First of all: I really like Aero Precision products. I have build 3 COP rifles, and I now have 4 of their new M4E1 with the enhanced handguard and they are an awesome design.
<Rant>
Now the rant: Aero customer service and QC on the M5E1 sucks... Like bad... How fucking hard is it to send the right product the first time to a paying customer? And then, how hard is it to admit you made a mistake, and ship the replacement part quickly and expedite the shipping? Well I guess, when you are aero, it is TOO HARD!
First: ordered everything to build a M5E1 enhanced upper from aero (800$), receive the wrong upper (I bought the lower and lower parts locally)... The M5E1 particularity is to have an integrated handguard mount for their enhanced handguard, the one I received was the standard M5.... Pretty obvious difference. It took me 3 days, 3 emails, 4 phone call and a picture of the part, to make them admit they shipped the wrong one. So, what is their answer? Ship us back the upper, and we will ship the other one back! really, 3 weeks later I finally get my part, and with a lot of excitement, I try to put my upper together, and realize that:
1 - It is more than a tight fit between their upper and lower, and it will need some serious adjustment to perfectly work.
2 - the quick detach barrel nut advertised on their website was not the one I received
3- Worse: the enhanced handguard they send me will not fit the upper....
Back to calling them, get the cold shoulder treatment, and having to spend hours on the phone / email......

BTW: This is what it should look like when it's done
