This assembled upper receiver is designed for compatible AR-15-pattern rifles and pistols. It provides a factory-assembled receiver housing for new builds, replacement projects, or repairs and includes the forward assist and ejection-port-cover components already installed.
Built to Ruger’s standards for rugged reliability, the black forged receiver reduces the number of small components that must be installed separately. Because AR-15 parts can vary between manufacturers, Ruger recommends confirming compatibility and having the receiver installed by a qualified gunsmith.
