or a machinist friend.
But mostly, when it gets ugly, its going to get really ugly and not much is going to matter RE records or such.
Thats assuming you don't give in when they come for the first evil objects....

A little piece of paper that cost I think $200.00 plus you have to fill out a form 4, and wait 6-12 months before you can pick it up.

One thought about some of the 80% lowers out there right now - if you're going to do one (in aluminum), at least get something that's already hard anodized. You give up a lot of wear resistance with the bare aluminum lowers. Even with an anodized 80%, the trigger pins still wear against bare aluminum, but at least everything else is protected.
Polymer is a different story of course. Much appreciate the straight forward tech advice you share here... So would Polymer be better in this case? or not a wise option to consider at all? Thank you. I'd expect a polymer lower to wear less than aluminum, Nylon 6 (which most of them are made of) wears pretty well actually. You can use anti-rotation pins to eliminate the pin hole wear in an anodized 80% lower. Cerakote is a pretty poor substitute for hard anodizing though. The wear resistance isn't nearly as good. I'm with rost though; the 80% stuff just isn't worth the time, unless you just want a project. Good complete lowers are the way to go for me.

Make your decision on the completed lower you want.
Go find it on armslist in your state.
Buy it with no paperwork.
Ain't really no justification for 80% lowers anymore.

Polymer lowers are much more fragile than aluminum lowers. If you're going to do an 80% lower, start with a 7075 forging. They do cost more than many finished lowers, but you'll have the satisfaction of having machined it yourself

I'd love to figure out how to machine one out... maybe after I hope to learn to rebarrel bolt guns...
It would be fun, but negative profitable.

They aren't worth the $35 their lowers cost, never mind the FFL fee. I sure wouldn't pay $100 for an unfinished version.

Hi all,
While I have to admit that I haven't read all of the responses to this post, I HAVE just recently finished a 80% Polymer 80 lower receiver, using a drill press, 4"x3" XY vice, and a dremmel tool. I used a RRA lower parts kit.
The actual process was easier than I thought, as there are many YouTube videos to show you the process. A good pair of dial calipers, and a complete lower receiver on hand, for a visual and mathematical reference is also a good idea.
My opinion, don't waste your money. I was expecting the quality of the "plastic" (polymer) to be equal in quality (toughness) of the lower of my Glock 17, but it's MUCH softer. There is NO comparison to my Colt or Stag lowers, and while it will probably work (haven't fired it yet), I feel like any side-to-side pressure on the completed weapon will crack it in half like a plastic water pistol. I MAY just leave it unused in the safe, OR I may get a .22LR bolt/carrier/mag assembly and have an AR/22LR. I have a second one, that I think I'm just going to keep (unfinished) as a conversation piece.
That's my honest, unabashed opinion. YMMV

whats wrong with their lowers? Other than the hour or so needed to deburr everything and clearance the lower to fit your upper - their lowers hold a mil-spec upper off-center at the rear, because of where they positioned the recess for the rear lug. I sent mine back twice, the first time the replacement had the same issue; it's still back with them again, on my dime. Like this; it rubs the bcg against the buffer tube:
