The BSF SF3IYT0049 AR-15 Semi-Auto 6ARC 16" 1-7.5 barrel is a precision-focused upgrade for shooters who want a lightweight, rigid option for their AR-15 platform. Built around a 16 inch barrel chambered in 6mm ARC with a 1:7.5 twist rate, it is designed to stabilize modern high-BC projectiles while maintaining consistent accuracy. The exterior shows a distinctive carbon-fiber–sleeved profile with vented ports and a threaded muzzle, pairing reduced weight with excellent heat management.

This configuration is well suited for extended range sessions, target shooting, and hunting applications where flatter trajectories and reliable performance are important. The 6mm ARC chambering offers efficient ballistics from an AR-15, while the semi-auto platform compatibility makes it easy to integrate into existing builds. Backed by BSF Barrels’ reputation for innovative barrel construction and attention to detail, this model is built for shooters who prioritize consistency and quality.
