The Sig Sauer Cross MAG 300WM bolt-action rifle is a precision magnum platform built for hunters and long-range shooters who demand modularity without sacrificing accuracy or portability. At 8.9 lbs with the magazine installed, this 24-inch stainless steel rifle in 300 Winchester Magnum delivers the power you need for big game and distant targets while remaining manageable in the field or vehicle. The one-piece receiver design keeps groups tight, and the quick-change barrel system means you can adapt to different missions without breaking down your rifle—a rare feature in this class.
What sets the Cross MAG apart is the marriage of modern ergonomics with genuine modularity. The folding precision stock collapses to just 36 inches overall, making it ideal for truck racks, overlanding rigs, or hunts where space is tight. The full-length ARCA handguard gives you unlimited mounting options for bipods, lights, or tactical accessories, while the M-LOK rail system integrates seamlessly with modern gear. The PRS-style grip with right-side thumb rest safety is intuitive under pressure, and the 2-stage match trigger breaks clean for repeatable, accurate shots.
Sig's Coyote anodized finish delivers durability and a professional look that doesn't scream for attention in the field. The 300 Win Mag chambering is proven, widely available, and capable of ethical shots well beyond 1000 yards when you do your part. One 6-round AICS-pattern steel magazine comes included—a dependable, industry-standard setup that leaves room for aftermarket upgrades if you want them. Whether you're glassing from a remote camp, setting up precision rifle practice, or hunting where terrain demands a compact rig, the Cross MAG gives you magnum performance in a package that actually works in the real world.
