The Patriot Ordnance Factory Minuteman Complete Upper (brand part no. 01652) gives AR-15 builders a 16.5-inch, 5.56x45mm NATO upper built around some of the most refined engineering in the POF-USA lineup. The 4150 nitride-treated steel barrel is fitted with a three-pronged flash hider and cut with an E Squared chamber for reliable feeding and accuracy, running as a semiautomatic direct impingement system. A Strike Eagle ambidextrous charging handle is built for speed and comfort regardless of shooting hand, and the Renegade M-LOK rail gives builders room to mount lights, grips, and other accessories along the full length of the handguard. Four integrated quick-detach sling mounts add flexible carry options, and the whole assembly is machined to MILSPEC upper receiver tolerances. It ships optic-ready with no iron sights installed, built for AR-15 owners who want a genuinely high-end upper without building one from individually sourced parts.
