This specific configuration refers to a short-barreled rifle upper receiver assembly manufactured by Daniel Defense. It combines the company’s renowned quality and reliability with features desirable for close-quarters combat and maneuverability. The 14.5-inch barrel length provides a balance between compactness and ballistic performance. The upper receiver typically includes a government profile barrel, a low-profile gas block, and a pinned and welded muzzle device to meet legal requirements for non-NFA firearms.
The combination of a reputable manufacturer, a compact design, and adequate ballistic performance makes this type of upper receiver popular among military, law enforcement, and civilian shooters. The shorter barrel allows for easier handling in confined spaces while retaining acceptable accuracy and terminal ballistics. This specific build has seen significant use in modern conflicts, contributing to its reputation for reliability under demanding conditions.
