Vktr Industries V40273410001RP VK-1 Complete Upper 16" for AR-15

The Vktr Industries V40273410001RP VK-1 Complete Upper 16" for AR-15 is a drop-in upper receiver assembly designed for shooters who demand precision, reliability, and modularity in a compact configuration. Built to mil-spec standards, this complete upper is ideal for law enforcement patrol rifles, home defense builds, and tactical operators seeking a proven platform that simplifies assembly while maintaining full functionality. The 16-inch barrel length strikes the balance between velocity, handling, and compliance that makes it a versatile choice for both duty and civilian applications.

Built on VKTR Industries' reputation for precision manufacturing, the VK-1 upper combines a rigidly toleranced receiver with a properly headspaced barrel to ensure consistent accuracy and reliability across extended firing strings. The 16-inch configuration delivers optimal muzzle velocity while maintaining the ergonomic advantages of a shorter platform—critical for vehicle-mounted operations and CQB scenarios where maneuverability matters. At 7.23 pounds, the complete upper balances mass for reduced recoil impulse without sacrificing the structural integrity required for duty-cycle demands, making it suitable for both 5.56 NATO and .223 Remington ammunition.

Law enforcement agencies and tactical teams benefit from the VK-1's plug-and-play design—simply mate it to any mil-spec lower receiver and you're ready for duty or training. The complete upper arrives ready to function, eliminating the need for barrel installation, gas tube timing, or receiver honing that creates failure points in field assembly. This configuration is fully compatible with standard AR-15 lower receivers and accepts all mil-spec furniture, optics mounts, and accessories, making it an economical upgrade path for existing platforms or new builds requiring immediate deployment readiness.
