I just finished putting together 4 youtube videos showing my most recent lower receiver build. In the videos, I break down each step, show at least my way of putting together a lower, and do the entire build from tools that most already have in their tool collection (except the castle nut wrench). Hope these help someone. Enjoy.
I actually watched these after making my videos and learned more stuff, haha. There’s an endless amount of info out there, I guess just find what works for you. I wanted to show how to build a lower with minimal “specialized” tools, since that is where I started and I think most people start.
