Description
The Weatherby 307 Alpine MDT Carbon 308 is the most practical rifle in the Alpine MDT family. It puts the Model 307 action and a 20 inch BSF carbon wrapped barrel into an MDT HNT26 folding chassis, chambered for the one cartridge you can buy anywhere. Weight is 6.5 pounds bare, it folds to 29.25 inches and extends to 42.25 inches, and capacity is three rounds. The UPC is 747115456741. MAG5 Firearms lists it for hunters who want chassis ergonomics without a magnum ammunition bill.
Chassis Features Without the Chassis Weight
The mdt hnt26 chassis is built from carbon fiber and magnesium instead of aluminum billet, and that single decision is why a folding chassis rifle here weighs six and a half pounds rather than ten. Comb height and length of pull both adjust, length of pull runs 12.5 to 13.5 inches, and the forend carries an integrated ARCA rail so a tripod clamp or ARCA bipod mounts with no adaptor at all.
Folding matters more than the spec sheet suggests. At 29.25 inches folded the Weatherby 307 Alpine MDT Carbon 308 goes inside a pack rather than lashed to the outside, fits behind a truck seat and clears a bush plane door. The hinge locks tightly enough that folding and unfolding does not shift zero, which is the difference between a chassis and a stock with a hinge bolted on.
Underneath is the Weatherby Model 307: two lugs, an M16 style extractor, tool-less bolt disassembly for cleaning in camp and a Remington 700 footprint so aftermarket bases, triggers and chassis all fit. The trigger is an externally adjustable TriggerTech field unit. The bsf carbon barrel is a steel liner inside a carbon shell with a 1 in 10 twist and an Accubrake DST fitted to a 5 8 by 24 thread.
Why 308 Is the Smart Pick Here
Everything expensive about this rifle is aimed at saving weight and adding adjustability. Putting a mild, universally available cartridge behind that gives you a lightweight 308 hunting rifle you will actually shoot, and a Weatherby 307 Alpine MDT Carbon 308 is a rifle you will practice with. 308 Winchester is stocked in every gun shop in the country, in every bullet weight, and it will cleanly take anything a 30 caliber should be used on inside sensible ranges.
The 20 inch barrel costs very little. 308 was designed around barrels in this range and the velocity difference against 22 inches is small enough to ignore at hunting distances. What a Weatherby 307 Alpine MDT Carbon 308 gains instead is a rifle that clears brush, folds shorter and balances neutrally. With the Accubrake DST fitted, recoil from a Weatherby 307 Alpine MDT Carbon 308 is genuinely mild, and many owners fit the thread protector instead and accept a firmer push to keep the noise down.
Two honest caveats. A carbon wrapped barrel saves weight and nothing else, so confirm zero in two or three round groups with real cooling time rather than shooting long strings. And a chassis is colder and harder in the hand than a composite stock, with a vertical grip that takes some getting used to if you have only shot sporters. Neither is a flaw in a Weatherby 307 Alpine MDT Carbon 308, but both are worth knowing before you buy.

Who Should Buy It
A Weatherby 307 Alpine MDT Carbon 308 suits the hunter who packs a rifle rather than slings it, shoots off a tripod or a pack, and wants ammunition they can buy on the road without planning. It is the version of this rifle most people should actually own. Full factory specifications are published by Weatherby.
If you want a flatter trajectory for open country, the 257 Weatherby Magnum version of the same chassis rifle reaches further at the cost of ammunition price and barrel life. If you want a conventional carbon stock and a lower price, look at the 307 Alpine CT in 308 Winchester. Browse the rest of our rifles to compare.
Practical notes. Buy two or three spare AICS pattern magazines, because they are cheap and a chassis invites carrying them. Choose a light scope with honest elevation travel and rings matched to the supplied rail, because a heavy optic cancels the point of a Weatherby 307 Alpine MDT Carbon 308. And because the action is a 700 footprint, later upgrades are easy, so start with good glass rather than accessories.
