I didnt go to the last WAC gun show, but there was a guy selling 80% lowers at one of the shows. A machining party was arranged where you rented a CNC machine for 15min and were instructed how to do the work... Pretty slick. Something like $150 total
I have seen some polymer lowers that were 2 tone so that it was REALLY easy to do with a dremmel. You can buy the online stencils and make one with a drill press and a dremel even with an aluminum one.
Ive never done it but looks easy.
Palmetto state armory had a sale back a while ago and you could buy a muliticaliber lower for $55. shipped to your ffl
