If you’re a left-handed shooter who hunts the wide-open spaces of the West or stretches things out on a 1,000-yard range, this Weatherby Mark V BC Carbon in 6.5×300 Weatherby Mag is exactly what you need. It’s a lightweight, high-velocity bolt gun that pairs a 26-inch BSF carbon fiber barrel with a carbon-fiber stock finished in Patriot Brown Cerakote. The result is a rifle that carries easy but shoots like a heavy custom rig. Per Weatherby specs, the 6.5×300 Weatherby Mag pushes a 140-grain bullet over 3,300 fps, giving you flat trajectories and serious energy downrange. This Weatherby Mark V BC Carbon 6.5×300 26-inch LH comes drilled and tapped for optics, with a TriggerTech trigger that breaks clean and crisp.

Key Features
- BSF carbon fiber barrel (26-inch): Why it matters — this barrel sheds weight without sacrificing stiffness, so you get a rifle that’s easy to carry all day but still holds tight groups shot after shot.
- TriggerTech trigger: Why it matters — a clean, adjustable trigger pull means you can place your shots with confidence, even when the wind is howling or your heart rate is up.
- Left-hand action and left-hand threaded muzzle (5/8×24): Why it matters — it’s built for southpaws from the ground up, and the threaded barrel lets you add a brake or suppressor without needing a gunsmith.
- Carbon fiber stock with Patriot Brown Cerakote: Why it matters — the stock is rigid and weather-resistant, and the Cerakote finish protects against scratches, moisture, and rough field use.
- Drilled and tapped receiver: Why it matters — mounting optics is straightforward, so you can get your scope on and get to the range fast.
Who It’s For
This rifle is built for the left-handed hunter or long-range shooter who wants a lightweight rig that can reach out past 600 yards. It’s ideal for mountain hunts, pronghorn trips, or anyone stepping into the 6.5×300 Weatherby Mag cartridge. If you’re a new gun owner looking for a do-it-all rifle that’s easy to carry and accurate, this is a solid choice — just plan on spending time behind the trigger to learn the mild recoil and flat trajectory.
Pros & Cons
- Pros: Very light weight (around 6.5 lbs), excellent accuracy potential, left-hand action and threaded barrel, TriggerTech trigger, Patriot Brown Cerakote finish is durable and looks sharp.
- Cons: Ammunition for 6.5×300 Weatherby Mag can be pricey and harder to find at local shops compared to more common calibers like .308 Win. Also, the carbon fiber barrel may heat up faster during rapid fire strings — not an issue for hunting or careful range work, but something to note for high-volume sessions.

Note: Geissele and Timney make excellent products, but they serve different roles. The Weatherby is a dedicated long-range bolt gun, while Geissele’s rifle is a gas-operated carbine. Timney’s trigger is an aftermarket part, not a complete rifle. For a left-handed shooter wanting extreme velocity and light weight, the Weatherby Mark V BC Carbon is in a class of its own.
FAQ
Is this rifle compatible with suppressors?
Yes. The barrel is left-hand threaded with a 5/8×24 pattern, which fits most common rifle suppressors and muzzle brakes designed for .30-caliber and smaller. Just make sure your suppressor supports the 6.5×300 Weatherby Mag pressure levels.
What optics mounting system does it use?
The receiver is drilled and tapped for standard scope bases. Weatherby recommends using quality rings and bases from brands like Talley or Leupold. You’ll need a set that fits the Mark V action.
Is this rifle good for left-handed shooters only?
It’s built specifically for left-handed shooters — the action, bolt handle, and ejection port are all reversed. Right-handed shooters should look at the standard right-hand version of the Mark V BC Carbon.
What is the effective range of the 6.5×300 Weatherby Mag?
With a 140-grain bullet at 3,300+ fps, the 6.5×300 Weatherby Mag is a 1,000-yard cartridge. It retains high velocity and energy well past 500 yards, making it excellent for long-range hunting and target shooting.
