I want to understand what you guys are talking about because you seem really excited but I have no clue, really. I mean, yeah, I have guns but I'm assuming you're buying some kind of "some assembly required" kits or something?

An 80% lower is a chunk of metal that can be turned into a lower receiver with some milling. Any closer to completion and the lower would be required to be sold by a licensed dealer, and have a serial number.

Its important to understand that the lower receiver is the part of a rifle that is actually considered the gun. The other parts of a semi-automatic rifle can be sold without any sort of regulation.

The lower is the part that houses the trigger assembly, is what the stock and grip attach to, and is where the magazine passes through to feed into the upper receiver. The upper contains the bolt, attaches to the lower, barrel, and a bunch of other levers and buttons that aid in the operation of the rifle.

There's more to it than that, but hopefully that gives you an idea of where the parts are located.

As for the legality of purchasing and completing 80% lowers, I wont comment because I'm uneducated. Check local and federal laws.

Wow, so I if I were interested in doing such a thing, I'd not only need the parts but need to also get some tools. Aside from the joy of making your own gun, I assume that you might be able to save money. Ostensibly, you wouldn't save much if you had to buy tools the first time too so you'd likely want to build more than one, right?

Thanks, by the way.

Correct. It's possible to complete an 80% lower with nothing but a drill press and a few bits. There are even metal templates that can be bolted on the the 80% lower that make it possible to complete with just a normal drill and bits, but I'd wager that's harder.

I assume that you might be able to save money.

If you own the tools, yes you might save a few bucks (if you ignore what your time is worth). Besides the sense of accomplishment, the appeal probably has more to do with owning a firearm that the feds have no record of. Again, check your laws to be sure, but there's no law that I know of which prevents you from manufacturing your own gun for your own personal use. On the other hand, selling or transferring such a weapon would be a huge fucking felony.

Thanks, by the way.

Happy to help. Be safe, and check those laws.

Well now I'm most certainly interested. I assume you could make guns that you would not normally otherwise be able to purchase, I assume. That's so very interesting.

Well this is actually a grey area, albeit a very dangerous one.

One may not produce a firearm FOR sale. This is known as manufacturing. If you produce one for your own use and sell it at a later point that may not be classified as unlicensed manufacturing. Again, it's a grey area and one must proceed at their own peril.

Moderator and creator here.

I wouldn't bother with manufacturing a lower for the purpose of sale. Way to much legality and defeats the purpose. You would have to serialize it also do the proper background checks to the buyer with ATF.

I made AR with a drill press. Now the jigs are what is going to make this fun or fucked. They are really hard to find as well. Lower parts kits are easy to find and even the 80% lowers for AR is.

If you wanna go this route I suggest you go with billet as opposed to Forged aluminum and polymer for an AR15 is not recommended. Just too much recoil to often that is can't deal with it.

The AR10 for such actually was told long as you use a drop in trigger isn't that bad.

As the other guy said the uppers are not regulated and can be shipped right to your door.

The reason I got down this route was simply because I see regulation happening in the near future, and I don't really see the need for me to be defenseless.

There are many other models of firearms you can make too.
