Ken, brother ARs are so easy to build a cave man could do it
A fucking retard could build one. Just look at Gay Patriot.
Seriously, though, GAP knows more about firearms than anybody ever ever met and talked to, not to mention knows how to basically build them from scratch. He could walk into a hardware store and come out with some shit that would make a functioning firearm, probably slam-fire open bolt full auto, but you get the point.
When I have a question, I call him.
