The Weatherby 307 Alpine MDT Carbon .300 PRC 22in is a precision bolt-action rifle built on the proven Model 307 platform, integrating a BSF carbon-wrapped barrel and an MDT HNT26 carbon chassis for long-range consistency. Chambered in .300 PRC, this rifle delivers sub-MOA accuracy out of the box, with a 22-inch barrel and Weatherby Accubrake DST to manage recoil and keep you on target. It folds for compact carry and feeds from AICS-pattern magazines. This is a dedicated precision tool for shooters who demand repeatable performance in field or match conditions.

Key Features
- BSF Carbon Barrel — The 22-inch, 1:10 twist carbon-wrapped barrel reduces weight by nearly 1.5 pounds over steel without sacrificing stiffness, allowing faster follow-up shots and less fatigue on long hikes to the firing line.
- MDT HNT26 Carbon Chassis — A foldable buttstock and full-length aluminum bedding block give you a rock-solid foundation for consistent cheek weld and repeatable zero retention, even after multiple folds.
- Weatherby Accubrake DST — Integrated dual-stage muzzle brake cuts .300 PRC recoil by up to 40%, keeping the sight picture stable and reducing shooter fatigue during extended strings.
- AICS Magazine Compatibility — Uses standard AICS-pattern magazines (5+1 capacity) so you aren’t locked into proprietary mags; swap between 5- and 10-round options without modification.
- Model 307 Action — Two-lug, 90-degree bolt throw with a floating bolt head and integral recoil lug delivers consistent primary extraction and smooth cycling under heavy use.
Who It’s For
This rifle is for the precision shooter who operates in austere environments — law enforcement marksmen, military snipers, and serious long-range competitors who need a lightweight, foldable platform that holds zero through rough handling.
Pros/Cons
- Pro: Sub-MOA guarantee out of the box with quality match ammunition; verified in field tests at 300 yards.
- Pro: Foldable stock reduces overall length to 34 inches for pack transport or vehicle storage.
- Pro: BSF carbon barrel stays cooler longer than steel, extending accuracy during rapid fire.
- Con: The 22-inch barrel limits muzzle velocity by roughly 50-75 fps compared to a 26-inch .300 PRC barrel, which may matter at extreme ranges beyond 1,500 yards.

FAQ
What twist rate does the barrel have?
The barrel has a 1:10 twist rate, optimized for .300 PRC bullets from 200 to 230 grains.
Can I use standard .300 Win Mag magazines in this rifle?
No. The rifle accepts only AICS-pattern magazines designed for .300 PRC. Standard .300 Win Mag magazines may not feed reliably due to case length differences.
Is the chassis compatible with aftermarket triggers?
Yes. The MDT HNT26 chassis accepts standard Remington 700 footprint triggers, including Timney and Geissele units, but we recommend testing for proper sear engagement.
Does the foldable stock lock securely?
Yes. The MDT HNT26 chassis uses a positive-locking hinge with a steel latch that returns to zero within 0.5 MOA after repeated folding.
What is the overall length when folded?
When folded, the rifle measures 34 inches from muzzle to buttpad, making it compact enough for backpack or vehicle storage.
