Description
The Sig Sauer Cross-Magnum Sawtooth 7mm PRC 24in Carbon 6rd is a purpose-built bolt-action rifle for high-country hunting and precision field work. It combines a one-piece Cross-Magnum receiver with a 24-inch Proof Research carbon fiber barrel, delivering sub-MOA accuracy in a lightweight, packable platform. The folding stock and ARCA/M-LOK handguard make it ready for glass-bedded bipods, tripods, or sling carry straight from the box.

Key Features
- Proof Research carbon fiber barrel (24 in.) – Reduces weight by roughly 30% compared to a steel barrel of the same contour, letting you hike farther without fatigue while maintaining match-grade accuracy.
- One-piece Cross-Magnum receiver – Machined from a single billet of aluminum, this receiver eliminates the tolerance stack-up of two-piece designs, keeping your scope zero locked in even after folding the stock.
- Adjustable folding precision stock – Length of pull and cheek height adjust without tools, and the folding mechanism lets you pack the rifle into a 30-inch bag for backcountry travel or vehicle storage.
- Lightweight ARCA/M-LOK handguard – The integrated ARCA rail accepts quick-detach bipods and tripod heads, while M-LOK slots let you mount a light or foregrip without adding rail weight.
- Moss-green Cerakote-style finish – Provides corrosion resistance and a low-glare surface that blends into alpine, forest, and prairie environments.
Who It’s For
This rifle is built for the hunter who hikes miles above treeline for elk, mule deer, or sheep and demands a rifle that shoots as well from a pack frame as it does from a bench. It also fits the precision rifle competitor who wants a 7mm PRC platform that transitions fast between positions without sacrificing wind-bucking ability. If you carry a suppressor, the 24-inch barrel keeps velocity high while staying short enough for a can.
Pros & Cons
Pros
– Sub-MOA guarantee with match ammunition, verified by Sig Sauer warranty.
– Folding stock reduces packed length to under 30 inches, fitting in most airline-approved cases.
– ARCA rail is standard, saving you $100–$200 on aftermarket rail upgrades.
– 7mm PRC delivers 175-grain bullets at 3,000+ fps, matching .300 Win Mag energy with less recoil.
Cons
– The carbon fiber barrel can heat up faster than a heavy steel barrel during rapid-fire strings; let it cool between groups for best accuracy.
– 6-round magazine capacity may require a reload for extended hunting scenarios, though spare AICS mags are widely available.
