Building an AR-15 is a lot of things. It’s fun, it’s educational, and it’s easy. "Easy" is the keyword for a lot of people, especially those who even consider themselves to be mechanically illiterate. Even when it comes to building an AR-15 from an 80% lower it’s not difficult. I’m not going to lie, it can be scary and a little stressful the first time you finish an 80% lower. However, you don’t have to be an engineer to build an AR-15, and you don’t need to be a machinist to finish an 80% lower receiver.
