Rock River Arms introduced its new Assurance Carbine, an AR-pattern rifle originally designed for multiple government agency programs and various law enforcement groups.

The RRA Assurance Carbine takes a proven design and modifies the functionality to meet the needs of the consumer. It is built around precision-made-and-assembled upper and lower receiver assemblies. Chambered in 5.56 NATO, the Assurance is equipped with a premium 16-inch chrome moly barrel to promise outstanding accuracy and extended barrel life in an easy-to-clean platform. Rock River Arms equipped the Assurance with its popular 2-stage trigger to enhance shooter control and increase accuracy potential.

The company also added a redesigned, free-float, quad-rail handguard to the Assurance Carbine—a feature many law enforcement and government agencies requested, among other key components of this rifle’s design. The handguard has full-length Picatinny rails at the 12-, 3- and 9-o’clock positions and a nine-slot rail along the bottom. The new quad rail is constructed of 6061-T6 anodized aluminum, providing users with a functional, compact, lightweight and ergonomic design built for reliable duty.
