Ruger American Gen II | 6mm ARC | 20″ | 10rd | 46910

The Ruger American Rifle Gen II in 6mm ARC is a full-size, bolt-action sporting rifle built for optic-focused shooting. This Gen II example features a 20-inch spiral-fluted, threaded barrel, an adjustable gray-splatter synthetic stock with removable comb spacer, and a one-piece Picatinny scope base. It ships with a single 10‑round detachable AR‑style magazine and factory-installed radial port muzzle brake. For an optic under $1,000 that pairs well with this platform, consider the Vortex Viper HS-T 4-16×44 for a balance of magnification, glass clarity, and reticle versatility.

Common applications: medium-range precision target work and hunting where the 6mm ARC’s ballistics are desired.

The medium-contour spiral fluted barrel helps with balance while retaining rigidity, and the factory-installed radial muzzle brake reduces felt recoil when shooting higher-performance cartridges.

Its combination of user-adjustable ergonomics and an AR-style detachable magazine make it a versatile choice for shooters who value straightforward, no-nonsense performance.
