Nosler M48 Mountain Carbon 300 Win Mag Rifle - Gray Finish

The Nosler M48 Mountain Carbon in 300 Win Mag is a long-range hunting rifle engineered to prove you don't have to sacrifice accuracy, reliability, or your bank account for a genuinely lightweight mountain gun. Built on the proven Nosler M48 action and topped with a 24-inch carbon fiber-wrapped barrel, this rifle delivers sub-MOA accuracy at 6 pounds—light enough to carry all day without feeling like dead weight, but stiff and rigid enough to shoot like a rifle built for serious distance.

The barrel itself is match-grade cut-rifled and wrapped in carbon fiber, a combination that shaves ounces while maintaining the stiffness needed for precision. Glass and aluminum pillar bedding locks the barreled action into a carbon fiber Mountain Hunter stock finished in Shale Gray, and all steel surfaces wear a Tungsten Grey Cerakote finish that stands up to weather and hard use. The 1-in-10 twist rate is optimized for the 300 Win Mag's velocity range, and you get a hinged floorplate with a 3-round magazine capacity, plus a 5/8x24 threaded muzzle for suppressor or brake options. A Timney trigger with a two-position safety rounds out the package.

If you hunt elk, mule deer, or other western game where pack-in miles matter and shots can stretch past 400 yards, the M48 Mountain Carbon bridges the gap between ultralight compromise rigs and full-size precision rifles. It's built to handle the 300 Win Mag's recoil and velocity without flinching, and Nosler backs its accuracy guarantee with sub-MOA performance when you feed it Nosler ammunition. At 45 inches overall and balanced like an extension of your arm, this is a rifle that earns its weight in the field.

Frequently Asked Questions

What ammunition does the M48 Mountain Carbon shoot?

This rifle is chambered in 300 Win Mag and is guaranteed sub-MOA accuracy when loaded with Nosler ammunition. It will chamber and fire standard 300 Win Mag ammunition from other manufacturers, but Nosler's accuracy guarantee specifically applies to their loads.

Is this rifle suitable for long-range hunting?

Yes. The 300 Win Mag is a proven magnum cartridge for elk and other large game, and the M48 Mountain Carbon's match-grade barrel and precise bedding support consistent accuracy at extended range. The lightweight profile makes it practical for high-elevation hunts where pack-in distance is a factor.

Can I attach a suppressor or muzzle brake?

The rifle comes with a 5/8x24 threaded muzzle, which is a common suppressor and muzzle brake thread pattern. You can use any suppressor or brake with that threading.

What is the length of pull, and will it fit me?

The stock has a 13.5-inch length of pull. If you have a significantly different build or prefer a longer or shorter LOP, you may want to handle the rifle before purchasing or discuss stock modifications with Nosler.
