Reviews & Ratings for Aero Precision M5E1 20in .308 Barrel Complete Upper Receiver with Flash Hider — 25 reviews — Page 1

Good deal if you can get this bundle on sale. Very little wiggle between its matching .308 Aero M5 lower. Pretty :)

Quality upper for price. Can’t wait to finish this build and hit the range.

The fit and finish are amazing and I love the precision handguard mounting system

The Aero Precision M5E1 20” .308 Barrel Complete Upper Receiver is an outstanding product that excels in accuracy, reliability, and value. Right out of the box, it’s clear that Aero Precision has crafted this upper with precision and attention to detail.

The accuracy is one of its key strengths. Whether you’re at the range or shooting long-range, the 20” barrel delivers excellent precision, producing tight groups and consistent results. It’s a great choice for those looking to get the most out of their .308 build.

Reliability is another area where this upper stands out. I’ve had zero issues with feeding, cycling, or ejection, making it a dependable option for a wide range of ammunition—from high-quality match rounds to more budget-friendly bulk ammo.

Price-wise, this upper offers great value for the quality you get. The combination of a top-tier barrel, precision machining, and solid construction makes it a competitive option at its price point.

Looking forward to putting this thing to the real test at a few gas gun PRS matches. If it performs as well in competition as it has at the range, it will definitely prove to be a winner.

In conclusion, the Aero Precision M5E1 20” .308 Barrel Complete Upper Receiver is a fantastic choice for anyone looking for a reliable, accurate, and reasonably priced .308 upper. Whether you’re building your first AR or upgrading your setup, this upper won’t disappoint.

Was able to select an Aeroprecision upper receiver when their own web site’s inventory was ‘0’. Delivered on time with minimal hassle. Cane with the preferred M-Lock hand guard, too!

Good quality, excellent accuracy, reliable function! Always a budget favorite! This will shoot better than allot of big name brands going for 2-3x more!

I'm building a nice AR-10 with multiple uppers and this fits right in my plans

Took almost 2 weeks to arrive as described. Very happy with this upper.

Its fit is nice. Service was good and delivery time was decent. Price was the best that I could find. I think this was the first time I bought from them and shortly after receiving my upper I ordered other parts that I needed for the build. Probably going to order my scope from them also. I would recommend them.

Fits as it should on my aero lower, finish appears to be good but haven’t shot it yet, still in the building process.
