Patriot Ordnance Factory Minuteman Complete Upper 5.56x45mm NATO 16.50" Black Nitride Barrel Aluminum Patriot Brown 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 battle-proven upper receiver assembly designed for shooters who demand reliability without compromise. Built for tactical professionals, law enforcement, and serious sportsmen, this complete upper eliminates the guesswork of component selection and pairing. Patriot Ordnance Factory's reputation in the military contracting space translates directly to civilian-grade performance: every component is engineered to function flawlessly under sustained fire and adverse conditions.

The 16.50-inch barrel with black nitride finish provides the optimal balance between velocity retention and handling characteristics for mid-length gas systems—a proven configuration for 5.56 NATO. The mid-length direct impingement gas block reduces felt recoil and extends component life compared to carbine-length systems, a critical advantage in high-round-count training or sustained engagement scenarios. The 14.50-inch M-LOK handguard offers genuine modularity without excess weight; M-LOK slots accept tactical accessories throughout the rail system, and the low-profile design maintains natural ergonomics while keeping overall assembly weight at just 5.05 lbs. The Patriot Brown aluminum receiver contrasts both aesthetically and functionally, providing superior corrosion resistance in harsh environments. This upper ships as a complete, ready-to-fire assembly—simply marry it to your lower receiver and you're mission-ready.

This upper benefits shooters building or upgrading AR-15 platforms where component quality directly correlates to reliability. Law enforcement agencies and military end-users standardize on mid-length gas systems for their reduced wear signature and softer impulse—factors that matter in duty applications where uptime is non-negotiable. Installation requires only a properly staked gas tube and standard AR-15 takedown pins; no special tools or gunsmithing skills needed. The complete upper is compatible with any mil-spec AR-15 lower receiver, making it a versatile foundation for 5.56 NATO builds across tactical, competitive, and training disciplines.
