Proof Research Sig Sauer Cross Pre-Fit Barrel – 6.5 Creedmoor – 16" Carbon Fiber
The Proof Research Sig Sauer Cross Pre-Fit Barrel (134504) is a premium, drop-in upgrade designed to elevate the performance of the innovative Sig Cross rifle. While the factory Sig Cross is already highly regarded for its portability, this 16-inch carbon fiber-wrapped barrel allows owners to further reduce weight while significantly increasing the rifle's thermal performance and long-range precision. By utilizing Proof’s aerospace-grade carbon fiber wrapping around a 416R stainless steel core, this barrel offers the rigidity of a much thicker profile with the weight savings necessary for a backcountry mountain rifle.
Specifically chambered in 6.5 Creedmoor with a fast 1:8 twist rate, this barrel is optimized for stabilizing high-BC (ballistic coefficient) projectiles, ensuring match-grade accuracy for both hunters and competitive shooters. Because it is a true pre-fit design, it is guaranteed to headspace correctly and can be installed by the user with minimal specialized tools—eliminating the need to send the rifle to a gunsmith for a custom re-barrel. The muzzle comes pre-threaded in 5/8x24 TPI, making it ready for your favorite suppressor or muzzle brake immediately out of the box.
Note: This barrel is specifically designed for the Sig Sauer Cross action. Professional installation or the use of appropriate torque tools is recommended to ensure safety and performance.
