I'm new to this site and new to AR's as well, but I'm wanting to build an AR... Can't be too hard, right? I'm looking for a complete lower (new or used), I've heard good things about PSA. I'm open to anything though. Looking to buy locally to help some guys out instead of going the online route, and avoiding the whole FFL transfer. If you can help me out or just offer some advice, I would greatly appreciate it!
