Sig Sauer Cross Magnum Sawtooth Bolt Action Rifle .300 Win Mag 6rd Magazine 24" Barrel MLOK Handguard

The Sig Sauer Cross Magnum Sawtooth bolt action rifle in .300 Win Mag is built for hunters who refuse to compromise between weight and power. This is a purpose-built long-range hunting rifle that combines a PROOF Research carbon fiber barrel with Sig's one-piece Cross Magnum receiver to deliver the accuracy and portability that high-country and backcountry hunts demand. At 8.1 pounds, it's light enough to pack mile after mile yet precise enough to ethically take game at distance.

The Sawtooth package comes out of the box configured for serious long-range work. The 24-inch stainless steel barrel is matched with a heavy profile radial brake that cuts felt recoil by up to 45 percent—a genuine advantage when shooting a magnum cartridge from a lightweight platform. The two-stage adjustable match trigger adjusts from 2.5 to 4 pounds, giving you the crisp, predictable break competitive shooters and hunters alike depend on. Sig certifies every Cross Magnum Sawtooth sub-1 MOA and ships it with a target so you can verify accuracy before heading to the field.

Modularity is built in. The lightweight M-LOK and ARCA handguard accepts slings, lights, and other accessories without adding bulk, while the 20-MOA Picatinny rail is ready for your optic. The folding precision stock collapses to 35.6 inches—a real asset if you're glassing from a vehicle or working through timber—and extends to a full 47.1 inches for a solid shooting position. The ambidextrous AR-style safety and AR-compatible grip make this rifle intuitive for shooters already familiar with modern sporting rifles. Cerakote Moss finish handles the weather, and the included 6-round AICS magazine runs reliable and fits the action cleanly.

This is a rifle for people who hunt where it matters: the mountains, the long shots, the places where every ounce and every inch of accuracy count.

Frequently Asked Questions

What makes the Cross Magnum Sawtooth different from other .300 Win Mag hunting rifles?

The carbon fiber barrel and one-piece receiver keep weight down to 8.1 pounds—light for a magnum rifle. Couple that with the certified sub-1 MOA accuracy, folding stock for backcountry packability, and modular M-LOK/ARCA handguard, and you get a rifle optimized for long-range hunting where weight and precision both matter.

Is this rifle modular? Can I add accessories?

Yes. The M-LOK and ARCA handguard accepts slings, lights, and other field accessories. The 20-MOA Picatinny rail on top is ready for your choice of optic. The handguard has dual sling attachment points, and the AR-compatible grip works with aftermarket grips and panels.

What does the sub-1 MOA certification mean, and what's included in the box?

Sig certifies every Cross Magnum Sawtooth shoots sub-1 MOA (groups smaller than one inch at 100 yards). The rifle ships with a factory target so you can verify the accuracy yourself before heading to the field.

What's the advantage of the heavy profile radial brake?

The radial brake reduces felt recoil by up to 45 percent. In a lightweight rifle chambered in .300 Win Mag, that makes a real difference in comfort and follow-up shot control, especially for hunters who shoot prone or from field positions.

How does the folding stock work, and why would I need it?

The precision stock folds to 35.6 inches and extends to 47.1 inches. It's useful for vehicles, tight spaces, and backcountry where you're moving through timber or glassing from a truck. The folding design doesn't sacrifice adjustment—the stock remains adjustable for length of pull and comb height in both positions.

What magazine does this rifle use?

The Cross Magnum Sawtooth uses AICS-pattern magazines. It comes with one 6-round double-stack steel magazine.
