SIG Sauer Cross Magnum “Sawtooth” .300 Win. Mag. Bolt-Action Rifle – Carbon-Fiber PROOF Barrel, Folding Chassis, Flat Earth/Moss-Green
The Cross Magnum Sawtooth is SIG Sauer’s long-range, magnum-rated take on the original Cross platform. This rifle pairs a 24-inch PROOF Research carbon-fiber-wrapped barrel with a one-piece 7075 aluminum chassis finished in flat earth and moss-green Cerakote. A folding, fully adjustable stock, integral 0 MOA/20 MOA Picatinny rail, and full-length ARCA underside make this lightweight magnum an immediately capable precision hunting or target system.

Built around SIG’s one-piece receiver, the Cross Magnum eliminates the traditional action-chassis interface, increasing rigidity while shaving weight. The integral Picatinny rail offers both 0 MOA and 20 MOA cant, giving shooters immediate flexibility for optic setup.
The 24-inch, heavy-contour PROOF Research barrel is carbon-fiber wrapped 416R stainless steel, threaded 5/8-24, and fitted with a radial muzzle brake. The 1:9–1:10 twist stabilizes a wide range of .300 Win. Mag. projectiles, and the carbon-fiber construction keeps the front end light for field carry.
Its skeletonized aluminum stock folds alongside the bolt, reducing overall length for transportation. Adjustable cheek height, butt-pad, and a 13.5-inch length of pull let the shooter custom-fit the rifle on the spot.
The right-hand bolt uses a 60-degree lift and an oversized knob for fast cycling, feeding from detachable AICS magazines. A two-stage, user-adjustable trigger and ambidextrous safety lever round out the precision-focused, shooter-friendly controls.
