Sig Sauer Cross Sawtooth Short Action Rifle .308 Win 5rd Magazine 16" 5/8x24 Barrel Moss Green

The Sig Sauer Cross Sawtooth short-action rifle in .308 Winchester delivers sub-MOA precision in a compact, highly configurable platform built for hunters and shooters who demand reliability without compromise. This 16-inch barreled rifle combines a user-changeable Proof Research carbon fiber barrel with Sig's reputation for match-grade accuracy, giving you a lightweight, versatile hunting rifle that doesn't sacrifice performance for portability. At 6.5 pounds, it's genuinely packable for backcountry hunts or long days glassing ridgelines, yet it's engineered to compete on the range and perform in the field.

The standout feature here is the modular design: swap barrels without gunsmithing, giving you flexibility to experiment with different twist rates or explore other cartridges down the road. The 2-stage adjustable match trigger breaks cleanly and consistently, while the AR-compatible grip interface lets you tailor ergonomics to your hand. The folding adjustable stock saves length when packed but extends to a full shooting position, and the heavy radial muzzle brake tames recoil—important in a lighter rifle chambered for a powerful cartridge like .308 Win. Finished in Moss Green Cerakote, it looks as ready for adventure as it performs.

Sig backs this rifle with a sub-MOA accuracy guarantee (target included), so you'll know exactly what you're starting with out of the box. The 5-round magazine and short-action design keep things nimble, whether you're hunting elk in tight timber or working a precision match. If you're after a modern, reconfigurable hunting rifle that doesn't compromise on accuracy or weight, the Cross Sawtooth is worth your attention.

Frequently Asked Questions

Is the barrel really swappable without a gunsmith?

Yes. The Sig Sauer Cross Sawtooth features a user-changeable Proof Research carbon fiber barrel, so you can swap barrels yourself without sending the rifle to a gunsmith. This modularity is one of the platform's biggest advantages if you want to experiment with different calibers or twist rates over time.

What accuracy can I expect out of the box?

Sig guarantees sub-MOA accuracy with the Cross Sawtooth, and includes a target so you can verify the rifle's performance immediately. That's a real commitment to precision and a practical baseline for both hunting and range work.

Will this rifle work with standard AR grips and accessories?

The rifle uses an AR-compatible reduced angle grip, so it integrates with the AR ecosystem for ergonomics and controls. This gives you flexibility if you're already familiar with AR-pattern furniture or want to customize the grip to your preference.

Is this rifle suitable for hunting, or is it primarily a range gun?

The Cross Sawtooth is purpose-built as a hunting rifle. Its 16-inch barrel, lightweight 6.5-pound weight, and folding stock make it genuinely portable for backcountry and field use, while the sub-MOA accuracy and .308 Win power serve most North American hunting applications effectively.
