This 26-inch stainless barrel features a dedicated 6 GT chamber and a threaded muzzle, giving competitors a stable platform that is ready for brakes or suppressors while maintaining consistent point of impact.
Optimized around the efficient 6 GT cartridge, the barrel’s 1:7.5 twist rate supports modern high-BC projectiles for long-range practice and precision rifle competition. The competition contour balances rigidity and weight, while stainless construction helps manage heat over extended strings of fire.
