Sig Sauer Cross Caliber X-Change Kit 6.5 Creedmoor 18" 1:8 Twist 5/8x24 Stainless Barrel

The Sig Sauer Cross Caliber X-Change Kit is a factory barrel replacement system designed for the Sig Cross bolt-action rifle platform. This kit allows Cross owners to swap chamberings without sending the rifle to a gunsmith, giving shooters the flexibility to change between supported calibers using Sig Sauer's proprietary barrel mounting system.

This particular kit is chambered in 6.5 Creedmoor and features an 18" stainless steel barrel with a 1:8 twist rate optimized for stabilizing a wide range of match and hunting bullet weights. The barrel is finished in stainless for corrosion resistance in adverse conditions and threaded 5/8x24 for compatibility with standard muzzle devices and suppressors.

The Caliber X-Change Kit ships complete with the barrel, barrel extension, barrel nut, and thread protector cap, providing every component needed to re-barrel an existing Cross rifle to 6.5 Creedmoor. This is a factory Sig Sauer part and a direct-fit replacement for the original Cross barrel.
