Description
There's a reason the Backcountry line has become the go-to for serious mountain hunters, and this Mark V BC Carbon in .240 Weatherby Magnum shows off everything Weatherby learned building it. The 22 inch BSF carbon fiber barrel wraps a match-grade stainless core in tensioned carbon fiber, shaving weight up front while adding rigidity and helping the barrel shed heat between shots. Out at the muzzle you get 5/8×24 threading with Weatherby's Accubrake ST, so the rifle stays flat and pleasant to shoot, and swapping to a suppressor down the road is a simple job.
Why the BC Carbon Earns Its Spot in the Truck
The stock is where this rifle really separates itself. Weatherby went with a Peak 44 carbon fiber stock, one of the lightest production stocks out there, finished in a green and brown sponge pattern over exposed carbon. The 3DHEX recoil pad uses a printed lattice structure to soak up recoil and tame muzzle lift, which honestly matters less with the mild-mannered .240 Wby but makes shooting off a pack downright comfortable. Metalwork wears Patriot Brown Cerakote for real weather resistance, the receiver comes drilled and tapped for optics, and the crisp TriggerTech trigger breaks clean with zero creep. Capacity is 5+1 through a traditional hinged floorplate.
The .240 Weatherby Magnum Advantage
The .240 Wby Mag is one of the most underrated deer and antelope cartridges going. It pushes 6mm bullets faster than a .243 Win with a trajectory that makes those long cross-canyon pokes feel a lot shorter, all with recoil light enough to watch your own hits. Paired with the 1-in-10 twist barrel, it handles classic 85 to 100 grain hunting bullets beautifully.
Backed by Weatherby's Sub-MOA Promise
Like every Mark V, this rifle carries Weatherby's sub-MOA accuracy guarantee with premium or Weatherby factory ammo. Between the carbon barrel, quality stock, and that 54 degree bolt throw the Mark V action is famous for, this is a rifle you buy once and hunt with for decades.

Frequently Asked Questions
Does the Weatherby Mark V BC Carbon come with a muzzle brake, and can I run a suppressor instead?
Yes, it ships with Weatherby's Accubrake ST installed on the 22 inch barrel. The muzzle is threaded 5/8×24, which is the standard pattern for most 30 caliber and smaller suppressors and muzzle devices, so swapping to a can or thread protector is quick and easy.
Is the Mark V BC Carbon covered by Weatherby's accuracy guarantee?
It is. Weatherby guarantees Mark V rifles will print a 3-shot group of .99 inch or better at 100 yards from a cold barrel using Weatherby factory or premium ammunition. Between the tensioned BSF carbon fiber barrel and the TriggerTech trigger, this one has all the ingredients to beat that number handily.
What is the .240 Weatherby Magnum good for?
Think of it as a hot-rodded 6mm that outruns the .243 Winchester. It shines on deer, antelope, and hogs at extended ranges, and it doubles as a fantastic coyote rifle. Recoil is mild, especially with the Accubrake and 3DHEX pad, so it's easy to shoot well and spot your own impacts.
How do I mount a scope on this rifle?
The receiver comes drilled and tapped from the factory with no iron sights, so it's ready for a scope right out of the box. You'll want bases or a rail made for the Weatherby Mark V action, which are widely available from Talley, Leupold, Warne, and others.
