Description
The Weatherby Mark V APEX .300 Weatherby Magnum Rifle brings together the proven Mark V steel action with lightweight materials built for long days in the backcountry. Chambered in the hard-hitting .300 Weatherby Magnum, this bolt-action rifle weighs just 7.50 lbs and comes ready for precision field use. According to Weatherby spec sheets, the APEX configuration uses a Peak 44 Bastion carbon-fiber vertical-grip stock and a fluted, two-tone Cerakote barrel to cut weight without sacrificing accuracy. The TriggerTech Field trigger breaks crisp and clean, while the Accubrake ST muzzle brake tames recoil so you can spot your own hits. If you need a rifle that carries light and shoots flat past 500 yards, the Weatherby Mark V APEX .300 Weatherby Magnum Rifle is a strong candidate.

Key Features
- Peak 44 Bastion carbon-fiber vertical-grip stock – Why it matters: Saves significant weight over traditional stocks and gives you a natural, repeatable hand position for steady offhand shots and prone work.
- Fluted two-tone Cerakote barrel – Why it matters: Reduces barrel weight and surface heat buildup while the Cerakote finish resists rust and glare in wet or sunny conditions.
- TriggerTech Field trigger – Why it matters: Delivers a clean, creep-free break with zero take-up, helping you stay on target during the critical moment of the shot.
- Weatherby Accubrake ST muzzle brake – Why it matters: Cuts felt recoil by roughly 50%, letting you shoot faster and stay behind the scope for follow-up shots.
- Enhanced bolt fluting – Why it matters: Smoother cycling under heavy loads and reduces overall bolt weight, speeding up your reloads in the field.
Who It’s For
This rifle is built for the hunter who walks miles for elk, mule deer, or bear and wants a lightweight rig that still reaches out with authority. It also suits the precision rifleman who needs a flat-shooting magnum for steel targets past 600 yards. If you’re used to carrying a 9-lb rifle and want to shed weight without losing the Mark V’s reliability, the APEX is your ticket.
Pros / Cons
- Pros: Sub-8-lb weight with a full-size magnum action; excellent trigger out of the box; effective muzzle brake; carbon-fiber stock is stiff and weatherproof.
- Cons: The .300 Weatherby Magnum round is expensive and can be hard to find in rural stores. The Accubrake ST is loud and may require ear protection even in the field.
