The Nosler M48 Mountain Carbon 280 Ackley Improved rifle delivers genuine lightweight performance without the usual trade-offs between weight, accuracy, and cost. Built on the proven Nosler M48 action and topped with a 24-inch carbon fiber-wrapped barrel, this rifle achieves sub-MOA accuracy in a platform that tips the scales at just 6 pounds—light enough to carry all day in the mountains, rigid enough to shoot. The Granite Green composite stock and Tungsten Grey Cerakote finish give you a modern backcountry rifle that looks the part and handles the elements.
Every detail reflects practical engineering for the mountain hunter. The carbon-fiber reinforced Mountain Hunter stock is bedded with glass and aluminum pillars for consistency, while the Timney trigger and 2-position safety deliver reliable, crisp function. A 5/8x24 threaded muzzle accommodates suppressors or brakes, and the hinged floorplate keeps things simple in the field. At 13.5 inches of length of pull and 45 inches overall, the rifle balances naturally in your hands—precisely what you want during a long stalk.
The 280 Ackley Improved cartridge strikes a sweet spot for mountain work: enough velocity and energy for elk and similar game at distance, without excessive recoil or barrel wear. The 1-in-9 twist stabilizes modern projectiles, and Nosler backs this rifle's accuracy with a guarantee of sub-MOA groups when fired with Nosler ammunition. If you're tired of choosing between a rifle you can carry all day and a rifle you can trust to perform, this is the answer.

At 6 pounds, the M48 Mountain Carbon is genuinely light enough to carry comfortably across steep terrain without fatigue, yet the carbon fiber construction and pillar bedding maintain the rigidity needed for consistent accuracy. The 280 Ackley Improved provides sufficient power for elk and similar game at mountain distances, and the compact 45-inch overall length handles tight shooting positions among timber or rocky outcrops.
Nosler guarantees sub-MOA accuracy with Nosler ammunition, achieved through the match-grade, cut-rifled carbon wrapped barrel and precision glass-and-aluminum pillar bedding. The light Sendero contour barrel balances mass and stiffness for consistent performance without unnecessary weight.
Yes. The muzzle is threaded 5/8x24, a standard thread pitch that accommodates most modern suppressors and brakes designed for this caliber.
