The Patriot Ordnance Factory Minuteman Complete Upper in .300 Blackout (brand part number 02073) is a fully assembled 13.75-inch pistol-length upper finished in bronze, featuring a pinned Dead Air Keymo muzzle brake, a low-profile gas block, and POF-USA’s M-LOK compatible Renegade rail. It ships with POF’s Mil-Spec enhanced bolt carrier and patented roller cam pin. This is an upper receiver assembly only, with no lower receiver included, so it is not itself a regulated firearm; because the barrel measures under 16 inches, pair it with a pistol-configured or properly registered SBR lower.

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.

Why pistol-length gas on a .300 Blackout upper? A pistol-length gas system is tuned for reliable cycling on this shorter 13.75-inch barrel, where a longer gas system would not have enough barrel length to work properly.

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