Yeah. Screw that. I think I will just keep it as the curiosity/conversation piece/paperweight I bought it for. A lot of crap would have to be done to make the thing on the right work like the thing on the left.

How much?
Link Posted: 11/21/2008 6:46:58 PM EDT
I'll give you $100 each for every one that you can make. How's that for an accolade?

I'll give ya $50 for the ugly black one.

$25 + 10 shipping. Not great, but it was one of those things that was to neat not to buy. Got it on the EE.

An 80% you can finish in your garage with some handtools. A 0% is going to take a lot of whittling.

I've got a few stag LPKs. I'll sell you one for $150.

This looks like a job for Dremel Tool!!
Link Posted: 11/21/2008 6:59:30 PM EDT
I've done it. I used an Enco benchtop milling machine (their largest benchtop model) that at the time cost about 800 dollars. Tooling extra. I made two, one is useless in the
extreme, and the other is the receiver on my very reliable and very accurate 20" A2 HBAR type rifle.


I've got two more lower forgings just sitting here, and in a few days it'll be three of them,
plus one each raw forgings for flattop and carry handle uppers. I've got a plan...

I actually wouldn't mind one for a paperweight
Link Posted: 11/21/2008 7:04:13 PM EDT
Other than a doohickey I have no idea why I want one.


But I want one.

Couple of grand? Naw.

Convert a Seig X2 mill (about $550) to CNC. All told, $1300 bucks + some time/effort.

how much is an 80% lower? where to buy?
Link Posted: 11/21/2008 7:24:39 PM EDT
Just a few months of evenings sitting in front of the TV with this chunk of aluminum and a dremel. Start it out with a drill press first though, for the stuff that goes through and through.

Aren't the magwells cut with a broach? How is that done with a mill?

It will cost more than a 100% receiver.

what is pictured is a 0% lower. An 80% lower has way more done to it. You can search online for 80% ones but they are out of stock most places.

Drill the corner locations (long drills needed, I used 1/8" size) and use the longest
end mills you can find. I still had to flip the receiver over to finish milling the magwell
but I got it done. I finished out the inside of the well with files to get a nice uniform surface.

It's time consuming but not particularly difficult.

na, you could do it with a dremel.. may take quite a while but its possible.
Link Posted: 11/21/2008 7:54:00 PM EDT
You could probably do all you need with some files and calipers. Maybe a drill. Old school machinist used to take a hunk of steel and have to file it to a perfect 1" cube to pass a test.

That would be awesome - just keep working on it an hour at a time till you get it done.

I run $100,000 mills all day long. AND write my own programs.

May have to look into one of those.
Link Posted: 11/21/2008 7:59:57 PM EDT
I bought one back during the ban with intentions of finishing it. It's still sitting in my safe even though I now have the equipment to finish it.

0% is easy

I would like it at work on my desk, because nobody would have any idea what the hell it was-except for the few good humans.
Link Posted: 11/21/2008 9:16:09 PM EDT
I have 3 on order.
Link Posted: 11/21/2008 9:40:29 PM EDT
Thanks, I ordered one too.

I tried that when I fluted the barrel on my AR. It didn't go over so well
