Chambered in 6.5 Creedmoor and mounted on MDT’s HNT26 chassis system, this rifle delivers sub-MOA performance out of the box.

Weight lands at 6.5 pounds bare (per manufacturer specs), making it a serious tool for backcountry and high-angle work.

Key Features
- MDT HNT26 Chassis: This isn’t a stock—it’s a full aluminum chassis with carbon fiber forend, pistol grip, and buttstock. Why it matters: you get true chassis adjustability (length of pull, cheek riser, LOP) without the weight penalty of a full metal chassis. Ideal for mountain hunting where every ounce counts.
- BSF Carbon Fiber Barrel (22″): BSF wraps a stainless steel core in carbon fiber, reducing barrel weight by roughly 30% over a comparable steel barrel. Why it matters: faster target acquisition, less fatigue on long stalks, and better heat dissipation for sustained strings of fire.
- Weatherby Accubrake DST: Dual-stage tactical muzzle brake, threaded 5/8×24. Why it matters: reduces recoil by up to 65% (per Weatherby specs), allowing you to spot your own hits and stay on target for follow-up shots.
- AICS Magazine Compatibility: Accepts standard AICS-pattern magazines (ships with one 5-round mag). Why it matters: widely available, affordable, and reliable—no proprietary mags to hunt down.
- 6.5 Creedmoor Chamber: Factory-chambered with a 1:8 twist rate. Why it matters: the 6.5 CM is the gold standard for long-range hunting—flat trajectory, high ballistic coefficient, and manageable recoil. This barrel is optimized for 140-grain projectiles.
Who It’s For
This rifle is built for the disciplined field shooter—law enforcement, military, or serious hunter who needs a lightweight, precision-oriented platform that can be carried all day and shot accurately at distance. If you’re packing into the backcountry or working a patrol rifle that doubles as a hunting tool, the Alpine MDT Carbon fits that role. It’s not a range toy; it’s a tool for making one-shot kills at extended ranges.
Pros & Cons
Pros: Sub-7-pound weight with full chassis adjustability; BSF carbon barrel is accurate and lightweight; Accubrake DST is effective and tunable; AICS mags are easy to source; Weatherby’s reputation for accuracy holds.
Cons: The Accubrake DST is loud—expect more muzzle blast than a standard brake or suppressor host. Also, the carbon fiber forend can feel slick in wet conditions without aftermarket grip tape. Not a dealbreaker, but worth noting if you hunt in rain or snow.
