SIG SAUER CROSS Magnum .300 Winchester Magnum Rifle

Description

SIG SAUER CROSS Magnum .300 Winchester Magnum Rifle

The SIG SAUER CROSS Magnum expands the CROSS bolt-action platform for hunters and precision shooters who need magnum-class capability. Chambered in .300 Winchester Magnum, this configuration uses a 24-inch barrel, a six-round detachable AICS-pattern magazine, and a purpose-built magnum receiver. Its aluminum coyote-anodized frame, folding adjustable precision stock, and full-length ARCA/M-LOK handguard create a field-ready system that can be configured around the shooter, optic, support equipment, and intended hunt.

Manufacturer part number CROSSMAG300WM24B is the standard coyote CROSS Magnum configuration. SIG SAUER lists the rifle at 45.2 inches overall and 8.9 pounds with the magazine installed, balancing the stability expected from a magnum rifle with a design intended to remain manageable in the field.

24-Inch Magnum Barrel

The 24-inch user-changeable barrel uses 5R rifling and a 1:9-inch twist selected for the .300 Winchester Magnum chambering. Its muzzle is threaded 5/8×24 and fitted with an integrated radial compensator. According to SIG SAUER, the compensator design reduces felt recoil from the magnum cartridge by as much as 45 percent, helping the shooter maintain a more controlled position and recover a sight picture more efficiently.

The barrel and receiver arrangement was also engineered so the barrel can be changed without requiring removal of the scope and Picatinny rail. That design supports long-term serviceability while keeping the optic interface attached to the receiver assembly.

Adjustable Folding Stock

A folding adjustable precision stock allows the rifle to be tailored for individual fit and more compact transport. Adjustability helps establish a repeatable cheek position and length of pull when the rifle is paired with different optics, clothing layers, or shooting positions. SIG SAUER redesigned the Magnum’s folding hinge for stronger lockup, improved stock retention, and easier operation.

The forward-angle precision-rifle-style grip and right-side thumb rest provide a natural interface from supported positions. An ambidextrous safety keeps the primary control accessible from either side, while the two-stage adjustable match trigger gives the shooter a defined take-up and break suited to careful field or range work.

Support and Optic Integration

The free-floating handguard incorporates full-length ARCA and M-LOK mounting surfaces. ARCA compatibility supports direct use with many tripods, clamps, and shooting supports, while M-LOK slots provide space for a bipod or other compatible accessories. The continuous adjustment range makes it easier to position support equipment for balance rather than being limited to a small number of fixed mounting points.

An integrated Picatinny optics rail provides the mounting surface for a suitable riflescope. The rifle is optic ready and does not include an optic, so buyers can select glass and rings appropriate for .300 Winchester Magnum recoil, expected shooting distance, and environmental conditions.

Setup Considerations

Before field use, mount and torque the selected optic and support accessories according to their manufacturers’ specifications, then verify zero with the intended ammunition. The adjustable stock should be fitted to the shooter while maintaining safe muzzle direction and an unloaded chamber. Routine inspection of the action, magazine, muzzle device, mounting hardware, and stock hinge helps keep the rifle configured consistently for repeatable use.

Built for Demanding Field Use

The CROSS Magnum combines the reach and energy of .300 Winchester Magnum with a chassis-style rifle that supports modern optics, tripods, bipods, and individualized fit. Its magazine-fed action, adjustable stock, recoil-mitigating muzzle device, and adaptable handguard make it well suited to backcountry hunting, long-range practice, and precision-oriented field use. Firearm transfer requirements and local laws apply; the rifle must be shipped to an eligible receiving FFL where required.
