The BSF SF3IYT0142 AR-15 Semi-Auto 22 ARC 20" 1-7 barrel brings precision-focused engineering to the AR-15 platform. This 20-inch barrel is built around a semi-auto configuration and optimized for the modern 22 ARC cartridge, pairing a 1:7 twist rate with a rigid profile to support high-performance, long-range loads.

This model is ideal for shooters who want to stretch the legs of the 22 ARC for range work, target shooting, or varmint hunting while maintaining the familiar handling of an AR-15. The 20" length and fast twist help stabilize heavier bullets for consistent accuracy, and the barrel’s configuration is well suited to dedicated uppers or custom builds. BSF Barrels is known for attention to detail and accuracy-driven craftsmanship, making this barrel a strong foundation for a precision-oriented AR.
