80 percent Ar15 lower question

[Duck_hunter11]

Anybody done their own machining on a 80 percent? How hard is it?

I have seen several that have been done. Seems easy enough. I just don't know what I would do with it for the paint job, after all I don't want a bare aluminum lower.

A buddy of mine is going to order 5 of them and give me 2 for doing the machining. I've watched some videos and it is fairly simple. I am machinists though and have the mills and tooling to do it. If you have a decent drill press and a vice you shouldnt have a problem doing it in a garage. You will need several different size drills and a couple of end mills

I just finish machining mine this last week, bought the jig for a drill press. all you have to do is make sure the drill press is level and you go from there (took about 3.5 hours). I will be sending this off to anodized this week or next for 30-40 bucks

It's not difficult if you have the right tools and GOOD prints to work from. It is a very time consuming process. I'd be hard pressed to ever do another one myself considering how cheap you can pick a finished lower up for right now. I'd certainly not enjoy trying to complete one using a drill press.

It was that bad? I was looking at using the jig and a drill press. just kinda something I want to try and see how it is

Do you know who he ordered them thru? If you don't mind me asking

[cuttingedge]

I have seen them for sale 5 for $299 and the jig for about $60. The ones I saw were already anodized. I felt pretty confident I could complete them myself if I ordered them.

Don't remember the website but it was easy to find with a search.

I have the tactical machine jig and have done a couple of 80s on a mill. Not hard at all, tolerances are crazy large as far as machined parts go. I have mine cerakote usually.

You can do your own electro etching. Do a Web search there's some great tutorials out there.

Take a look at modular arms jig, milled with router, no drill press jumpimg. I am pleased with the way mine came out.

Not hard just need not rush it.

So to only advantage to this is there is no record anywhere that you have the lower.

Is there any restriction on selling it the rifle after it is finished.

I think it says for your own use?

Just looked at a Brownell's advertisment. They were more expensive that 100% lowers..

From what i've researched on selling....as long as you are not building with intent to sell (you own it for some time), you can sell/give it away. There doesn't appear to be any time you have to "own" it for. it's still rather a gray area.

There are a lot of 80 %'er sites out there

Only regulations on selling are you can't build with the intent to sell, and you have to mark and serialize the lower. Technically you are the manufacturer at that point. I believe it's your name, city state, serial number.

I mark and serialize all of mine from the get go. In an effort to avoid an uninformed officer. "This gun doesn't have a serial number. All guns are supposed to have one. Ur taking a ride." As slim as the chances of that are.

Where did you hear you have to mark and serialize the lower if you sell one? First I have heard of this.

I'd advise against trying to use a drill press, they are not made to be loaded laterally like a mill. Not sure when you start stressing it and you get a little chatter how safe it will be running an endmill in a jacobs chuck.

I don't see the benefit of doing this when you can pick up a blemished lower from PSA for $70. Everyone that I've looked at the 80% lowers are basically the same price if not higher.
