Description
There's a reason the Backcountry 2.0 Carbon keeps showing up on the packs of serious mountain hunters. Weatherby took the classic steel Mark V action, wrapped a BSF tensioned carbon fiber barrel around it, and dropped the whole thing into a Peak 44 Blacktooth stock, one of the lightest production carbon fiber stocks you can buy. The result is a rifle right around 5.9 pounds that still carries Weatherby's sub-MOA guarantee, a 3-shot group of .99 inches or better at 100 yards with factory or premium ammo. That barrel system has real credentials too. In 2021, a Mark V wearing this same BSF barrel set Weatherby's internal accuracy record with a 0.06 inch three-shot group.
Why the Backcountry 2.0 Carbon Carries So Well
The 6.5 Weatherby RPM chambering was practically made for this platform. Built on the slim six-lug Mark V action, it pushes 140 grain bullets north of 3,000 fps without the punishing recoil of the bigger Weatherby magnums, and the 24 inch #4 contour carbon barrel with a 1:8 twist stabilizes the long, high-BC bullets you want for cross-canyon shots. Recoil gets tamed twice over: a titanium Accubrake ST with 30 symmetrical ports up front, and Weatherby's 3DHEX recoil pad out back, a 3D printed lattice that collapses progressively to stretch out the recoil impulse. In a rifle this light, that combination matters.
Details That Set This Mark V Apart
The spiral fluted bolt trims weight and reduces bearing surface for a smoother throw, and the skeletonized aluminum bolt knob is easy to run with gloves on. The externally adjustable TriggerTech trigger breaks with zero creep, and all the exposed metal wears Patriot Brown Cerakote, with the stock finished in a dark green and brown sponge pattern over raw carbon fiber. Feeding comes from a 4+1 internal magazine with a hinged floorplate, so there's no detachable mag to lose ten miles from the truck. Pair it with a lightweight scope and you've got a complete setup that won't wear you down on the climb but will absolutely deliver when a shot presents itself.

Frequently Asked Questions
What is the 6.5 Weatherby RPM and how does it compare to 6.5 Creedmoor?
The 6.5 Weatherby RPM (Rebated Precision Magnum) was designed specifically for the slim six-lug Mark V action. It pushes 140 grain bullets around 3,000 fps or better, giving you a noticeable velocity edge over the 6.5 Creedmoor with flatter trajectory and more energy downrange. Recoil stays manageable, especially with the Accubrake and 3DHEX pad on this rifle.
Is the Backcountry 2.0 Carbon accurate enough for long-range hunting?
Yes. Every Mark V rifle comes with Weatherby's sub-MOA guarantee, a three-shot group of .99 inches or less at 100 yards from a cold barrel with Weatherby factory or premium ammo. Owners regularly report half-MOA groups from this platform, and the BSF barrel system set Weatherby's internal accuracy record with a 0.06 inch group.
Does the Weatherby Backcountry 2.0 Carbon come with a scope or sights?
No, this rifle ships without sights or optics. The receiver is drilled and tapped, so you just need bases or a rail and rings for your scope of choice. Given the rifle's featherweight build, most hunters pair it with a lightweight 3-15x or similar hunting scope to keep the whole package under seven and a half pounds.
Can I run a suppressor on the Backcountry 2.0 Carbon?
You can. The muzzle is threaded 5/8-24, which is the standard pattern for most 6.5mm and .30 caliber suppressors and muzzle devices. Just remove the factory titanium Accubrake ST and thread on your can. Keep in mind a suppressor adds length and weight up front, so the shorter overall balance may shift a bit.
