The Patriot Ordnance Factory Minuteman Complete Upper in 5.56x45mm NATO (brand part number 01815) is a fully assembled 16.5-inch upper built around a 4150 nitride-treated steel barrel and a three-pronged flash hider, finished in Patriot Brown over a 14.5-inch M-LOK handguard. POF’s ambidextrous Strike Eagle charging handle is built in for speed and comfort, and the low-profile direct impingement gas block keeps the mid-length gas system running clean. This is one of the most feature-rich complete uppers in the Minuteman line, built for shooters who want a proven, hard-use AR-15 upper without cutting corners.
