Aero Precision AR 308 Ejection Port Cover Kit Review

Let’s Dive into Aero Precision AR 308 Ejection Port Cover Kit

The Aero Precision AR 308 Ejection Port Cover Kit is a seemingly small, but absolutely crucial component for any AR-308 build. Aero Precision is known for its quality components, and this kit, designed specifically for their M5 (.308) upper receivers, promises to uphold that reputation. I’ve built more AR-platform rifles than I can count, and the ejection port cover is always one of those last-minute items you don’t want to overlook.

My current AR-308 build was nearing completion, and I needed a reliable ejection port cover. I wanted something that would not only function flawlessly but also match the overall aesthetic of the rifle. After considering a few cheaper options, I opted for the Aero Precision kit because I trusted their quality and precise fitment.

The kit arrived in a simple, no-frills package. Upon opening it, I immediately noticed the clean, black finish and the solid feel of the components. Compared to some of the cheaper, stamped-steel covers I’ve used in the past, this one felt significantly more robust. I considered a similar kit from DPMS, but the Aero Precision kit had better user reviews citing fit and finish.

My first impression was positive. The kit appeared well-made, and I was eager to install it and get the build finished. I was hoping it would live up to Aero Precision’s name, and prevent any malfunctions due to debris.

Real-World Testing: Putting Aero Precision AR 308 Ejection Port Cover Kit to the Test

First Use Experience

The initial installation took place in my workshop, during the final stages of the AR-308 build. Installation was straightforward, mimicking any standard AR-pattern ejection port cover, however the fitment into the Aero Precision M5 upper receiver was exact. The pin slid in smoothly, and the spring provided adequate tension to keep the cover closed.

I tested the rifle at an outdoor range, focusing on cycling different .308 ammunition types. The ejection port cover functioned flawlessly, snapping open during firing and closing securely afterward, even after several magazines.

Extended Use & Reliability

After several range trips and around 500 rounds fired, the Aero Precision AR 308 Ejection Port Cover Kit continues to perform flawlessly. There are no visible signs of wear or tear, and the finish remains intact. Maintenance is minimal, involving only an occasional wipe-down with a lightly oiled cloth.

Compared to some other ejection port covers I’ve used, this one has significantly outperformed them in terms of durability and consistent function. Others tended to bend or lose their spring tension after extended use, which this one avoids. The solid construction of the Aero Precision kit makes it a clear winner.
