I have gotten into the 80% build for ar15 and 1911. Article is kind of an ad for tactical machining. It is considered manufacturing a firearm., specifically forbidden by state law. The 80% lower version of ruger’s venerable 10/22 from tactical machining is rarely in stock and has some more difficult steps since the barrel will mount directly to the receiver.

I’m surprised you didn’t mention tacticalmachining.Com for 80% aluminum lowers or eparmory.Com for polymer.
Their manufacturing process is also really cool. The 6061 aluminum also made it possible to do deeper milling cuts each time which saves time . 308 80 Lower 7075 is the standard for “real” lower receivers but the difference in strength is so little that I doubt someone could break a 6061. Meanwhile, an 80% lower is technically not a firearm until you finish machining it, so you can get them delivered straight to your house without paying ffl fees. If you’re buying a finished ar lower, you’re technically buying a firearm in the eyes of the atf. Tldr; an 80% lower receiver is an unfinished lower that is nominally sold as a “paperweight” or other novelty and not a firearm. Today, we’re going to go over the best 80% ar-15, ar-10, and ar-9 lower receivers out there.
Uh, if you buy something that is more than 80% finished, you are buying a firearm. Also, if you have your machinist friend finish an 80% for you and you take possession, you are both in a heap of trouble. Yes and no, if you want complete protection then yes it should be. However, since it is aluminum to start with and that area doesn't really have anything that needs to be protected - it is easy to get away without doing anything to it.
Next time maybe actually get some lowers mill them out use them for a while and then form an opinion . Easy jig 2 and lowersthere’s a good amount of choices for 80% lower receivers…from 6061 to 7075. These are our favorite 80% lower manufacturers and jigs. However, if you still want to do it old school and have a drill press and more time (to save around $70 compared to the ar-15/ar-9 easy jig)…anderson has their 80% jig. We recommended getting the drill bits kit since it does need a special end mill. Or if you want to save a little money…get the end mill and the other things at home depot.
