Ruger American Gen II 6mm ARC Rifle 20" Barrel - Gray Splatter

Ruger American Gen II 6mm ARC Rifle 20" Barrel - Gray Splatter

Bridge the gap between custom-tier precision and real-world affordability with the Ruger American Rifle Generation II chambered in 6mm ARC (Advanced Rifle Cartridge). Building upon the proven lineage of Ruger's iconic bolt-action platform, the Generation II redesign integrates high-demand performance enhancements tailored for modern long-range hunters, predator specialists, and precision target shooters. Purpose-built around the flat-shooting, high-ballistic-coefficient 6mm ARC cartridge, this rifle weighs in at an agile 6.5 pounds, delivering benchrest accuracy and minimal recoil in a package that maneuvers effortlessly through dense cover or across rugged backcountry terrain.

At its mechanical heart, the American Rifle Gen II utilizes a cold hammer-forged, medium-contour 20-inch barrel featuring deep spiral fluting to shed forward weight, expedite cooling, and preserve extreme harmonic rigidity. The barrel is cut with a fast 1:7.7" twist rate to stabilize heavy match projectiles and threaded in standard 5/8x24, capped with a factory-installed radial port muzzle brake that significantly mitigates muzzle jump. The barreled action is locked into Ruger's patented Power Bedding™ integral bedding block system to guarantee a truly free-floated barrel. Driven by a CNC-machined one-piece stainless steel bolt with a short 70° throw for maximum optic clearance, an oversized 5/16"-24 threaded handle, and a user-tunable Ruger Marksman Adjustable™ trigger breaking crisply between 3 and 5 pounds, every trigger pull is smooth, predictable, and repeatable.

Ergonomics and modularity are central to the Gen II upgrade. The reinforced synthetic stock features a tactile Gray Splatter finish that ensures a non-slip grip in wet or freezing environments without being overly abrasive. Shooters can customize fit out of the box thanks to an adjustable length-of-pull system (modular from 12.0 to 13.75 inches via removable spacers) and an installed low comb riser optimized for magnified riflescopes. Fully shielded in a weather-impervious Gun Metal Gray Cerakote on the barrel, brake, receiver, and bolt handle, and feeding reliably from included 10-round AR-pattern magazines, the Ruger American Rifle Gen II in 6mm ARC represents a benchmark in production rifle engineering.
