Description
Weatherby built the 307 Range CS Carbon around a simple idea: give folks a modern, carbon-barreled bolt gun that feels custom without the custom wait or custom headaches. It rides on the Model 307 action, Weatherby's first all-new action in over 50 years, which uses a 2-lug, fully cylindrical design that plays nicely with the massive aftermarket built around the Remington 700 footprint. That means your choice of stocks, triggers, rails, mounts, and AICS-pattern magazines will drop right in down the road if you ever feel the itch to tinker.
The heart of this one is the barrel. It's a BSF carbon-fiber-wrapped barrel measuring 18 inches, built on a 416R stainless core with a roll-wrapped carbon sleeve that sheds weight and helps the barrel shed heat between strings. The muzzle wears an Accubrake threaded 1/2×28, so it's suppressor-ready right out of the box, and that brake tames a good chunk of the 7mm PRC's recoil. Overall length with the brake installed runs right around 20 inches, which makes for a short, lively package that balances well and doesn't fight you in tight cover or off a truck seat.
What the 307 Range CS Carbon Brings to the Bench
Up top you get a drilled and tapped receiver finished in Graphite Black Cerakote, so mounting the glass of your choice is straightforward. The TriggerTech trigger breaks clean with zero creep and adjusts down light for precise work, and the two-position safety and M16-style extractor keep things dependable in the field. Weatherby backs every 307 with a sub-MOA accuracy guarantee using factory or premium ammo, which tells you where their confidence sits.
Why 7mm PRC Suits This Build
The 7mm PRC has quickly become a favorite for long-range hunters, throwing high-BC bullets flat and fast with manageable recoil for the performance you get. Out of this handy 18-inch carbon barrel, it's a serious open-country elk and deer rifle that still carries easy. The adjustable comb and length-of-pull let you dial the fit to you, and the textured vertical grip stock keeps things planted in cold or wet hands. It's a genuine crossover rifle, equally at home ringing steel at distance or packed into the high country.

Frequently Asked Questions
Is the Weatherby 307 Range CS Carbon barrel threaded for a suppressor?
Yes. The 18-inch BSF carbon barrel comes threaded 1/2×28 from the factory and ships with an Accubrake installed. You can run the brake as-is or swap in a suppressor or other compatible muzzle device.
What magazines does the 307 Range CS Carbon use?
It ships with one 5-round Magpul magazine and feeds from AICS-pattern magazines. That means replacements and spares are easy to find, and you've got plenty of aftermarket options for different capacities and materials.
Does the Weatherby 307 Range CS Carbon come with any accuracy guarantee?
Weatherby backs every Model 307 with a sub-MOA accuracy guarantee, meaning a sub-inch group at 100 yards with factory or premium ammunition. It's a solid sign of confidence in the carbon-barreled build and the bedding of the action.
Can I mount a scope on the 307 Range CS Carbon, and is it Remington 700 compatible?
The receiver is drilled and tapped, so you can mount the base and rings or a rail of your choice. The Model 307 action uses the Remington 700 footprint, so most 700-pattern bases, bottom metal, and accessories will fit.
