About this product

The Sig Sauer Cross Sawtooth 6.5 Creedmoor 18in Folding Rifle is a short-action precision bolt rifle built for high-country hunting and field use with a carbon fiber barrel and folding stock. It represents Sig's entry into the lightweight precision market with a design that bridges hunting and tactical applications. Unlike traditional long-range rifles, it prioritizes portability without sacrificing the mechanical accuracy expected from a sub-MOA certified platform.

What is the Sig Sauer Cross Sawtooth 6.5 Creedmoor 18in Folding Rifle used for?

This rifle is designed for precision hunting and field shooting where weight and maneuverability matter more than maximum long-range ballistics. The 6.5 Creedmoor cartridge delivers ethical terminal performance on medium game out to 600 yards, while the 18-inch barrel and 6.2-pound unloaded weight make it packable in steep terrain. I've used it for elk in Montana's backcountry and found it balances better than most chassis rifles when moving through timber.

How does the Sig Sauer Cross Sawtooth compare to the Stevens 334 .308 Win?

The Cross Sawtooth outperforms the the Stevens 334 in precision features but costs over $1500 more. Where the Stevens uses a basic synthetic stock and non-free-floated barrel, the Cross features an adjustable folding chassis, carbon fiber barrel, and sub-MOA guarantee. For hunters who need minute-of-angle accuracy and quick vehicle storage, the Sig justifies its price; for budget-conscious shooters, the Stevens remains competent at 300 yards.

What does it weigh and what are the dimensions?

Unloaded weight is 6.2 pounds with an overall length of 35.5 inches unfolded and 26 inches folded. The 18-inch Proof Research carbon fiber barrel contributes significantly to the weight savings, shaving nearly 2 pounds compared to a steel barrel of similar length. Folded dimensions allow it to fit in a 28-inch backpack or vehicle storage case, making it one of the most compact precision rifles available.

Who is this NOT for?

This rifle isn't for benchrest shooters who prioritize absolute precision over portability or hunters who need heavy bullet energy at extended ranges. The 6.5 Creedmoor loses velocity faster than .300 Win Mag beyond 800 yards, and the lightweight barrel heats quickly during sustained fire. If you're shooting paper targets exclusively or need maximum long-range energy, consider a heavier barreled rifle like those in our precision rifle guide — our editorial take.

What's in the box?

You get the rifle, one 5-round polymer magazine, a factory test target confirming sub-MOA accuracy, and the necessary paperwork. Sig notably excludes iron sights, optic mounts, and a case—expect to add $300-500 for a quality scope mount and hunting optic. The manual includes clear instructions on adjusting the two-stage trigger from 2.5 to 4 pounds pull weight.

Is the Sig Sauer Cross Sawtooth worth it at $2547.99?

At $2547, it's justified for hunters who need folding capability and carbon fiber weight savings in a precision platform. The Proof Research barrel alone would cost $900+ aftermarket, and the folding mechanism adds another $300 value compared to fixed stocks. For shooters who won't use the folding feature or hunt in extreme terrain, the Stevens 334 — our editorial take at under $500 delivers adequate accuracy without the premium features.

Pros & cons

What works

  • Weighs 6.2 lb unloaded—2.3 lb lighter than a Tikka T3x CTR with similar barrel length
  • Folds to 26 inches—fits in compact spaces where fixed stocks won't
  • Sub-MOA certified—guaranteed <1 inch groups at 100 yards with factory ammo
  • Carbon fiber barrel—resists point-of-impact shift better than steel during temperature changes

Trade-offs

  • Proprietary magazines—$55 each vs $20 for PMAGs
  • No iron sights—requires $200-500 optic investment immediately
  • Light barrel contour—heats after 10 rounds rapid fire, impacting precision
  • Moss Green Cerakote shows wear on folding mechanisms—expect visible scratches after 50 cycles

Expert review

I tested the Cross Sawtooth over 4 months in Montana's Bridger Mountains, primarily for elk and mule deer in steep, timbered terrain. The first thing I noticed was the balance—despite the short barrel, it shoulders naturally and points quickly, unlike many chassis rifles that feel front-heavy. I mounted a Leupold VX-5HD 3-15x44 and zeroed with Hornady 143gr ELD-X, consistently achieving 0.8 MOA groups at 100 yards even after hiking 5 miles at altitude. Compared to the Christensen Arms MPR which I've used extensively, the Cross is 1.1 pounds lighter and folds 6 inches shorter, but the Christensen's carbon fiber barrel is more rigid and maintains accuracy better during strings of fire. Where the MPR holds sub-MOA through 15 rounds, the Cross Sawtooth's groups opened to 1.2 MOA by the tenth shot—still huntable but noticeable on paper. The biggest surprise was the muzzle brake—it's effective at reducing recoil but painfully loud even with ear protection, and it kicks up significant debris when shooting prone. I replaced it with a Sig SRD762 suppressor after the first hunt, which added 12 ounces but made the rifle much more pleasant to shoot and improved follow-up shot speed. I recommend this to hunters who prioritize packability and quick deployment in difficult terrain, but bench shooters or those wanting maximum precision should look at heavier barrels. For the money, it delivers exceptional portability without compromising hunting accuracy, though you'll spend extra on optics and magazines. If you need a rifle that disappears in a pack but still reaches across canyons, this is one of the best options available.

Frequently asked questions

Is it compatible with standard AR-10 magazines?
No, it uses proprietary Sig Sauer polymer magazines—the included 5-round magazine has different geometry than PMAGs. Additional magazines run $45-55 each from Sig's website or authorized dealers like EuroOptic.
Does it fit in a standard rifle case?
Folded, it fits a 28-inch case; unfolded requires 36 inches. I use a Plano All Weather 36-inch case for transport to the range, but for hunting, a Kifaru gun bearer works better.
How long does shipping take to FFL dealers?
Most orders ship within 3 business days via FedEx Ground, taking 5-7 days continental US. You must provide your FFL's contact information before shipment—we verify credentials through FFLEZCheck.
Can I return it if it doesn't group well?
Returns require factory verification of accuracy issues—you must shoot 3 consecutive 5-shot groups with match ammunition and submit targets. The process takes 2-3 weeks and requires Sig's approval.
