Designed for multiple government agency programs and various top-level law enforcement groups, the Assurance Carbine from Rock River Arms is a mission-specific rifle.

The RRA Assurance Carbine takes a proven design and modifies the functionality to meet today’s fast-paced operations. Like many of RRA’s rifles, the Assurance Carbine is built around precision made and assembled upper and lower receiver assemblies. Chambered in 5.56mm NATO, the Assurance is equipped with a premium 16-inch chrome moly barrel to deliver 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.

Rock River Arms also added a redesigned free-float quad-rail handguard to the Assurance Carbine—a feature many law enforcement and government agencies requested and influenced the design of this rifle. 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.

The Assurance Carbine includes a CAR-length gas system, gas block with receiver height rail and sling mount, Hogue overmolded pistol grip, RRA 6-position buttstock with sling mound, one 30-round poly magazine, hard case, and a lifetime warranty.
