What are my options for true mild steel buffer tubes? Not looking for a kit or anything, just a tube to do some tinkering with.

Well... that's a bit too expensive to play around with isn't it?

Thanks for looking!

Not much point if you don't also have a steel receiver.  What good is it if instead of bending the tube you break off the receiver?

Maybe help balance the rifle?
They make lead bars that fit in the fixed stocks.

Was going to use it to make a prototype stock instead of having to make one out of aluminum. I don't have my TIG setup here, so I'm stuck working with just steel...

If you are prototyping a stock wouldn't any steel tube if the right diameter work?  The other alternative is to build your own using the correct dom steel or seamless tube.

Indeed. I would like to have the correct size threads on the tube also. I'll have to do some caliper work because I bet the buffer tube isn't a normal size

I gave up after about 15 minutes of searching, but somebody on weaponsguild.com built a steel AR and sourced a steel tube for the receiver extension from Amazon, I think, but it wasn't threaded, he welded everything together.  I thought he started with a flat spot lower kit, but I could be mistaken on that as well.

On my a2 receiver extension I measured the tube at 1.106" od and 1.000" id.  The ring that seats against the receiver is 1.304".  On a pistol extension, I measured the threads at 1.180" on the tops (diameter) &16 tpi.
Hope that is helpful.

There were several of us working with the Flat Spot lowers.  I was using tube steel from Amazon Supply, here is a link Amazon steel tube.  

Some pictures also in that thread; Steel flats

After looking at your link, that may be the one I was thinking of.  Can't retain everything I read, yet alone where I read it.

That would work if I could thread it...

The OD happened to coincide with the ID of the flat spot receiver pieces.  The ID of the pipe was a match for the buffer.  Depending on your application you can order a different thickness pipe with the same ID.  The raw materials are inexpensive, but you'd spend a ton on the die to thread as you describe, not to mention all other associated tools.

This looks hopeful strictly based on description, but Airsoft. . . .Buffer

Someone in the comments mentioned that airsoft one was a UTG. Probably aluminum then.

...and not to go off topic, but holy shit- Amazon has a supply branch? I'm in heaven.
