These 80% AR-15 Lower Receivers start as 7075-T6 forgings from the lead forge in the US and all completed portions meet mil-spec tolerances.
To make this into a functional AR-15 lower, you will need to do the machining for fire control group are and trigger slot and drill holes for the safety selector hole, trigger pin and hammer pin. This does not require an FFL. This is shipped as a a do it yourself item, and will require that machining work to be functional. Many youtube videos and other tutorials are available online to help you complete these steps.
This is does not count as a firearm according to the ATF and it will ship directly to your home.
