Aero Precision Stripped AR-15 M16 Upper Receiver

Nice tight fit. Good as any upper I have used. For the price , can't beat it! Will buy more.

In my opinion Aero Precision uppers are THE best. I have built many AR's using them and the two i just purchased here are no exception. what makes these uppers superior to other brands/manufactures: 1). the machining on these are always flawless, no tooling marks or imperfections (unless you buy a scratch and dent) even when compared to other high end brands, these stand out for the uniformity. which brings me to the next feature, 2). uniformity, every Aero upper i have used was perfectly uniform in manufacturing and went together as well as one could hope for. 3). the finish, the best out there that i have seen. again perfectly uniform, very smooth and exceptionally durable compared to other brands 4) forgings, all of their uppers clearly have one of the major forge markings which means you reasonably can trust that they are what they say they are. 5) price, hands down one of the cheapest available and still better all around than others costing twice as much I have used high end billet uppers and the cheapest $39 specials and everything in between. There is no need to spend $$$ on the fancy billet receivers from a functionality standpoint, and on the other end of the spectrum, you can save $10 and get something of questionable quality, tolerances, and fit and finish that you may even find unusable. so really you only need to ask yourself one question, do I want a forward assist or no forward assist? because either way the answer is Aero Precision!

This upper is absolutely flawless and fits perfectly on the Aero Precision Gen 2 lower.
