I concur on an 18" barrel. I concur with a bought upper (at least the first time... and until you buy Go/No Go gauges).

Regardless of what you buy... you will be impressed with how simple and easy it all is. YOU MUST OIL YOUR BOLT... I use 0W-20 motor oil.

Personally, I prefer AKs. This Boris guy is hilarious... built an AK from a garden shovel... https://www.northeastshooters.com/xen/threads/diy-shovel-ak-photo-tsunami-warning.179192/

His pics got cut by PhotoSuckIt... and are below (you kinda have to "back and forth").

If you are not actively engaging EVERY enemy you encounter... you are allowing another to fight for you... and that is cowardice... plain and simple.
