Quality and installs easily - Aero Precision AR15 Lower Parts Kit, w/No FCG/Trigger Guard/Pistol Grip

This might work with any AR-15, but read in regards to Aero Precision lowers it is pretty much necessity. I could be wrong but the quality and price are not bad so it is all good. That said both my Aero Precision builds are fantastic in weight and feel. I mean one build has big boy brand like Wilson Combat and Daniel Defense on it and feel is better on Aero Precision. So if you are building with their stuff maybe just go with their parts kit. I think you can get away with safety selector swapping and mag well release perhaps.
