Description
The Sig Sauer Cross Trax 308 is the lightest, shortest rifle in the Cross family, built for people who measure a rifle by how far they are willing to carry it. MAG5 Firearms stocks this Trax configuration with a 16-inch threaded barrel, a skeletonized M-LOK handguard, a minimalist folding stock and an adjustable trigger.
Built Around Weight, Not Bench Rest Scores
Trax is the trimmed-down branch of the Cross line. The handguard is skeletonized rather than solid, the stock is a minimalist folder rather than a full adjustable chassis, and the barrel is 16 inches instead of 20 or 24.
Every one of those decisions saves weight. The Sig Sauer Cross Trax 308 is a rifle you can carry up a mountain and still shoot well when you get there, which is a different problem from shooting well off a bench.
Sig Sauer Cross Trax 308 Barrel Length and 308 Winchester
Three-oh-eight is the cartridge that handles a short barrel best among common centerfires. It burns efficiently, so a 16-inch tube gives up far less velocity than a magnum would, and factory ammunition is available everywhere in every bullet weight.
The threaded muzzle takes a brake or a suppressor, and a suppressor on a rifle this short is a genuinely practical setup rather than a compromise.

The Folding Stock and Transport
Folded, the rifle fits across a pack or into a case that does not announce a rifle. That matters for travel, for vehicle storage and for getting into a spot without catching brush with a full-length gun.
The stock locks solidly when deployed. Folding stocks earned a bad reputation decades ago, and the Sig Sauer Cross Trax 308 is a reminder that the engineering caught up a long time ago.
Adjustable Trigger and Optics Mounting
The trigger adjusts for pull weight, so the rifle can be set up for gloved hunting use or lighter target work without a replacement unit.
An integrated optic mount removes the scope base as a separate component. Fewer parts in the load path between scope and barrel means fewer things to work loose in the field.
