Rock River Arms X-1 Operator | .308 Win | 18″ | XBT31751B.V1

The Rock River Arms X-1 Operator is a semi-automatic modern sporting rifle chambered for .308 Winchester/7.62 NATO built with an 18″ fluted stainless steel barrel and a 17″ free-float M-LOK handguard. It ships optic-ready and includes a RRA Operator six-position carbine stock, Hogue pistol grip, two-stage trigger, and one detachable 20-round magazine. For optics, a mid-range variable scope such as the Vortex Crossfire II 2-7×32 pairs well for general precision and range work while staying under typical $1000 cost thresholds.

Applications: precision target shooting at regional matches and mid- to long-range range practice or hunting where a robust .308 platform is appropriate.
