Through Instagram networking, I came across somebody selling 80% lowers for $65 each. First question, is this a decent price?

Second and the real heart of the issue.. I'm completely new to "building" anything firearm related. Exactly what must be done to/with this lower? What tools would be needed? If I understand things correctly, I couldn't even have somebody (or pay them to) help me with any aspect of this unless they're licensed for mfg'ing weapons.

From the few I've seen done, they were drilled out using a drill press with the help from a jig you need to buy, and it showed. (Not pretty at all) but they functioned. These will come with no S/N and considered a home built gun, which I believe can never be sold and is only for your use only. Prices on these have also creeped up as everything else. I used to see these around the $40.00 mark. IMO If you plan on doing a few, it's not worth it, considering the cost of the lower and the jig outweighs the cost of a stripped lower in even todays inflated prices.

I have heard of groups of people having CNC machining "parties" where guys with 80% lowers will get together and rent out a CNC machine. All of the dimensions needed to complete the lowers are put in the machine and the owner of the lower just needs to press the button to start the machine for it to be considered home built by the person.

I'd just be making one for my use only. I can deal with a little an ugly duckling if it functions well. :) Thanks though I'll look into that.

Hmm... never heard of such a thing but I'll look around my area and see if I can find something like this going on.

This isn't a job for beginners. Spend an extra $30 and get a completely finished lower.

Go ahead and order a parts kit, and wait for it to come in.

I believe the whole point for those lowers is to have a legal firearm that has never been registered or had a serial number associated with an NICS background check form. Or at least that is the main appeal to alot of the people that are buying them.

Oh, I know. The OP just said in his first post that he wanted to do a build, that's why I posted what I did.

Do want a lower, or a lower with no serial number? If the answer is the former, get one from PSA. Blems are in stock right now, otherwise they come in stock about once a moth since they do not take backorders. If you the answer is the latter, that is a good deal provided you are confident that you are getting a reputable brand.

From what I've read, you're probably right but I enjoy challenging myself. I gotta start somewhere, right?

Indeed. I could easily just go out an buy another AR, but I'd like to challenge myself and have fun doing it myself.

It is a challenge and there is nothing easy about it.

To get an idea of the equipment needed to do it properly, look here.

Index of /ar15

Its time consuming and if you dont have a background in machining, you wont understand a lot of stuff.

I've done it. Mine came out great, but I have a full sized milled with a digital readout.

edited to add:

this is for a zero lower. I just noticed that you intend to do an 80% lower. Carry on.

Sometimes you think you are saving a few bucks in the end it gets costly and disappointing.
This often happens with weapons and motorcycles. I do have a bit of experience.I would let this deal go if it was my cash.
