Description

Build a serious short-barrel AR-15 around the Patriot Ordnance Factory Minuteman 10.5″ complete upper — POF-USA’s MILSPEC pistol/SBR upper, fully assembled and ready to drop onto any standard AR-15 lower receiver.

What’s in the box:

• 10.50″ 4150 chromoly steel barrel with QPQ black nitride finish for corrosion resistance and extended barrel life
• E-Squared chamber — POF’s hybrid 5.56x45mm NATO / .223 Wylde chamber, safely handles full-pressure 5.56 NATO ammunition while delivering .223 Wylde-class accuracy
• Mid-length direct impingement gas system with low-profile gas block — gas port positioned between carbine and rifle length for noticeably smoother recoil impulse and reduced bolt velocity on a 10.5″ barrel
• 9″ Renegade M-LOK handguard in Patriot Brown — full-length over the gas system with M-LOK accessory slots, anti-rotation tabs, and four integrated QD sling mount points
• Three-prong flash hider — POF’s signature muzzle device, dramatically reduces visible muzzle flash
• Strike Eagle ambidextrous charging handle — extended ambi latch, built for fast right- or left-hand manipulation
• Patriot Brown anodized aluminum upper receiver — POF’s signature FDE-toned finish

Compatibility & legal notice:

This is a short-barrel upper assembly (10.5″ barrel). Federal law dictates how it can be legally assembled:

• Pistol build: Pair with an AR-15 pistol lower (no stock; pistol brace permitted). Legal in most states.
• Short-Barreled Rifle (SBR): Pair with a lower receiver that has been registered as an SBR via ATF Form 1 or Form 4. Legal with the required NFA paperwork.
• Do not install on a standard rifle lower with a shoulder stock unless that lower is already SBR-registered. Mounting a short-barrel upper on an unregistered rifle lower creates an unregistered Short-Barreled Rifle, which is a federal felony under the National Firearms Act.

State-level restrictions on short-barrel uppers, pistol braces, and SBRs vary widely. The buyer is responsible for verifying legality in their jurisdiction before assembly. Gnome Arms ships only to FFL dealers in states where the configuration is lawful.

If you want a short, fast, smooth-shooting AR-15 upper from one of the most respected names in the industry, this is the assembly to build around.
