The BSF SF3IYT0238 Bolt-Action 7mm/284 20" 1-8 barrel brings a modern, carbon fiber–sleeved design to serious rifle builders who want a compact, accurate setup. Built around a stainless steel, button-rifled core with a carbon fiber exterior and threaded muzzle, this 20-inch barrel is engineered to balance stiffness, heat management, and weight savings for bolt-action platforms chambered in 7mm Blaser Magnum.

This configuration keeps overall rifle length manageable while still offering strong velocity potential from the 7mm bore, and the 1:8 twist rate is tailored for stabilizing long, high-BC projectiles. The threaded 5/8"x24 muzzle makes it easy to add a brake or suppressor, and the carbon fiber finish gives the barrel a distinctive, modern look. Ideal for precision-oriented hunting or extended range sessions, this barrel reflects BSF Barrels’ focus on accuracy-driven design and careful craftsmanship.
