Good milspec parts - Aero Precision AR15 Lower Parts Kit, w/No FCG/Trigger Guard/Pistol Grip

I used this lower parts kit for a Aero lower I recently purchased. This parts kit will work with other lowers too, but whats nice about this kit is youre given a threaded part for screwing in the spring and detent for the rear take down pin. I like this QOL part/feature from Aero.
