A question about 80% lowers Login/Join

I'm thinking about picking up a couple of 80% lowers for a build. I ran across a site that claimed that the BATFE decided that you can machine these things with your own tools, no problem, but your buddy can't loan you his, or let you use his shop.

The info was from 2015, and I couldn't find anything corroborating it.

Is this fact or myth?

It's my understanding that you can no longer hand your 80% receiver + $XX.00 to a CNC (or manual) mill owner/operator and have them hand you the finished receiver. If it's a CNC mill I believe you are prohibited from paying to clamp the 80% receiver in a fixture and push the start button yourself.

I am unaware of any restriction on using/borrowing another's machine (or tools/tooling) to complete an 80% receiver; so long as no money changes hands. That is, so long as you are not paying for the use of the equipment or anyone's assistance. You have to complete (manufacture) the receiver! So far as I know, you do not have to even own a file (much less a machine tool) to legally complete an 80% receiver

I have seen 80% AR receivers finished on a decent quality drill press. It's not the best machine for the task -- but it can be done, if you are careful. I don't recommend it. A "bench top" mill would be much better. I own a Lagun (Spanish Bridgeport w/DRO).

Why don't you write the BATF and ask for clarification. They will tell you what you can and can't legally do.

It's really handy to have a friend/acquaintance with access to machine tools! You'd be surprised to know how many guys have a machine (or three) in their garage or hobby shop.

It has been my understanding that as long as YOU do the work the source of your tools is irrelevant.

What is the purpose of an 80% lower? I just picked up a couple of stripped Anderson lowers for $40 out the door, sales tax included.

80% lowers are for chumps.

The government can't actually keep track of firearms, and the idea of a national database doesn't account for the cost.

Thanks to all.

Just in the initial research phase, undecided as to whether I'm going this route or not.

Really just looking to do it for the sake of it, not for any financial reasons.

OP, you do realize you will need specific jig for the work to be done...that adds to the cost. And you have to figure out how to anodize it when you are done...

It’s not worth all the hassle when you can get a receiver for $45.00

Yes, I've read far enough into it to figure out that it will be something of an investment if I go through with it.

I've about talked myself out of it at this point, may be something for later on for the entertainment of it.

No you don't as an absolute. I did mine without a jig. but on a mill. depends on your skill and tools.
"And you have to figure out how to anodize it when you are done..."
Again, the degree that this is an issue depends on your goals. You can buy 80% lowers that are already anodized. You can anodize it yourself (its an easy DIY project). You can send it out to a vendor who anodizes as a business many accept small orders. You can coat it with something else. You can just let it be without any downside other than color.
My point on the above is that these are not major issues if you want to build one.

I'm editing this to add that it was an enjoyable project for me. Took more time than I initially thought, but I really went into the measure 20 times then cut mode. Repeating it would be way less time, but as others have said its fun to do, but if I need another lower I'll just head to my LGS...
