Why the FUCK do you need to be 21 to purchase a stripped lower receiver??! I was all excited to start my first build. Ordered an Aero stripped lower and was doing a bunch of research to find the best, most cost-friendly parts. Then, I hear that you must be 21+ to pick up a STRIPPED LOWER from an FFL. That is the dumbest fucking shit I have ever heard. I mean, what's preventing me from taking the lower off of my legally owned AR and slapping a short barrel on it? Literally nothing. Fuck this. Guess I'm either gonna have to wait half a year until I turn 21 or buy an 80% lower and figure out how the fuck to work with that.
Here is my obligatory gun image so this doesn't get taken down.
And yes, I know this is an Arby's you fucking 'tists.
Update: Thanks for all the advice and help. Just ordered two 80 lowers and a jig. Time to get to work boys.
Buy an 80%, get it shipped to your door, and finish it on a mill. Unless you're in CT or HI you should have no problem.
I live in a relatively non-commie state so I'm considering doing that. Not very mechanically savvy though so I got a lot of research to do. Also mills/drill presses/routers are pretty expensive but I guess it's worth the investment.
There are ghetto fixtures you can set up to use with a hand-drill for your pin holes and a router for the pockets ($300ish), you can buy a ghostgunner (CNC mill set up specifically for AR lowers) for $500, or buy a legit minimill for $1000-2000.
Thanks for the advice. Turns out my grandpa has a router though and he's going to let me use it.
