Man Makes 21k at gun buyback with 3D printed guns.

On that note, I thought I'd mention P80 is Buy one get one free on compact lowers.
Add one to your cart, two will show up.

You can 3d print the jigs or buy them for $25ea from some other place.
At some point I'd have to think you have too many 80% lowers for them not to think you're manufacturing wepons but... that's a later problem. :lmao:

I don't know what the limit is, but I may or may not know someone who has purchased... several frames with jigs at one time, but not from polymer80 directly... and no dog kickers yet.

I'd probably make sure you never purchase a whole firearm's worth of parts from any one vendor in a calendar year.
