbon stock, a premium trigger, and a factory-installed brake at $2,499 is competitive with custom builds that cost significantly more. You’re paying for a proven action and a rifle that’s ready to hunt out of the box.
What is the maximum effective range of the .300 Wby Mag in this rifle?
With a 26-inch barrel and 180-grain loads, you’re looking at 3,100+ fps muzzle velocity. Ethical kill range on game is 500+ yards with proper shot placement; for steel, you can stretch it to 1,200 yards with the right optic.
Can I mount a suppressor on the Backcountry 2.0?
Yes. The barrel is threaded 5/8×24, so you can direct-thread a suppressor or use a muzzle device adapter. Just note that the Accubrake ST is pinned and welded from the factory — you’ll need to have a gunsmith remove it if you want a dedicated suppressor mount.
