The Patriot Ordnance Factory Minuteman Complete Upper in 5.56x45mm NATO (brand part number 01817) is a fully assembled 10.5-inch upper built around a 4150 nitride-treated steel barrel and a three-pronged flash hider, finished in Patriot Brown over a 9-inch M-LOK handguard, sized for a short, fast-handling AR pistol or SBR-configured build. 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-tuned gas system running clean even at this compact barrel length. This is an upper receiver assembly only, with no lower receiver included, so it is not itself a regulated firearm.

Frequently Asked Questions

Is this bare upper itself an NFA-regulated item? No. It is an upper receiver assembly with no lower receiver included, so it is not a regulated firearm on its own. Installing it on a shouldered, rifle-configured lower without a registered short-barreled rifle would require ATF Form 1 approval first.

Does this upper come with a bolt carrier group? Yes, POF Minuteman uppers include POF-USA’s Mil-Spec enhanced bolt carrier and patented roller cam pin.

Does this upper include sights? No, it ships optic ready with no iron sights, so you can mount your preferred red dot or optic directly.
