Patriot Ordnance Factory Minuteman Complete Upper 5.56x45mm NATO 16.50" Black Nitride Barrel Aluminum Black Anodized Receiver 14.50" M-LOK Handguard Lo Pro DI Gas Block (Mid Length)

The Patriot Ordnance Factory Minuteman Complete Upper 5.56x45mm NATO 16.50" Black Nitride Barrel is a mid-length direct impingement upper receiver assembly engineered for shooters who demand reliability, modularity, and field-proven performance. Built from the ground up for professional and civilian operators, this complete upper addresses the core requirement of any serious rifle platform: a dependable, accuracy-focused upper with minimal maintenance burden. The Minuteman designation reflects POF's commitment to delivering combat-ready components without compromise, making it ideal for duty carbines, training platforms, and precision-focused 5.56 builds.

This complete upper features a 16.50-inch barrel with black nitride finish—a proven surface treatment that provides superior corrosion resistance and reduced friction compared to chrome-lined alternatives, translating to extended service life and easier cleaning between deployments. The aluminum receiver is hard-anodized in black, ensuring durability and consistent aesthetics across modern tactical platforms. The 14.50-inch M-LOK handguard distributes accessories and optics mounting points efficiently while keeping overall length compact for vehicle operations and CQB environments. A Lo Pro direct impingement gas block with mid-length gas tube tuning optimizes dwell time for 5.56x45mm NATO ammunition, reducing bolt velocity variance and supporting reliable function across civilian and military-spec loads without excessive wear on critical components.

Law enforcement tactical teams, military contractors, and civilian shooters building precision-oriented carbines will find immediate value in this upper's plug-and-play design—simply install on any mil-spec lower receiver and run. The 5.04-pound weight keeps the complete upper balanced for extended engagement and maneuvering without fatigue, critical for door-breach operations or long-range transitions. M-LOK compatibility ensures seamless integration with modern slings, grips, light mounts, and covers, while the mid-length gas system excels in suppressed and unsuppressed configurations. This upper performs equally well with standard-pressure and commercial-load ammunition, making it adaptable across training cycles, qualification ranges, and operational deployments.
