Description
The Proof Research Pre-Fit Bolt Action Barrel is a precision drop-in replacement barrel engineered specifically for the Sig Sauer Cross bolt-action rifle. Chambered in .260 Remington, this 18-inch barrel features Proof Research’s signature carbon fiber-wrapped construction, delivering improved heat dissipation and notable weight savings over traditional all-steel barrels.
The barrel is cut with a 1:8 inch twist rate and a 5-groove bore, a configuration well-suited to the .260 Remington’s bullet weight range. The muzzle is threaded 5/8×24 to accept a broad selection of muzzle brakes, compensators, and sound suppressors. The pre-fit, drop-in design means no gunsmithing is required – shooters can swap or change calibers on their Sig Cross platform quickly and confidently.
Finished in Proof Research’s distinctive carbon fiber wrap, this Pre-Fit barrel installs directly onto the Sig Cross action. Whether you are re-barreling for a different caliber or replacing a worn original, this Proof Research pre-fit offers an accurate, lightweight, and easy-to-install upgrade.
