Sig took everything people liked about the original Cross and scaled it up for serious magnum cartridges. The Cross Magnum is built around a one-piece machined aluminum receiver strong enough to handle long-action rounds up to 300 PRC, and this version wears a 24 inch stainless steel medium-contour barrel in .300 Win Mag with 5R rifling and a 1:10 twist. The barrel is user-changeable, so as aftermarket options grow you can rebarrel or swap calibers at home instead of shipping the rifle off to a gunsmith. Up front, the muzzle is threaded 5/8×24 and ships with a brake to tame the recoil, or you can spin on a suppressor.
At 8.9 pounds with the magazine, this rifle sits in a sweet spot. It is light enough to haul up a mountain all day, but has enough heft to stay in the glass and shoot comfortably with full-power .300 Win Mag loads. The redesigned folding stock hinge drops the overall length from 45.2 inches down to roughly 36 inches folded, which makes a real difference strapping it to a pack or sliding it into a truck. The precision stock adjusts for length of pull and comb height, so getting a proper cheek weld behind a big scope takes seconds, not shims.
The full-length free-floating handguard runs M-LOK slots and an integrated ARCA rail the entire way down, so clipping into a tripod or ballhead is instant, no adapter plates needed. The forward-angled PRS-style grip and the right-side thumb rest safety keep your firing hand planted through the shot. A crisp two-stage match trigger rounds out the package, and feeding comes from a detachable 6-round AICS-pattern steel magazine. Reviewers have run this rifle to 1,000 yards and beyond with factory hunting loads, which tracks with what the .300 Win Mag has been doing on elk ridges and firing lines for decades. If you want one rifle that hunts hard and still holds its own at long range, this one earns its spot in the safe.
No, it ships without sights and is set up as an optics-ready rifle. Given the long-range capability of the .300 Win Mag and the 24 inch barrel, most owners top it with a quality variable scope in the 3-18x or 5-25x range. Plan your mount and rings around the receiver rail when you order.
It is lighter than a dedicated precision rig but heavier than a featherweight mountain rifle, and that balance works. The included muzzle brake takes a lot of the sting out, and the adjustable stock lets you set up proper body position behind the rifle. Most people who shoot it find the recoil very manageable for the cartridge.
Yes, the quick-change barrel system is one of the platform's biggest draws. The receiver was designed for user barrel swaps with basic tools, and it can accommodate cartridges up to 300 PRC in length. That means you can rebarrel when your bore wears out or set up the same rifle for a different chambering down the road.
It feeds from AICS-pattern detachable box magazines and includes one 6-round steel mag from the factory. The AICS pattern is one of the most common in the precision rifle world, so spare magazines are easy to find from Sig and plenty of third-party makers.
