They're awesome. A step up from psa although those aren't bad either. The m4e1 is the way to go. Mates well with their (and BA's) uppers.Does anyone have any experience with Areo Precision lower receivers? Any good?
I used to buy and build using Anderson Arms parts...now it's Aero Precision all the way!I only use Aero uppers and lowers for builds anymore. The price to quality ratio is just about perfect IMO.
