When I opened the box I was amazed a t the quality and appearance of this upper. It is super light. Liked so much immediately started looking for another for another build. This has it all and for the price nothing out there compares

Bought the 14.5" and mated it to a Geissele Super-Duty lower. Fit is great, no slop or gap. Shot about 3/4" MOA CTC with 75 gr HPBT. Gassing feels correct, cycled a standard full-auto bolt with a H buffer perfectly. Hand guard is as slim as it gets but still plenty ergonomic, and super light. Would definitely buy again.

I ordered a mlok but received keymod. I was going to a class the next day, so I ran with it. Besides that it runs great fits great. Aero is making great parts. I can’t tell the difference in quality between Aero and BCM anymore.

It clearly states it does not have a BCG or CH. Do not rate it low because you can’t read. The upper itself is awesome and a great value for the price. Machining is on point. This is a better product than the sloppy work done at PSA.

This Aero Precision upper makes the third different manufacturer upper I've tried. Cost wise it sits in the middle out of the three. The upper came packaged well and arrived with no machining blemishes or shipping damage. I have mated the Aero upper with a Anderson lower and the fit is amazing. The Aero upper fits snug and secure to the lower like it came from factory that way. The Aero upper fits my S&W M&P15 lower better than that firearms own upper. Took it out to range today and put 200rds through it with no cycling or FTF issues. Overall a very well manufactured upper receiver. Although it's listed as a complete upper, it doesn't come with BCG or charging handle.

I purchased this complete upper having had several Aero Precision products before. All have been excellent, and this has been no different. It is solid and lightweight, and the fde color matches my rifle perfectly. I would recommend it to anyone.
