Aero Lower
Aero Lowers are simply the best on the market. Parts always fit like they should and the simple upgrades like the screw in pin on the bolt holdback, 4/40 Allen on the rear takedown pin and the threaded pin on the forward assist just make it exceptionally great for the price. Don’t let the bolt guys make negative comments about the AR parts.

Very Nice Lower
Nice but has a different layout so you must get the Aero lower parts kit for the tiny Allen screw you need.
