Description
There are lightweight rifles, and then there are rifles built from the ground up to disappear on your shoulder at 10,000 feet. The Mark V Backcountry Guide Ti sits firmly in the second camp. Weatherby started with their proven six-lug Mark V action, machined it from titanium to shave weight the steel version simply can't, then wrapped a 416R stainless barrel in BSF carbon fiber. The result is a series that starts at 5.1 pounds bare, which means even with a scope and sling you're carrying less than most rifles weigh out of the box.
Why the Guide Ti Wears a Shorter Barrel
The Guide models run trimmer barrels than the rest of the Backcountry line on purpose. The 22 inch tube keeps the rifle quick in dark timber and a lot friendlier when you spin a suppressor onto the 5/8-24 threads. Out of the box it wears Weatherby's Accubrake ST, which takes real bite out of recoil, and the 3DHex recoil pad soaks up what's left. A spiral-fluted bolt, oversized fluted handle, and an adjustable TriggerTech trigger round out the working parts, and every rifle carries Weatherby's sub-MOA three-shot guarantee.
A Purpose-Built Home for the 25 WBY RPM
This one is chambered in 25 WBY RPM, Weatherby's modern quarter-bore built around a rebated case and a fast 1:7.5 twist. It will push a 133 grain high-BC bullet around 3,000 fps, which gives you flatter trajectories and better wind performance than the classic .25s ever managed with light-for-caliber bullets. It's a legitimate deer, antelope, and sheep cartridge that still shoots soft enough to enjoy, and the 4+1 capacity feeds from a hinged floorplate.
Peak 44 Stock with Spartan Precision Built In
The Peak 44 Blacktooth stock shows off exposed carbon fiber with sponge-pattern accents, and Weatherby installs Spartan Precision gunsmithing adapters at the factory. That means Spartan's magnetic bipods and lightweight accessories snap on and off in seconds without adding hardware you don't need. If ounces matter to your hunts, this rifle was built for you.

Frequently Asked Questions
What is the 25 WBY RPM cartridge and how does it compare to the .257 Weatherby Mag?
The 25 WBY RPM is Weatherby's modern quarter-bore, built on a rebated case with a fast 1:7.5 twist so it can stabilize heavy, high-BC bullets that older .25s can't handle. It pushes a 133 grain bullet around 3,000 fps. The .257 Wby Mag is a touch faster with light bullets, but its slow twist limits it to lighter projectiles, so at longer ranges the 25 RPM can shoot flatter and buck wind better. It also fits the smaller six-lug action, which keeps this rifle lighter.
Is the Backcountry Guide Ti suppressor ready?
Yes. The 22 inch barrel comes threaded 5/8-24 and the shorter Guide-series barrel length was chosen specifically to keep the rifle manageable with a can attached. The included Accubrake ST spins off so you can mount a suppressor directly.
Does the Mark V Backcountry Guide Ti come with an accuracy guarantee?
It does. Weatherby backs every one of these rifles with a sub-MOA three-shot guarantee using factory ammunition. Between the carbon fiber barrel, titanium action, and the adjustable TriggerTech trigger, this rifle has the hardware to deliver on that promise in the field.
What do the Spartan Precision adapters on the stock do?
They're factory-installed mounting points built into the Peak 44 Blacktooth stock that accept Spartan Precision's magnetic quick-detach accessories, like their ultralight bipods and tripod mounts. You can snap a bipod on for a shot and pull it off before you start hiking again, all without carrying extra mounting hardware.
