The Vltor Modular Upper Receiver (MUR) is a unique AR-15 Flat-Top upper receiver that undergoes a rigorous quality control procedure during manufacture to ensure a precise, strong and consistent product that will serve the shooter for a lifetime. Vltor CNC-Machines the 7075 Aluminum Forging only after it has been fully stress relieved, and then heat- and cryogenically treated. Each upper is finished by hand and all critical dimensions inspected, and finally given a protective Type III, Class 2 Hard Anodized Finish. The MUR is available in 2 variations: With an Integrated Forward Assist/Shell Deflector, and with a Shell Deflector Only. Both models come complete with an ejection port door installed.
This MUR Upper's Modular Side Plate comes equipped with the Shell Deflector Only, it does not have provision for a forward assist.
