This rifle combines proven AR-15 ergonomics with Ruger's manufacturing precision to create a dependable firearm suitable for hunting, home defense, and tactical applications.

What Makes This Different

The 16.1-inch heavy contour barrel provides enhanced accuracy and heat dissipation compared to standard profile barrels, while the 300 Blackout chambering offers superior performance with suppressed shooting and close-range effectiveness. Hard coat anodized 7075-T6 aluminum forgings deliver military-spec durability that exceeds standard aluminum construction. The flat-top receiver design accommodates any optic system without requiring additional rail modifications.
