Sig Sauer Cross 8901360 Cal-X Kit 308 16

The Sig Sauer Cross 8901360 Cal-X Kit 308 16 is a factory barrel assembly designed for shooters who want quick caliber conversion on their Cross platform rifle. This stainless steel barrel swap kit lets you pivot from .308 Winchester to another caliber—or vice versa—without swapping the entire rifle. If you run a Cross and want versatility for different hunting seasons, game types, or range applications, a dedicated barrel kit eliminates the need to own two complete firearms.

Sig Sauer engineered the Cross around modularity, and this 16-inch barrel assembly is the core of that flexibility. The stainless construction stands up to field use and weather, and the 16-inch length strikes a balance between maneuverability in brush or from a vehicle and enough velocity for effective .308 Winchester ballistics. Whether you're switching between whitetail and elk seasons, or adapting your rifle for different shooting disciplines, a barrel kit keeps your platform current without the cost and complexity of a second gun.

This is a genuine Sig Sauer factory component, not an aftermarket tube. That means fit, headspace, and reliability are engineered to Cross specifications. Barrel swaps on the Cross are straightforward—no gunsmithing required—so you can make the switch in minutes and get back to shooting.
