Sig Sauer CROSS24316BTRX Cross Trax 243 Win 5+1 16" Stainless Threaded Barrel, Black Anodized Picatinny Rail Alloy Steel Receiver, M-LOK Handguard, Black Minimalist Folding Stock, Black Polymer Grip

The Sig Sauer CROSS Trax in 243 Win is a lightweight, modern rifle built for hunters and shooters who value portability without sacrificing precision. Built on Sig's proven CROSS platform, this 243 Winchester delivers flat-shooting performance in a compact, packable design that works equally well in a truck rack, on a backcountry hunt, or at the range. The stainless steel barrel is precision-made and threaded, giving you the option to run a suppressor or muzzle device—and that 1:9 twist keeps bullets stable across a wide range of 243 loads.

What sets the CROSS Trax apart is its obsessive attention to weight and modularity. The alloy steel receiver is black anodized for durability and low visibility in the field. The handguard features M-LOK slots throughout, letting you mount lights, bipods, or sling attachments exactly where you need them. The minimalist folding stock is the real game-changer: fully deployed, you get a functional length of pull; fold it, and overall length drops to just 26 inches—perfect for tight spaces, vehicles, or when you need to move fast. The lightweight skeletonized design and low-profile bolt knob keep snags out of the equation. You're looking at just 6.1 pounds with magazine, making this one of the quickest-handling 243s on the market.

The two-stage match-grade trigger is user-adjustable, so you can dial in the break that feels right for your shooting style. With a 5-round magazine and that hunting-appropriate 243 Winchester punch, the CROSS Trax bridges the gap between a lightweight AR-platform rifle and a traditional bolt-gun—giving you modern ergonomics and controls in a chassis that actually gets carried all day.

Frequently Asked Questions

Is this rifle suitable for long-range hunting?

The 243 Winchester is a proven medium-range hunting cartridge with a flat trajectory and minimal recoil, making it excellent for deer, antelope, and similar game out to several hundred yards depending on your ammunition and shooting skill. The stainless barrel and two-stage trigger support accurate shooting, and the threaded muzzle lets you add a suppressor for field control.

Can I customize the handguard and add accessories?

Yes. The M-LOK slots throughout the skeletonized handguard accept industry-standard mounts for lights, bipods, sling adapters, and other gear. The Picatinny rail on the receiver accepts any standard optic mount.

How short does this rifle get when the stock is folded?

When fully folded, the CROSS Trax measures 26 inches overall, making it easy to store in vehicles, tight spaces, or carry in confined environments where a standard rifle won't fit.

What trigger pull options are available?

The two-stage match-grade trigger is user-adjustable, allowing you to customize the break to your preference. Factory settings are designed for precision shooting, but you can dial it to suit your needs.
