5.56mm Nato 16'' East India Upper Receiver

The 5.56mm NATO 16'' East India Upper Receiver from Sons of Liberty Gun Works delivers professional-grade performance for law enforcement, military, and civilian tactical operators who demand reliability in field conditions. This upper receiver assembly serves as the foundation for a complete rifle platform, engineered to handle sustained operations without compromise. Whether building a duty rifle, backup carbine, or precision-tuned training platform, this component meets the exacting standards required by trained shooters and professional end-users.

Constructed with Sons of Liberty's proven East India manufacturing process, this upper receiver features precision-machined receivers and barrels designed for tight tolerances and minimal shift under rapid fire. The 16-inch barrel length provides the optimal balance between velocity retention and controllability—standard for intermediate-range combat carbines and favored by operators who prioritize maneuverability in confined spaces. The 5.56mm NATO chambering ensures compatibility with all standard NATO-spec ammunition and magazines, allowing seamless integration into existing armories and supply chains. Weighing 2.9 pounds, the upper assembly remains lightweight without sacrificing structural integrity or heat dissipation capability during extended shooting cycles.

This upper receiver pairs with any standard AR-15 lower receiver to create a complete rifle system, making it ideal for tactical professionals, competitive shooters, and dedicated enthusiasts building modular platforms. Installation requires only basic armorer knowledge and standard tools; the upper assembly simply slides onto a properly assembled lower receiver and is secured with a takedown pin. Sons of Liberty's reputation for accuracy and durability makes this component suitable for high-round-count training, duty applications, and demanding field use where rifle performance directly impacts mission success.
