Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 Review

The Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 Made a Bold First Impression

As a seasoned outdoor and tactical gear specialist, I’ve witnessed countless AR-15 components come and go. The Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 immediately caught my eye with its promise of handling larger caliber rounds, something I’ve been exploring for hog hunting applications. This upper receiver isn’t just another part; it’s a specialized component designed for builds pushing the boundaries of the AR-15 platform.

I’ve been wanting to build a dedicated hog hunting AR chambered in .450 Bushmaster for some time, but standard AR uppers simply wouldn’t do. The ejection port needed to be significantly larger to reliably cycle those hefty cartridges. I considered other options, like a custom-machined upper, but the cost and lead time were prohibitive. When I saw the Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15, I knew I had to give it a shot.

The upper arrived well-packaged, showcasing the classic Aero Precision attention to detail. Lifting it from the box, the first thing I noticed was the substantial feel of the 7075-T6 aluminum. The black anodized finish was flawless and even, promising excellent corrosion resistance. The enlarged ejection port was immediately apparent, a clear indication of the beefier calibers it was intended to handle. I also appreciated the included forward assist and port door, saving me the hassle of sourcing those separately.

Compared to a standard Aero Precision M4E1 upper I had on hand, the XL version felt only slightly heavier. However, the difference in ejection port size was dramatic. I briefly considered a side-charging upper from another manufacturer, but I preferred the standard AR manual of arms and the sleek aesthetics of the Aero Precision design. My initial impression was one of cautious optimism; this upper appeared well-made and specifically designed for my needs. I was eager to see how it would perform.

Real-World Testing: Putting Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 to the Test

First Use Experience

My first outing with the Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 was at my local shooting range, nestled in the Texas Hill Country. I had mated it to an Aero Precision M4E1 lower and installed a .450 Bushmaster barrel. I brought along a variety of .450 Bushmaster ammunition, from 250-grain to 300-grain projectiles. The Texas sun beat down, and a fine layer of dust coated everything, typical of a dry summer day.

Initially, I experienced a few failures to eject, which I attributed to the break-in period of the new barrel and bolt. After about 20 rounds, the cycling smoothed out significantly. The enlarged ejection port did its job flawlessly, ejecting the spent .450 Bushmaster casings without any jams or hiccups. The Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 proved its worth. I was impressed with the consistent performance, even under dusty conditions.

After several months and hundreds of rounds downrange, the Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 has proven to be incredibly reliable. I’ve taken it on multiple hog hunts in dense brush and muddy terrain. I have experienced no malfunctions directly attributable to the upper receiver itself. The anodized finish has held up remarkably well, showing minimal signs of wear despite being subjected to harsh conditions.

Maintaining the upper is straightforward; a simple wipe-down with a CLP-soaked cloth after each range session is sufficient. Occasionally, I’ll disassemble it for a more thorough cleaning. Compared to some cheaper upper receivers I’ve used in the past, the Aero Precision XL Assembled Upper Receiver 7075-T6 Aluminum Black Anodized Receiver for AR-15 exhibits superior fit and finish. This results in a smoother cycling action and improved overall reliability.
