Key Features
- BSF Carbon Fiber Barrel (22″) — WHY IT MATTERS: The shorter length saves weight and improves maneuverability in tight cover, while the carbon fiber wrap dissipates heat faster than steel, maintaining accuracy during multiple follow-up shots.
- Titanium Accubrake ST — WHY IT MATTERS: This machined, lightweight muzzle brake reduces felt recoil by up to 53% compared to an unbraked barrel, letting you spot your own impacts without shifting position.
- TriggerTech Adjustable Trigger — WHY IT MATTERS: You can dial pull weight from 2.5 to 5.0 pounds without removing the action, giving you a crisp, creep-free break for precision shooting in hunting conditions.
- Peak 44 Blacktooth Stock with 3DHex Recoil Pad — WHY IT MATTERS: The stock integrates a Spartan Precision gunsmithing adapter for quick bipod or tripod mounting, and the 3DHex pad further tames .240 Wby Mag recoil, keeping you on target.
- Left-Hand Threaded Muzzle — WHY IT MATTERS: Left-handed shooters get a factory-threaded barrel (5/8-24) for direct suppressor attachment, eliminating the need for aftermarket threading and preserving accuracy.
Who It’s For
This rifle is built for the left-handed backcountry hunter who values weight savings without sacrificing long-range precision. It’s suited for mountain hunts, high-country stalks, and pack-in trips where every ounce counts. The .240 Weatherby Magnum chambers flat-shooting 85-100 grain bullets, making it ideal for deer, pronghorn, and similar game at distances beyond 400 yards. If you’re a competition shooter transitioning to hunting, the TriggerTech trigger and carbon barrel give you the same edge you’d expect from a precision rig.
Pros & Cons
- Pros: Sub-6-pound weight with full carbon fiber barrel; factory-threaded muzzle for suppressors; TriggerTech trigger is adjustable without tools; Spartan Precision adapter adds modularity.
- Cons: The .240 Weatherby Magnum has limited factory ammunition availability compared to .243 Win or 6.5 Creedmoor; the 22″ barrel reduces velocity by ~100 fps vs. a 26″ tube, which may affect extreme-range trajectory.

| Weight | 5.8 lbs | 7.2 lbs | 8.6 lbs |
| Barrel | 22″ BSF Carbon Fiber | 22″ Carbon Fiber | 22″ Steel (fluted) |

The Weatherby is lighter than the Christensen and Bergara, but the Christensen offers a comparable carbon barrel at a lower price. The Bergara is heavier but more affordable and has a wider aftermarket. For left-hand shooters, the Weatherby is one of the few production rifles with a factory left-hand threaded muzzle and a carbon fiber barrel.
FAQ
What is the effective range of the .240 Weatherby Magnum in this rifle?
With a 22″ barrel, the .240 Weatherby Magnum pushes 100-grain bullets at approximately 3,200 fps. Effective range for deer-sized game is 500-600 yards, depending on bullet selection and shooter skill. The Accubrake ST helps with recoil management for extended shooting sessions.
Does this rifle come with a scope base or rings?
No, the rifle is sold without optics. It has a factory-drilled and tapped receiver with 8-40 screw holes, compatible with Picatinny rails or two-piece bases from brands like Talley or Leupold. Plan to add a rail and rings for your preferred optic.
Can I use a suppressor with the threaded muzzle?
Yes, the left-hand threaded muzzle is 5/8-24, a common suppressor thread pitch. The titanium Accubrake ST can be removed to attach a direct-thread suppressor. Ensure your suppressor is rated for .240 Weatherby Magnum pressures.
Is the stock adjustable for length of pull or cheek height?
The Peak 44 Blacktooth stock is a fixed-length design. It does not have an adjustable cheekpiece or length of pull spacers. However, the 3DHex recoil pad is removable, and you can install a custom pad to adjust length of pull if needed.
How does the TriggerTech trigger adjust?
Use a 3/32″ hex key to turn the adjustment screw located inside the trigger housing. Turn clockwise to increase pull weight (up to 5 lbs) and counterclockwise to decrease (down to 2.5 lbs). No need to remove the action from the stock.
