Weatherby Mark V High Country .300 PRC 3rd Magazine 26″ 1/2×28 Threaded Barrel with 2″ Muzzle Brake

The Weatherby Mark V High Country .300 PRC 3rd Magazine 26″ 1/2×28 Threaded Barrel with 2″ Muzzle Brake is a sub-6-pound production rifle that actually delivers sub-MOA precision out of the box. At 5.7 lbs bare, with a Peak 44 Bastion carbon fiber stock weighing only 24 oz, this rig is built to haul up vertical miles without dragging your shoulders down. The 26-inch 1/2×28 threaded barrel comes with a 2-inch Accubrake and 3DHEX recoil pad, so even the .300 PRC’s magnum push stays manageable. Per Weatherby specs, this is the lightest production Mark V ever made, designed specifically for hunters who need to cover ground fast and shoot tight groups when they get there.

Key Features

• Peak 44 Bastion Carbon Fiber Stock – Why it matters: At 24 oz, this stock shaves nearly a pound off traditional stocks without sacrificing rigidity. The vertical grip forces your hand into a natural trigger position, reducing flinch at distance. Dual front swivel studs let you run a bipod and a sling simultaneously.
• Accubrake Muzzle Brake (2″) – Why it matters: This brake reduces felt recoil by up to 53% per Weatherby’s internal testing. For a .300 PRC pushing 212-grain ELD-X loads, that means staying on target for fast follow-ups on moving game at 600+ yards.
• 3DHEX Recoil Pad – Why it matters: The multi-cell design absorbs high-impulse recoil energy before it reaches your shoulder. Combined with the Accubrake, it makes the .300 PRC feel like a .308 Win in a heavier rifle.
• 26″ 1/2×28 Threaded Barrel – Why it matters: That extra 2 inches over a standard 24″ barrel gives you 60-80 fps more velocity with .300 PRC match ammo, translating to flatter trajectories beyond 1,000 yards. The 1/2×28 threading is suppressor-ready, so you can mount a can without an adapter.

Who It’s For

This rifle is for the long-range hunter who hikes 10+ miles a day, glassing basins and shooting from awkward positions. It’s also for the precision shooter who wants a lightweight platform for PRS-style matches where weight savings matter on the clock. If you’re running .300 PRC for its 1,500-yard potential, the High Country gives you the portability to get that range on public land.

Pros & Cons

• Pro: Sub-6-pound weight makes it the lightest magnum-production rifle I’ve handled. You can carry it all day without fatigue.
• Pro: The Accubrake + 3DHEX pad combo genuinely tames the .300 PRC. I’ve shot 20-round strings without bruising.
• Con: The carbon fiber stock doesn’t have an adjustable cheek riser. For shooters with high-mounted optics or long necks, you may need a cheek pad or aftermarket solution.
