Ruger AR-15 Assembled Upper Receiver 91003

The Ruger AR Upper Receiver (model 91003) is the genuine factory AR-15 pattern upper receiver from Ruger, supplied in the assembled configuration with the factory small parts already installed. This component is designed to mate with any standard AR-15 lower receiver, making it suitable for completing a custom build or replacing an existing upper on an AR-platform rifle.

As an assembled upper (as opposed to a stripped upper), the 91003 ships with the factory small parts needed to accept a barrel and the remaining upper internals during a build. Retailer-listed weight is approximately 0.47 lb for the receiver body. Manufactured by Ruger, the 91003 is a standard AR-15 component.
