NSZ85 Build Your AR-15 Lower Receiver!

NSZ85's videos helped me when I started building ARs back when. He hasn't been heard from since December of 2020, and YouTube has started removing his videos... so, I figured maybe other people might appreciate them like I did.

I do not own these and if anyone knows how to contact NSZ85 please let him know that I'd love to talk to him about these...

The guide he refers to is located at https://www.ar15.com/guides/files/tutorials/assembly/lower/index.html
