The Weatherby Mark V APEX LH .300 Weatherby Magnum FDE is a factory-built, left-handed bolt-action rifle that brings together Weatherby’s proven Mark V action with a lightweight Peak 44 Bastion carbon-fiber stock. Chambered in .300 Weatherby Magnum, this rifle is built for long-range hunting and field use without the extra weight that usually comes with a magnum setup. The two-tone Cerakote barrel, fluted bolt, and Accubrake ST muzzle brake make it a solid choice for anyone who wants to shoot accurately and stay on target.

Key Features
- Peak 44 Bastion Carbon-Fiber Stock — Keeps the rifle light at 6.5 pounds, so you can carry it through a long day in the field without feeling like you’re lugging a log.
- Accubrake ST Muzzle Brake — Cuts recoil noticeably, letting you spot your own hits and stay on glass for follow-up shots.
- TriggerTech Trigger — Crisp, adjustable pull that breaks clean every time, giving you confidence when the shot matters most.
- Spiral-Fluted Bolt and Barrel — Reduces weight and helps the barrel cool faster between shots, keeping your groups tight.
- 3DHEX Recoil Pad — Soaks up the remaining punch from the .300 Wby Mag, making it comfortable to shoot at the range or in the field.
Who It’s For
This rifle is for the left-handed shooter who wants a factory-built, long-range hunting rig that doesn’t require a gunsmith. It’s a good fit for anyone who hunts elk, moose, or big mule deer out West, where you might need to reach out past 400 yards. Newer shooters who are ready to step up to a magnum will appreciate the muzzle brake and recoil pad that tame the .300 Weatherby Magnum. It also works well for the hunter who wants a lightweight setup for mountain hunting without giving up accuracy.
Pros & Cons
- Pro: Lightweight carbon-fiber stock makes it easy to carry all day.
- Pro: Factory-built, no waiting for a custom build.
- Pro: Accubrake ST and 3DHEX pad make the .300 Wby Mag manageable.
- Con: The .300 Weatherby Magnum ammunition is more expensive than standard .308 or .30-06, so practice sessions will cost more.

The Weatherby Mark V APEX LH is a complete rifle, while Timney and Geissele triggers are aftermarket upgrades you’d install on an existing rifle. If you want a turnkey long-range setup, the APEX is ready out of the box. If you already have a rifle and just want a better trigger, those brands are good options.
What is the barrel length on the Weatherby Mark V APEX LH .300 Weatherby Magnum?
Per Weatherby specs, the barrel length is 24 inches with a two-tone Cerakote finish and a spiral fluted contour. It’s threaded to accept the included Accubrake ST muzzle brake.
Is this rifle available in right-hand configuration?
This specific model is the left-hand (LH) version. Weatherby also offers the Mark V APEX in right-hand for the same caliber and stock configuration. Check our product category for both options.
Does the stock have adjustable length of pull or cheek riser?
The Peak 44 Bastion stock on the APEX has a fixed length of pull and a low-profile cheekpiece. It’s designed to keep weight down while still providing a solid cheek weld. If you need adjustability, look at the Weatherby Mark V Backcountry or a custom chassis.
What is the magazine capacity?
The Weatherby Mark V APEX LH uses a hinged floorplate with a 3+1 capacity. It’s a traditional blind magazine setup for reliability and weight savings.
Can I mount a scope directly to the receiver?
Yes, the receiver is drilled and tapped for standard Weatherby bases or Picatinny rails. You’ll need to buy rings or a one-piece mount separately. We recommend Talley or Leupold bases for this action.
