Del-Ton AR-15 16" Pre-Ban M4 Flat Top Barrel Assembly 16" Barrel Black

The Del-Ton AR-15 16" Pre-Ban M4 Flat Top Barrel Assembly represents a reliable, purpose-built upper receiver component for shooters who demand proven performance in carbine-length platform configurations. This 16-inch barrel assembly is engineered for law enforcement, military, and civilian tactical applications where a balanced combination of velocity, maneuverability, and accuracy matters. Pre-ban specifications ensure compliance with legacy firearms regulations, making this assembly a practical choice for those building or updating AR-15 platforms to meet specific legal requirements or operational preferences.

This barrel assembly features a flat-top receiver design, which eliminates the carrying handle mount and provides a clean, modular platform for mounting optics, reflex sights, or backup iron sights via standard Picatinny rails. The 16-inch barrel length delivers optimal performance for intermediate cartridges while maintaining the compact profile essential for vehicle operations, close-quarters scenarios, and tactical environments where barrel length directly impacts handling speed and transitional accuracy. Del-Ton's manufacturing standards ensure consistent chamber dimensions and bore quality, critical factors for shot grouping and long-term reliability in duty or training roles.

This barrel assembly is ideal for shooters constructing mid-length gas system carbines, upgrading existing platforms, or maintaining inventory of compatible upper components for modular builds. Installation requires basic armorer knowledge and standard AR-15 upper receiver tools; the assembly pairs with any mil-spec lower receiver or complete lower group. The flat-top receiver design ensures zero shift consistency across optic changes, a critical requirement for firearms used in law enforcement training, precision marksmanship, and dynamic tactical courses where equipment transitions occur frequently and reliability cannot be compromised.
