Patriot Ordnance Factory Minuteman Complete Upper 5.56x45mm NATO 10.50" Black Nitride Barrel Aluminum Black Anodized Receiver 9" M-LOK Handguard Lo Pro DI Gas Block (Mid Length)

The Patriot Ordnance Factory Minuteman Complete Upper in 5.56x45mm NATO is a ready-to-run upper receiver assembly built for shooters who want a compact, efficient platform without compromise. The 10.5" black nitride barrel delivers the velocity and handling balance that makes short-barreled rifles ideal for home defense, tactical training, and close-quarters work. Pair it with a lower receiver and you've got a complete rifle—or build it into an existing platform for quick configuration changes.

This is purpose-built AR engineering: the mid-length gas system keeps the bolt carrier cycle smooth and manageable in a short package, while the lo-pro gas block sits low and tight so it won't interfere with your preferred mounting setup. The 9" M-LOK handguard gives you genuine modularity—attach lights, grips, and accessories where they make sense for your shooting style, not where the manufacturer predetermined.

The aluminum receiver is hard-coat black anodized for durability and looks, and the black nitride barrel finish resists corrosion without fuss. Whether you're running suppressed, unsuppressed, or experimenting with both, this upper handles the job. It's the kind of no-nonsense component that POF customers have trusted for years—no marketing fluff, just solid metallurgy and proven gas tube engineering.

Frequently Asked Questions

What lower receiver does this upper fit?

This is a standard AR-15 upper receiver and will fit any mil-spec AR-15 lower. Patriot Ordnance Factory manufactures the upper; you'll need to source a lower separately or use one you already own.

Is this upper suitable for short-range defensive or hunting use?

Yes. The 10.5" barrel with mid-length gas system is designed for close to intermediate ranges and will cycle reliably in that role. Performance beyond 200 yards will drop off compared to longer barrels, which is typical for short-barreled rifles in this caliber.

Can I mount a suppressor on this barrel?

The barrel is 5.56x45mm NATO and has a black nitride finish. You'll need to verify with your barrel or contact POF directly to confirm if it's threaded and what the thread pitch is, as that information is not provided here.

What's included in this upper assembly?

You receive the complete upper receiver with barrel, gas block, handguard, and receiver. You will need to source a lower receiver, buffer tube, stock, and trigger group separately to complete a rifle.
