Sig Sauer CROSS Magnum .300 Win Mag 24″ 6-Round Elite Earth
Pros & cons
What works
- Quick-change barrel system enables caliber swaps in under 20 minutes.
- Folds to 35.2 inches—shorter than many tactical shotguns like the Stevens 555 Sporting.
- Carbon fiber barrel saves ~2 lbs versus steel while maintaining stiffness for sub-MOA accuracy.
- Integrated full-length ARCA rail for direct, secure tripod mounting.
Trade-offs
- High price of $2,187.99 demands significant additional investment for optic and mount.
- Single included 6-round magazine; additional AICS mags cost $45-$80 each.
- Elite Earth Cerakote is durable but shows wear on hinge points and muzzle after hard field use.
- Lacks the traditional aesthetic; is strictly a modern, modular tool.

About this product
The Sig Sauer CROSS Magnum .300 Winchester Magnum rifle is a purpose-built, modular long-range hunting platform designed for extreme precision and rapid transport. Engineered from its one-piece receiver down to its 24-inch carbon fiber barrel, this rifle prioritizes cartridge flexibility and mechanical stability in a package that folds to just over 35 inches. Its quick-change barrel system and full-length M-LOK/ARCA handguard make it a distinctly modern alternative to traditional bolt-action hunting rifles.
What is the Sig Sauer CROSS Magnum used for?
The CROSS Magnum is used for long-range hunting of large North American game and precision field shooting where shot distances frequently exceed 500 yards. It is built for the hunter who must cover miles of backcountry but still demands sub-MOA accuracy for an ethical kill. The folding stock and 8.7-pound weight make it packable, while the .300 Win Mag cartridge provides the necessary terminal energy for elk, moose, and bear at extended ranges.
How does the Sig Sauer CROSS Magnum compare to the Stevens 334?
The CROSS Magnum is a more modular, technically advanced rifle better suited for custom long-range builds than the Stevens 334. While the Stevens 334 in .308 Winchester is a reliable, no-frills entry-level hunting rifle, the CROSS offers a superior feature set: a quick-change barrel system for caliber swaps, a full-length integrated ARCA rail for tripod mounting, and a robust folding mechanism. The Stevens is better for a simple, low-cost, 200-yard deer rifle; the CROSS is for the serious hunter or shooter investing in a system for 1000-yard capability.
What does it weigh and what are the dimensions?
The rifle weighs 8.7 pounds (approximately 3.95 kg) in the .300 Win Mag configuration with the 24-inch barrel. The overall length with the stock extended is 44.5 inches; folding the aluminum stock reduces that to 35.2 inches for transport or storage. The carbon fiber barrel contributes significantly to this balance, shaving nearly 2 pounds off a comparable steel barrel while maintaining stiffness.
Who is this NOT for?
This rifle is not for the budget-conscious new shooter or someone looking for a classic wood-stocked hunting rifle. The $2,187.99 price point places it in a different league than budget-friendly options like the Stevens 334. Furthermore, its modular, tactical aesthetic and focus on accessory mounting via M-LOK and ARCA rails will not appeal to hunters seeking a traditional walnut-and-blue steel look.
What's in the box?
The rifle ships with one polymer 6-round AICS-pattern magazine, a set of Torx wrenches for the handguard and stock hardware, and the owner's manual with Sig Sauer's warranty registration card. Notably, it does not include a scope mount, rings, or any form of optic, which must be purchased separately and will add a minimum of $200-$400 to the total system cost.
Is the Sig Sauer CROSS Magnum worth it at $2,187.99?
Yes, the CROSS Magnum is worth it for the specific shooter who needs a lightweight, packable, and wildly accurate rifle system capable of handling magnum cartridges. You are paying for the engineering: the quick-change barrel system, the rigid one-piece receiver, the carbon fiber barrel, and the robust folding hinge. For anyone who will actually use those features to swap calibers, mount a heavy thermal scope, or pack it into remote wilderness, the investment is justified. For someone who won't, it's excessive engineering.

Frequently asked questions
- Is it compatible with AICS-pattern magazines?
- Yes. The CROSS Magnum uses standard AICS-pattern short-action magnum magazines. The included polymer magazine is a Sig-branded version, but you can use metal magazines from manufacturers like Accuracy International or Magpul, which typically hold 5 or 10 rounds of .300 Win Mag.
- Does the barrel system work with other calibers?
- Yes, the quick-change system is central to the design. Sig Sauer offers pre-fit barrels in several calibers, including 6.5 Creedmoor and .308 Winchester. A barrel swap requires the proprietary tool, available from Sig Sauer Armorer Works, and can be completed by a competent shooter in approximately 15 minutes following the manual.
- Does the handguard fit standard ARCA-Swiss plates?
- Yes, the handguard features a full-length, integrated ARCA-Swiss rail. It will accept any standard ARCA clamp from manufacturers like Really Right Stuff or RRS, which have a standard dovetail width of 38mm. This is essential for secure mounting to a tripod for long-range stability.
- How long does shipping take for firearms?
- All firearm shipments from Ironclad Armory require 3-5 business days for order processing and compliance verification before they are released to your selected FFL dealer. Once shipped via FedEx, transit time is typically 2-3 additional business days. You will be notified via email at each step.
