A short-barreled upper receiver assembly for the AR-15 platform, designed for pistol-length firearms and incorporating an integrated carrying handle/rear sight assembly, offers a compact and maneuverable firearm configuration. This specific configuration typically features a barrel length of less than 16 inches and is legally classified as a pistol under United States federal law, contingent upon specific build requirements.
The integrated carry handle provides a convenient method for transporting the firearm and a readily available sighting system. This combination of features appeals to those seeking a compact platform for home defense or competitive shooting disciplines where maneuverability is paramount. Historically, the carry handle design harkens back to the original M16 rifle, giving these modern pistol variants a classic aesthetic. Its simplicity contributes to the overall lightweight nature of the firearm, making it easier to handle and control.
