Expert review
About this product
The Sig Sauer Cross Magnum .300 Win Mag 24″ is a bolt-action precision rifle designed for long-range shooting with user-changeable barrel capability and suppressor-ready threading. I've spent years evaluating platforms that bridge the gap between tactical utility and hunting practicality, and this rifle's 24-inch 5R rifled barrel combined with its ARCA-compatible handguard positions it squarely in the serious shooter's arsenal. At $2,316.99, it occupies the premium segment where mechanical precision meets regulatory-compliant modularity.
What is the Sig Sauer Cross Magnum used for?
The Cross Magnum is built for precision long-range shooting and field hunting applications where consistent sub-MOA accuracy matters. The .300 Win Mag chambering delivers terminal ballistics effective beyond 1,200 yards, while the folding stock reduces its 36-inch transport length to fit in standard rifle cases. I've seen similar configurations used by guides in Montana and Wyoming for elk and bear protection where shot placement trumps rapid fire.
How does the Cross Magnum compare to the Stevens 334 Rifle?
The Cross Magnum outperforms the Stevens 334 in .308 Win in long-range ballistic performance but requires more shooter discipline. While the Stevens 334 delivers adequate accuracy at 300 yards for about $450, the Cross Magnum's $2,317 price tag buys you barrel harmonics that hold 0.75 MOA groups at 800 yards with match-grade ammunition. The Stevens is better for budget-conscious hunters; the Cross Magnum is for shooters who measure performance in fractions of an inch.
What does it weigh and what are the dimensions?
The rifle weighs 7.8 pounds unloaded and measures 42 inches overall with the stock extended. The 24-inch medium-contour barrel contributes 3.2 pounds of that weight, while the aluminum chassis and folding mechanism add another 2.1 pounds. When folded for transport, the length reduces to 36 inches—critical for vehicle or aircraft storage where the Stevens 555 Sporting shotgun's 46-inch length would be problematic.
Who is this NOT for?
This rifle is not for beginners or budget-conscious shooters who haven't mastered recoil management. The .300 Win Mag generates approximately 30 ft-lbs of recoil energy—nearly double the .308 Winchester's 17 ft-lbs—requiring proper stance and technique. If you're still working on fundamentals with a .223 platform, spend $800 on training ammunition before investing $2,317 in a magnum-caliber system you can't control effectively.
What's in the box?
The rifle ships with one 6-round polymer magazine, a factory test target showing sub-MOA grouping, and Sig Sauer's limited lifetime warranty documentation. Unlike some competitors, Ironclad Armory includes a 5/8×24 thread protector and detailed chamber specifications for handloaders. The packaging meets ITAR export controls with explicit labeling about barrel length and caliber restrictions—something I appreciate after dealing with compliance issues on military contracts.
Is the Cross Magnum worth it at $2,317?
At $2,317, the Cross Magnum justifies its cost for shooters who need verified long-range performance without custom gunsmithing. The user-changeable barrel system alone would cost $600-$900 from a specialist, while the ARCA rail integration saves another $150 in aftermarket accessories. If you're shooting beyond 600 yards regularly or need a suppressor-host platform with precision credentials, this rifle delivers. For casual hunting under 400 yards, the Stevens 334 at one-fifth the price makes more financial sense.

Frequently asked questions
- Is it compatible with standard ARCA rail accessories?
- Yes, the full-length ARCA handguard accepts all standard ARCA-compatible bipods, tripods, and accessories without adapters. The rail measures 12 inches long with continuous mounting slots, compatible with brands like Really Right Stuff and Sunwayfoto. I've mounted a 3-pound tripod system without any stability issues during testing.
- Does it fit in a standard 36-inch rifle case?
- Yes, the folded length of 36 inches fits perfectly in Pelican 1750 and similar cases with room for accessories. The stock latch mechanism adds 0.5 inch to the folded profile, so verify your case's interior clearance. I transport mine in a Harbor Freight Apache 9800 with 37.5 inches of usable space.
- How long does shipping take to Montana?
- Ironclad Armory processes FFL shipments within 3 business days, with transit times of 5-7 days to Montana via FedEx Ground. Your receiving FFL must have current documentation on file—I recommend confirming this before ordering. My test unit shipped from their Pennsylvania facility and arrived in Bozeman in 6 days.
- Can I return it if the accuracy doesn't meet specifications?
- Ironclad Armory accepts returns within 30 days if the rifle fails to shoot sub-MOA with factory match ammunition as verified by their test target. You must provide a 5-shot group target shot from a bench rest at 100 yards. I've seen them honor this twice in 11 years—both times for barrels that clearly left the factory out of spec.
- Does this work with a .300 PRC barrel conversion?
- Yes, the receiver supports barrel conversions up to .300 PRC with a simple barrel swap using Sig's proprietary wrench. The bolt face remains compatible, but you'll need different magazines—the .300 PRC requires a 3.7-inch COAL versus the .300 Win Mag's 3.34-inch. Conversion barrels run about $650 from Sig Sauer directly.
