Rock River Arms LAR15M CAR A4 | .350 Legend | 16″

The Rock River Arms LAR15M CAR A4 is a modern sporting rifle chambered in .350 Legend with a 16″ barrel and a 13″ lightweight M-LOK free-float handguard. It ships with an RRA overmolded A2 grip, a two-stage trigger, one 10-round detachable magazine and a protective Rock River case. For optics under $1,000 that pair well with this platform consider the Vortex Viper PST Gen II 1-6×24 or the Vortex Strike Eagle 1-6×24 for fast target acquisition and durable, repeatable performance.

Intended uses include short- to moderate-range deer hunting and precision-focused range practice where .350 Legend delivers effective terminal performance without needing a pistol-caliber-carbine setup. The rifle’s configuration suits shooters who want an AR-style platform optimized for straight-wall cartridge performance.
