With its .224 caliber bore and 1:8 twist rate, this barrel is optimized for modern, heavy .22-caliber projectiles that stay stable at distance. The Sendero contour and carbon fiber construction help manage heat and maintain accuracy over extended strings of fire, making it a strong choice for range work, practical field shooting, or a lightweight hunting rig.
