Description
Hauling a .300 Weatherby Magnum ten miles into elk country used to mean earning every ounce. The Mark V Backcountry 2.0 changes that math. At 6.2 pounds bare, this rifle carries like a lightweight sporter but hits with the flat-shooting authority that made Roy Weatherby's flagship cartridge famous. The weight savings come from everywhere: a fluted 26 inch barrel, deep spiral fluting on the bolt body, a skeletonized aluminum bolt knob, and the Peak 44 Blacktooth carbon fiber stock, which weighs a scant 19 ounces and ranks among the lightest production stocks you can buy.
The Mark V Action, Trimmed Down and Dressed Up
Underneath all the modern materials sits the same nine-lug Mark V action that has anchored Weatherby's magnum rifles for decades. The three-row lug arrangement handles high-pressure cartridges with plenty of margin, and the short 54 degree bolt lift means faster cycling and more clearance under low-mounted glass. The spiral fluting on the bolt does more than shed weight; less bearing surface inside the receiver makes for a noticeably slicker throw. A TriggerTech trigger breaks clean with zero creep and minimal overtravel, and it adjusts externally if you want to fine-tune the pull. Weatherby backs the whole package with their sub-MOA guarantee when fed factory or premium ammunition.
Backcountry 2.0 Recoil Management That Works
A light rifle in .300 Wby Mag could be punishing, but this one is set up to take the sting out. The Accubrake ST uses 30 symmetrically spaced ports to bleed off recoil energy, and the 3DHEX printed recoil pad features internal collapsing voids that stretch the recoil impulse over time instead of delivering it all at once. The combination makes range sessions and follow-up shots far more manageable than the chambering suggests.
The Patriot Brown Cerakote on the barrel, receiver, and trigger guard shrugs off weather, while the dark green and brown sponge pattern on the stock looks right at home on a mountain. The receiver comes drilled and tapped, so mount your favorite scope, zero it, and go hunt.

Frequently Asked Questions
How much does the Mark V Backcountry 2.0 in .300 Wby Mag actually weigh?
This magnum-chambered version runs about 6.2 pounds bare. Add a lightweight scope and rings and you are still looking at a rig in the low 7 pound range, which is remarkable for a full-power .300 Weatherby Magnum with a 26 inch barrel. That makes it a genuine all-day carry rifle for mountain hunts.
Is the recoil manageable in a rifle this light?
More than you would expect. The Accubrake ST has 30 ports that vent gas to cut recoil substantially, and the 3DHEX recoil pad uses collapsing internal voids to spread the impulse out rather than deliver a sharp jab. Most folks find it kicks closer to a standard .30-06 rifle than a lightweight magnum. Just plan on ear protection at the range since brakes do increase muzzle blast.
Does the Backcountry 2.0 come with sights or a scope?
No, it ships without sights or optics. The receiver comes drilled and tapped for scope bases, so you will want to budget for quality rings and glass. Given the flat trajectory of the .300 Wby Mag, a solid variable-power hunting scope is the natural pairing.
Is this rifle guaranteed to shoot sub-MOA?
Yes. Weatherby guarantees all Mark V rifles will print a three-shot group of .99 inch or less at 100 yards from a cold barrel using Weatherby factory or premium ammunition. The guarantee applies to the original purchaser for two years from a verified purchase date, so register it after you buy.
