Patriot Ordnance Factory Minuteman Complete Upper 5.56x45mm NATO 10.5" 9" M-LOK Handguard AR-15

The Patriot Ordnance Factory Minuteman Complete Upper is a purpose-built AR-15 upper receiver assembly chambered in 5.56x45mm NATO and built around a compact 10.50" barrel. Made in the USA by POF, the Minuteman upper pairs a 4150 Chrome Moly Vanadium Steel barrel with a Black Nitride finish for long-term durability and corrosion resistance in a short, fast-handling configuration.

The 10.50" barrel uses POF's E Squared chamber geometry, optimized for reliable feeding and extraction across a broad range of 5.56 NATO and .223 Remington ammunition. A direct impingement gas system routes through a low-profile Lo Pro DI gas block positioned at mid length, delivering smooth cycling and reduced felt recoil compared to shorter carbine-length systems.

The upper receiver is machined from aluminum and finished in Black Hard Coat Anodized, providing a tough, low-reflectivity surface that holds up to hard field use. The integrated 9" M-LOK handguard is finished in matching Black Anodized and offers a slim, lightweight platform for mounting lights, lasers, grips, and other accessories along its M-LOK compatible slots and a continuous Picatinny rail up top. The upper ships optic ready with no iron sights installed, giving the end user full freedom to configure their preferred optic or red dot.

Drop the Minuteman upper onto any mil-spec AR-15 lower receiver to complete a compact, fast-handling 5.56 NATO rifle. This is a new, factory-fresh POF upper, perfect for builders looking to assemble a short-barrel AR without compromising on quality components.
