The Sig Sauer Cross-Magnum Sawtooth .300 PRC 24″ 6rd is a production bolt-action rifle engineered for precision shooting and high-country hunting missions where lightweight construction and long-range capability must coexist without compromise. It pairs a 24″ Proof Research carbon fiber barrel with a one-piece Cross-Magnum receiver and a folding Cross Precision PRS stock for compact transport. Optics-ready and shipping with a 6-round steel AICS magazine, this rifle delivers consistent sub-MOA accuracy in a package that weighs 7.8 lbs as configured.

Key Features
- 24″ Proof Research Carbon Fiber Barrel — WHY IT MATTERS: Reduces weight by roughly 1.2 lbs compared to a steel barrel of the same contour, while maintaining the stiffness needed for consistent sub-MOA groups at 1,000+ yards.
- Folding Cross Precision PRS Stock — WHY IT MATTERS: Collapses to 32″ overall length for backpack carry or vehicle storage, without sacrificing cheek weld or LOP adjustability during a precision engagement.
- One-Piece Cross-Magnum Receiver — WHY IT MATTERS: Machined from a single billet of 7075-T6 aluminum, it provides a rigid, repeatable platform for the action and scope base, minimizing POI shift from environmental stress.
- Optics-Ready with 20 MOA Rail — WHY IT MATTERS: Eliminates the need for a canted base when shooting .300 PRC at extended ranges, allowing the shooter to dial elevation without maxing out the turret.
- 6-Round Steel AICS Magazine — WHY IT MATTERS: Offers reliable feeding in cold, muddy, or dusty conditions, and is compatible with aftermarket AICS-pattern mags for higher capacity if needed.
Who It’s For
This rifle is built for the precision shooter who operates in mountainous terrain—think high-country elk hunters, military snipers in alpine environments, and long-range competitors who need a sub-8 lb rifle that still prints .5 MOA. It’s not a plinker or a beginner’s gun; it’s a tool for shooters who demand repeatable accuracy from a lightweight platform.
Pros & Cons
- Pro: Sub-MOA accuracy guarantee from Sig Sauer, verified in production testing.
- Pro: Folding stock reduces storage length by 10″ for packability.
- Pro: 20 MOA rail is standard, saving you $150+ on a separate base.
- Con: The 6-round magazine capacity is adequate for hunting but limited for competition stages requiring more than 6 rounds—plan to carry spare mags.
