The Patriot Ordnance Factory P415 Complete Upper 5.56x45mm NATO 10.50″ Black Nitride Barrel Aluminum Black Anodized Receiver 9″ M-LO Made a Bold First Impression
In the world of AR-15 uppers, the Patriot Ordnance Factory (POF-USA) P415 Complete Upper 5.56x45mm NATO 10.50″ Black Nitride Barrel Aluminum Black Anodized Receiver 9″ M-LO enters the arena as a contender promising unwavering reliability and enhanced ergonomics. Boasting POF-USA’s renowned E2 Extraction Technology and a slimmed-down M-LOK handguard, this upper aims to be the pinnacle of modern sporting rifles. My journey to acquire this upper stemmed from a need for a compact and dependable platform for close-quarters training and vehicle deployment scenarios.
For years, I’ve been piecing together AR builds, always searching for that perfect balance of size, weight, and unyielding performance. My existing 11.5″ upper, while reliable, felt a bit bulky, and I was intrigued by POF-USA’s claims of improved ergonomics and enhanced extraction. This upper, with its 10.5″ barrel and focus on reducing overall dimensions, immediately piqued my interest.
Unboxing the P415 upper was a tactile experience in quality. The black anodized finish of the receiver was flawless, exuding a sense of durability and attention to detail. The handguard felt remarkably slim and comfortable in hand, a clear departure from the bulky quad rails of yesteryear.
I was torn between this and two other popular SBR uppers: the Daniel Defense MK18 and the Bravo Company Manufacturing (BCM) MK2. While the MK18 is a legend, its price point is significantly higher, and the BCM, while excellent, didn’t offer the innovative E2 Extraction Technology that POF-USA is known for. I ultimately chose the P415 for its unique combination of features and its reputation for rugged reliability.
My initial impression was one of excitement tempered with cautious optimism. The P415 certainly looked the part, but the true test would be how it performed under pressure. It had the feel of a weapon system that was built to be used hard, a true testament to the Patriot Ordnance Factory philosophy.
Real-World Testing: Putting Patriot Ordnance Factory P415 Complete Upper 5.56x45mm NATO 10.50″ Black Nitride Barrel Aluminum Black Anodized Receiver 9″ M-LO to the Test
First Use Experience
My first range trip with the P415 upper was at an outdoor range known for its varied conditions. I wanted to push the upper in different environments. The weather was typical for a late summer day – sunny, humid, and a light breeze carrying dust across the shooting line.
I ran several hundred rounds of mixed ammunition through the upper, ranging from standard 55-grain FMJ to heavier 77-grain OTM rounds. Even with a suppressor attached for a portion of the session, the rifle cycled smoothly and reliably. The slim handguard made for comfortable handling, even after extended periods of shooting. There was virtually no felt difference from my previous non-ambi charging handle.
The P415 performed flawlessly, with no malfunctions or hiccups of any kind. The only minor surprise was the amount of muzzle flash, which is to be expected with a short-barreled rifle.
Extended Use & Reliability
After several months of consistent use, including multiple range trips and a carbine course, the P415 has proven to be incredibly reliable. The black nitride barrel shows no signs of wear, and the anodized finish on the receiver has held up well to bumps and scrapes. Cleaning is straightforward.
Maintenance involves the standard AR-15 cleaning regimen, with particular attention paid to the gas system. I clean and lubricate the bolt carrier group after each range session. This ensures smooth operation and longevity.
Compared to my previous upper, the P415 offers a noticeable improvement in reliability, especially when running suppressed. The E2 Extraction Technology seems to make a difference in ensuring consistent extraction, even with hotter loads. The improved ergonomics of the handguard also make it more comfortable to shoot for extended periods.

Performance & Functionality
The P415 upper excels in its primary role: delivering reliable and accurate performance in a compact package.

The enhanced extraction, due to POF-USA’s E2 technology, is a notable strength, particularly when running suppressed or with less-than-ideal ammunition.
The only area that could potentially be improved is the muzzle flash, which is inherent to short-barreled rifles. This is easily mitigated with the use of a good flash hider or suppressor. Overall, the P415 meets and exceeds expectations for a high-quality, short-barreled AR-15 upper.
