SIG SAUER CROSS-243-16B-TRX (CROSS TRAX)

The SIG SAUER CROSS-243-16B-TRX (CROSS TRAX) is a lightweight bolt-action rifle chambered in .243 Winchester. It is part of the CROSS family and is designed as a compact rifle for hunting and field use, featuring a folding stock, aluminum chassis, and a 16-inch threaded stainless-steel barrel. It uses detachable AICS-pattern magazines and is built to balance portability with precision.

Specifications

Key Features

• 16-inch stainless-steel barrel for a compact overall package.
• Threaded muzzle (5/8×24) to accept compatible muzzle devices where lawful.
• Free-floating M-LOK handguard for mounting accessories and helping maintain consistent barrel harmonics.
• Folding aluminum stock that reduces transport length while retaining rigidity.
• Full-length Picatinny rail for mounting optics.
• Adjustable match trigger, allowing users to tune trigger pull within the manufacturer’s specified adjustment range.
• AICS-pattern magazine compatibility, making magazines widely available from multiple manufacturers.

Action and Trigger

The CROSS TRAX uses:

• A manually operated bolt-action system.
• A user-adjustable match trigger (approximately 1.5–4.5 lb adjustment range, depending on configuration).
• AR-style ergonomics, including a pistol grip and familiar control layout.

Dimensions

Ammunition

The rifle is chambered in .243 Winchester, a cartridge commonly chosen for:

• Medium-sized game (where lawful and appropriate)
• Predator and varmint hunting
• Recreational target shooting

Always use ammunition that matches the caliber marked on the rifle and follow the manufacturer’s recommendations.

Optics

The rifle ships with:

• A full-length Picatinny rail.
• No factory iron sights, so an optic is generally required for practical use.

Included Equipment

Depending on the retailer, the package generally includes:

• CROSS TRAX rifle.
• One 5-round Magpul AICS-compatible magazine.
• Owner’s manual.
• Cable lock.
• Factory packaging.

Advantages

• Lightweight chassis for easier carrying in the field.
• Compact 16-inch barrel and folding stock for transport and storage.
• Adjustable match trigger.
• Stainless-steel barrel for corrosion resistance.
• Free-floating M-LOK handguard.
• Broad compatibility with AICS-pattern magazines.
• Full-length optics rail.

Considerations

• The 16-inch barrel favors compactness over maximum muzzle velocity compared with longer .243 Winchester barrels.
• The rifle is supplied without sights or an optic.
• Precision and preferred ammunition can vary between individual rifles, so many owners test several factory loads to find the best-performing option. Community reports indicate the platform can be somewhat load-sensitive.

Typical Applications

The CROSS TRAX is intended for:

• Backcountry and mountain hunting.
• Predator and varmint hunting.
• Recreational precision shooting.
• General field use where a lightweight, portable bolt-action rifle is desirable.

Comparison with the Standard CROSS

The CROSS TRAX emphasizes portability while retaining the modular chassis, folding-stock design, and adjustable trigger that define the CROSS platform.
