POF Minuteman Upper | 5.56 NATO

The Patriot Ordnance Factory Minuteman Complete Upper is a purpose-built AR-15 upper assembly chambered for .223 Rem/5.56x45mm NATO. It is built around a 4150 chrome moly vanadium steel, nitride-treated barrel and uses POF’s E Squared chambering for reliable function. The upper is fitted with a Renegade-style M-LOK handguard, an ambidextrous charging handle, and a three-pronged flash hider, and it ships optic-ready with no sights installed. The design uses a direct impingement gas system and includes multiple integrated quick-detach sling mounts for carry options.

This complete upper brings POF engineering to a ready-to-install AR-15 assembly: materials and finishes are selected for durability, the rail and M-LOK slots support modern accessory layouts, and the E Squared chamber is intended to support reliable function with common 5.56/.223 ammunition. It is a practical choice for precision-minded shooters building a modern sporting rifle configuration or for those assembling a lightweight patrol-style upper where modularity and accessory mounting are priorities.
