SIG SAUER CROSS TRAX .308 Winchester 16-Inch Bolt-Action Rifle

The SIG SAUER CROSS TRAX is a compact, lightweight .308 Winchester bolt-action rifle built for hunters who need a capable field rifle without unnecessary bulk. This exact black configuration is manufacturer part number CROSS-308-16B-TRX, UPC 798681690268. It combines the proven CROSS receiver with a shorter handguard, minimalist folding stock, compact bolt handle, and a 16-inch stainless-steel barrel to create a portable platform for backcountry hunts, dense terrain, vehicle transport, and general-purpose field use.

Compact CROSS TRAX Configuration

SIG SAUER designed the CROSS TRAX around a reduced overall footprint. The rifle measures approximately 35.1 inches with the stock extended and about 26 inches with the stock folded. Its listed weight is approximately 5.9 pounds before an optic and accessories are installed. That combination helps keep the rifle manageable on long hikes and makes it easier to stow than a conventional fixed-stock hunting rifle.

The lightweight minimalist stock folds at the receiver and includes an integrated sling-QD location and polymer cheek piece. An AR-compatible PDW-style grip supplies a familiar control angle, while the low-profile bolt knob and handle are shaped to reduce snagging on clothing, packs, and other field equipment. The stock should be fully locked in its operating position before firing, and the rifle should always be carried and stored according to the SIG SAUER owner’s manual.

16-Inch .308 Winchester Barrel

The CROSS TRAX uses a 16-inch stainless-steel barrel with a 1:10-inch twist rate. The compact barrel keeps the rifle balanced while supporting a broad range of commonly available .308 Winchester hunting and target ammunition. Muzzle threads are specified as 5/8-inch-24 with SIG’s tapered shoulder, and the rifle is supplied with a thread protector and taper cap. Any muzzle device must be compatible with the thread and shoulder geometry and should be installed according to the device manufacturer’s instructions.

Optics and Accessory Support

A factory 20-MOA Picatinny receiver rail provides a solid mounting surface for a suitable riflescope. The added elevation bias can be useful when configuring an optic for longer-distance applications, while still supporting conventional hunting setups. The free-floating 11.5-inch skeletonized aluminum handguard uses M-LOK attachment slots, allowing the owner to add compatible accessories without replacing the forend. Optic, rings, bipod, sling, and other accessories are not included unless specifically stated elsewhere in the listing.

Trigger, Safety, and Feeding System

The rifle features a curved, two-stage adjustable match trigger with a factory-specified adjustment range of approximately 2.5 to 4 pounds. Its ambidextrous AR-style manual safety is positioned for access from either side. The CROSS TRAX feeds from AICS-pattern magazines and includes one 5-round polymer magazine. Magazine fit and function should be checked before field use, particularly when using additional aftermarket AICS-pattern magazines.

Field-Oriented Design

The CROSS TRAX is especially well suited to buyers who prioritize packability and weight. Its folding stock reduces storage length without requiring the action or barrel to be separated, and the streamlined handguard leaves room for the accessories most hunters actually use. The .308 Winchester chambering supports a wide selection of commercial ammunition, although ammunition should always be selected for the intended game, distance, and local regulations.

Responsible Ownership

Read the complete SIG SAUER CROSS operator’s manual before loading or firing this rifle. Keep the muzzle pointed in a safe direction, keep the safety engaged until ready to fire, and keep the trigger finger outside the trigger guard until the sights are on the target and the decision to fire has been made. Confirm the barrel is unobstructed, use only correct factory-loaded ammunition in good condition, and have any installation or repair beyond routine owner maintenance performed by a qualified gunsmith. Transfer, magazine, hunting, and transport rules vary by jurisdiction, so current requirements should be confirmed before purchase and use.

For hunters seeking a compact .308 bolt-action rifle with modern ergonomics, the SIG SAUER CROSS TRAX combines a lightweight folding chassis, threaded stainless barrel, adjustable match trigger, and flexible optics and accessory mounting in a purpose-built field package.
