Proof Research Prefit Barrel for Tikka T3x – 6mm Creedmoor, 22-Inch

The Proof Research Prefit Barrel is a drop-in carbon fiber barrel designed for Tikka T3x short-action rifles chambered in 6mm Creedmoor. This 22-inch barrel uses Proof's proprietary carbon fiber wrap over a match-grade stainless steel liner, delivering precision accuracy with reduced weight compared to traditional steel barrels. The prefit design allows installation without gunsmithing—headspace is set at the factory for proper bolt lockup and safe operation.

Compatible with all Tikka T3x short-action receivers. Includes threaded muzzle with 5/8x24 TPI threads for brake or suppressor mounting. Barrel contour is optimized for a balance of rigidity and weight savings. Carbon fiber construction provides improved heat dissipation and reduced harmonic vibration during sustained fire. Made in the USA.
