Which AR15 lower would you choose and why?
Aero Precision (gen 2)
or
Anderson Arms

I wanted to convert my carry handle upper to a rail with my fantasy football winnings, but lost so I won't. But anyways, I was looking at those 2 for uppers.
Digging the around online I found out that Aero supposedly has either sold unfinished forgings or flat out produced receivers as a subcontractor with some other outfits name stamped on the product for years. Based on that I was going to go with Aero.

Aero. Can't stand the Anderson logo.

The Aero should be a better fit. And the Anderson logo is ugly.

I'd go with Aero just on principle. Do some searches on google "Anderson Manufacturing Owner AR15.com" there are several threads where the owner and workers have been really shady in their business dealings.

I have several Aero Precision lowers (5.56 and 308)... they're good stuff

I prefer Aero Precision over Andersen also. I've got several of their stripped uppers and lower ready to be built out.

Aero Precision without a doubt. They and Mega Arms are Aerospace companies that have the experience with tight machining tolerances.

I have both, no problem with the Anderson's but I really prefer the Aero line. I have ar15's and lr10 in Aero and thursday I'm picking up two more uppers and lowers. I also have colt, spikes, PSA and diamondback. I'll buy Aero before any of these.
