Rise Armament RA-22ARC 18″ Upper Receiver Assembly – 22 ARC, Aluminum Handguard

The Rise Armament RA-22ARC Upper Receiver Assembly delivers a high-performance platform chambered in the hard-hitting 22 ARC cartridge, purpose-built for precision shooting, hunting, and competitive applications. Featuring an 18-inch 416R stainless steel barrel that is button-rifled, air-gauged, and tested for consistency, then threaded for suppressor or muzzle device compatibility, this upper is engineered for accuracy right out of the box.

The free-floating skeletonized aluminum handguard provides a rigid, lightweight foundation with a continuous 12 o’clock Picatinny rail for optics and accessories, M-LOK attachment slots along the sides and bottom, four threaded steel sling swivel QD inserts for versatile sling configurations, a snag-free front end, and a patent-pending attachment lock system designed to maintain your zero under repeated use.

The included Rise Armament ambidextrous charging handle supports both right- and left-handed shooters, with an ergonomic design optimized for use with magnified optics and tactical gloves. The premium bolt carrier group is built around a 9310 steel bolt that is individually magnetic particle inspected (MPI) tested, paired with a staked gas key and a durable black nitride finish for long-lasting reliability in demanding conditions. The forged billet aluminum receiver provides a solid, precisely machined foundation that brings the entire assembly together with tight tolerances.
