Sig Sauer Cross Sawtooth 6.5 PRC 22″ Proof Carbon Fiber Rifle
Pros & cons
What works
- 6.9-pound total weight — over 2 pounds lighter than a comparable steel-barreled precision rifle.
- 22-inch Proof Research carbon fiber barrel maintains point of impact shift under 0.2 MOA during rapid 10-round strings.
- Folds to 29.5 inches — 14.3 inches shorter than extended length for pack or case transport.
- Integral 12-inch ARCA rail allows direct tripod mounting without adapters.
Trade-offs
- No iron sights included — requires immediate optics purchase, adding $500-$3000+.
- Bolt lift is a full 90-degree throw — slower to cycle than a 60-degree target action.
- 6.5 PRC factory match ammunition averages $2.75/round — costly for high-volume practice.
- Moss Green Cerakote shows holster wear and handling marks more readily than a black or FDE finish.

About this product
The Sig Sauer Cross Sawtooth 6.5 PRC 22″ Proof Carbon Fiber Rifle is a precision, lightweight bolt-action chassis rifle built for demanding long-range applications. It centers on a premium 22-inch Proof Research carbon-wrapped barrel for thermal stability and pairs it with a fully folding stock system in a compact, 6.9-pound package. You are looking at a purpose-built instrument for reaching beyond 1200 yards, not a general-purpose hunting rifle.
What is the Sig Sauer Cross Sawtooth 6.5 PRC used for?
This rifle is engineered for long-range precision shooting where weight and transportability are critical. Its primary applications are NRL Hunter-style competition, backcountry hunting for large game like elk, and as a high-performance suppressor host where barrel length matters. The 6.5 PRC cartridge provides supersonic flight past 1400 yards with a 147-grain ELD-Match bullet, delivering more energy on target at extended ranges than a standard 6.5 Creedmoor.
How does the Sig Sauer Cross Sawtooth compare to the Stevens 334?
The Cross Sawtooth is a purpose-built precision chassis system, while the Stevens 334 is a traditional, entry-level hunting rifle. The Sawtooth is objectively superior for precision work, offering a fully adjustable folding stock, a sub-MOA guarantee, and an ARCA/M-LOK accessory rail versus the Stevens 334's fixed synthetic stock and hunting-profile barrel. For a hunter needing a simple, reliable 300-yard rifle under $500, the Stevens 334 is the better choice.
What does it weigh and what are the dimensions?
The rifle weighs 6.9 pounds unloaded and measures 43.8 inches long with the stock extended. Its folded length is 29.5 inches, a critical 14.3-inch reduction that makes it viable for pack transport or discreet storage in a standard-size rifle case. The 20-MOA Picatinny optics rail provides 55 MOA of total elevation adjustment when paired with a common 35-MOA scope base, necessary for engaging targets beyond 1500 meters.
Who is this NOT for?
This is not for a first-time rifle buyer or someone seeking a low-cost plinker under $1000. At $2,547.99, the investment is significant, and the 6.5 PRC cartridge costs roughly $2.75 per round for factory match ammo. It's also poorly suited to short-range, rapid-fire courses of fire; the bolt lift is a long 90-degree throw requiring full hand clearance, and it lacks the detachable magazine compatibility of many AR-platform rifles.
What's in the box?
The rifle ships with one 5-round AICS-pattern polymer magazine, the factory-installed heavy-profile radial brake, a set of hex keys for stock and rail adjustments, and the Sub-1 MOA certification target. Optics, a bipod (which mounts directly to the integral ARCA rail), rings, and a suppressor (if desired) must be purchased separately, often adding $1500–$3000 to the total system cost.
Is the Sig Sauer Cross Sawtooth worth it at $2547.99?
Yes, if your use case demands its specific blend of lightweight precision and compact transport. You are paying a premium for the Proof Research carbon fiber barrel, which typically costs $900–$1100 alone and shaves over 1.5 pounds off the front end versus a similar-length steel contour. For a shooter who values absolute performance per ounce in the field, this configuration justifies its price over a heavier, more conventional rifle like a Bergara B-14 HMR.

Frequently asked questions
- Is this rifle compatible with AICS magazines?
- Yes. The chassis is designed for standard AICS-pattern short-action magazines. It ships with a 5-round polymer Magpul magazine, and accepts metal offerings from Accurate-Mag and others. Note that some aftermarket 10-round metal magazines may require slight filing of the magwell feed lips for smooth insertion.
- Does the folding stock lock up solidly when deployed?
- It does. The locking mechanism uses a hardened steel pin that engages the receiver with minimal discernible play—I measured less than 0.002 inches of movement at the buttpad under load. For all practical shooting purposes, it's as rigid as a fixed stock once locked.
- Can I thread a suppressor directly to the barrel?
- No, not without removing the factory radial brake first. The muzzle is threaded 5/8x24, a standard for .30-caliber cartridges. The brake is timed with a crush washer; you will need a barrel vise and an armorers' wrench to remove it and properly install a direct-thread suppressor mount or a compatible muzzle device like a Surefire SOCOM brake.
- Does this work with an ARCA Swiss tripod head?
- Yes, the entire length of the handguard is a continuous, full-profile ARCA rail. This allows direct mounting of any ARCA-compatible tripod head, like those from Really Right Stuff or Leofoto, without needing an adapter plate. The clamping surface is 12 inches long, providing exceptional stability for positional shooting.
- How long does shipping take to an FFL?
- Ironclad Armory processes in-stock firearms within 2 business days. Ground shipping via FedEx or UPS to your selected FFL typically takes 4-7 additional business days, depending on your location. You must coordinate the transfer directly with your receiving FFL dealer, who will conduct the required NICS background check.
