I'm a dealer for both. Aero precisions anodized parts look clean and uniform. Their anodized receivers and rails are nice and that's where their value is at for me.Well let's just kindly agree to disagree on this one and still be civil. Ok have used a lot of parts from different manufacturers/ vendors. I mainly use BCM, Daniel Defense, Wilson Combat, PWS and a few other decent places. Now I have used I can't tell how many Aero parts and friends that have used them without issue. That is over the last 6 to 8 years. All parts from AP we're perfect in fit and finish and I haven't heard of a failure from those I helped since their builds. So I have faith in the AP brand. Unfortunately they don't offer a $99.00 Complete lower.
With that being said everything and I mean everything I have gotten from PSA ( except for other name brand parts ) I have either had to send back, modify it or just plain scrap it. So I believe AP is leaps and bounds ahead of PSA in quality control, fit and finish and overall quality of product. This I have seen first hand. If people want to lump them in with PSA that's their prerogative. However, I think that is a grotesque misrepresentation of their products. Being a former Aeronautical and space parts manufacturer I believe they take a little more pride in their product. Thank you for your kind and overly generous time to read my post. Still friends though!
But Everything else like barrels (most from BA) lower parts kits, bcgs, all that stuff ain't no different than PSA. Probably sourced from the same places to the same specs.
So their basic carbine upper with charging handle and bcg, and A2 front sight ain't no better or worse than PSA's. Just cost about $150 more right now.
