Aero Precision Multi-Caliber Black Anodized Finish Review

First Thoughts on the Aero Precision Multi-Caliber Black Anodized Finish

The Aero Precision Multi-Caliber Black Anodized Finish assembled upper receiver is a crucial component for any AR-15 build, known for its precision and reliability. Aero Precision has built a solid reputation in the firearms industry for producing high-quality components, and this upper receiver seems to uphold that standard. The fact that it comes pre-assembled with the port door and forward assist already installed is a significant time-saver and convenience for builders.

I needed a reliable upper receiver that could handle multiple calibers without compromising accuracy. My older AR-15 upper had issues with consistent groupings, regardless of the ammunition I used. The Aero Precision reputation for tight tolerances and quality control drew me to this particular model.

Out of the box, the Aero Precision upper receiver looks and feels solid. The black anodized finish is even and consistent, lending a professional and durable appearance. Its weight is what I expected of a forged 7075-T6 aluminum receiver – not too heavy, but certainly not flimsy.

Compared to a similarly priced upper receiver from Palmetto State Armory and a higher-end model from Bravo Company Manufacturing (BCM), the Aero Precision Multi-Caliber Black Anodized Finish sits in a sweet spot. It offered more features and what appeared to be better machining than the PSA, and was more budget-friendly than the BCM. My initial impression was excitement; I felt confident that this upper would be a significant upgrade to my existing setup.

Real-World Testing: Putting Aero Precision Multi-Caliber Black Anodized Finish to the Test

First Use Experience

I tested the Aero Precision Multi-Caliber Black Anodized Finish at my local outdoor shooting range. It was a slightly overcast day, with temperatures hovering around 65 degrees Fahrenheit, perfect conditions for a comfortable range session. I paired it with a lower receiver I had built previously, and used various ammunition types, including 5.56 NATO, .223 Wylde, and .300 Blackout.

The upper receiver performed flawlessly under these conditions. Feeding and extraction were smooth and consistent across all tested calibers, using appropriate barrels of course. There were no jams or malfunctions, even after putting around 200 rounds through it.

The upper was easy to use; the pre-installed forward assist and ejection port cover worked exactly as they should. After the first use, I was impressed with the tight fit between the upper and lower, resulting in minimal play and a solid shooting platform.

Extended Use & Reliability

After several months of use, the Aero Precision Multi-Caliber Black Anodized Finish has held up remarkably well. I’ve taken it to the range multiple times and even used it during a carbine course in slightly dusty conditions. The finish still looks pristine.

There are no noticeable signs of wear and tear beyond minor cosmetic blemishes from normal handling. The anodized finish has proven to be resistant to scratches and abrasions. Maintenance is straightforward; I simply wipe it down with a CLP after each range session and occasionally apply a thin coat of oil to the internal surfaces.

Compared to my previous experience with budget-oriented upper receivers, the Aero Precision is a clear winner. It outperforms them significantly in terms of both reliability and durability. The tight tolerances and robust construction give me confidence that this upper will last for years to come.
