Description
There has always been a tradeoff with mountain rifles: cut the weight and you pay for it at the shoulder, especially in a magnum chambering. The Mark V Backcountry Guide takes a real swing at that problem. Weatherby paired a 22 inch BSF carbon fiber barrel with a machined titanium Accubrake ST, which they rate at up to 53 percent felt recoil reduction, then added Peak 44's 3DHex recoil pad with its energy absorbing honeycomb structure. The result is a .300 Win Mag you can carry all day into steep country and still shoot comfortably enough to practice with.
What Sets the Backcountry Guide Apart
The Peak 44 Blacktooth stock is a big part of the story here. It is built around a carbon fiber bedding block that engages the front recoil lug and pushes recoil energy out to the shell of the stock, and each one gets hand painted sponge pattern accents so no two rifles look quite the same. Weatherby also installed two Spartan Precision gunsmithing adapters in the forend, so if you run Spartan's ultralight bipods and tripod accessories, you can clip in without adding rails or hardware. Underneath it all is the proven Mark V action with a nine lug bolt, deep spiral fluting, a fast 54 degree bolt throw that clears low mounted scopes, and a removable bolt knob if you want to swap in your own.
Shooting the Mark V Backcountry Guide .300 Win Mag
The externally adjustable TriggerTech trigger breaks with zero creep and lets you dial the pull weight to your liking, and BSF's tensioned carbon barrel construction keeps the rifling straight as the barrel heats up. Weatherby stands behind the accuracy too, guaranteeing sub-MOA three shot groups at 100 yards with factory or premium ammo. The 5/8-24 threaded muzzle means the shorter barrel plays nicely with a suppressor if you would rather run one instead of the brake. Feeding from a 3+1 capacity with a clean two position safety, this is a purpose built hunting rig from Sheridan, Wyoming that earns its spot on a backpack hunt.

Frequently Asked Questions
How bad is the recoil on a rifle this light in .300 Win Mag?
It is far more pleasant than you would expect. The titanium Accubrake ST is rated to cut felt recoil by up to 53 percent, and the 3DHex recoil pad uses a collapsing honeycomb structure to soak up what is left. Between the two, most people find it easier on the shoulder than a heavier unbraked .300 Win Mag.
Does the Mark V Backcountry Guide come with a scope or sights?
No, this rifle ships without sights. The receiver is drilled and tapped for scope bases, and the short 54 degree bolt throw gives you plenty of hand clearance even with a low mounted scope. Plan on adding bases, rings, and glass before heading to the range.
Can I run a suppressor on the Backcountry Guide?
Yes, the muzzle is threaded 5/8-24, so you can remove the Accubrake ST and spin on a suppressor with a compatible mount. The shorter 22 inch barrel is one of the reasons the Guide series exists, since it keeps overall length reasonable with a can attached.
Is the sub-MOA accuracy guarantee real on this rifle?
It is. Weatherby guarantees every Mark V will shoot a three shot group of .99 inches or better at 100 yards from a cold barrel when using Weatherby factory or premium ammunition, within two years of verified purchase. The tensioned BSF carbon fiber barrel and zero creep TriggerTech trigger do a lot of the heavy lifting there.
