I recently purchased a new AR-15 but want to add  a collapsable stock to it.  I know that this stock must be permanently pinned so it will not violate the AWB.  Can someone give me an example  of what ATF considers permanently pinned?

As you're already aware, you can't legally add a collapsable/telescoping stock to your new rifle. You can change to a fixed tele-style stock. Looks the same as a telescoping stock in the extended position but does not move. Most of the major manufacturers have them available. If you go to the Industry forum you will find the links.

Permanent means that it must be welded according to an BATF opinion letter.

I have YET to see a welded fixed collapsable stock...

Muzzle brakes can be silver soldered on.

You can't weld plastic to steel, so you won't see any soon.  I think the look alikes are pretty silly anyway.

I am just saying what the letter stated. I haven't seen a welded one either. The ones I have seen have had the full length lower extension in it.

Can you give us URL to the document that you are referring to?  I have not seen such a document that talks about stocks needing to be welded.  I have heard about one for muzzle brakes.

Another member of this site submitted a letter and this is the response he got. He sent me the images so that I could post them.

Photos.ar15.com seems to be - I cannot access it.

Will try again later.

All the early "fixed collapsables" used regular collapsable stocks permanently fixed in the (usually) open position. For some reason, I also wanted one fixed in the closed position (boat gun), so I got one--before the "entry stock" thing came around. Guess I may have been a trend setter, huh? Only recently have the manufacturers begun using long buffer tubes.

Since "welding" an aluminum buffer tube to a plastic stock is not possible by using traditional heat/current and welding rods, it would seem that it could be argued that "Welding" wouldn't necessarily have to mean welding as we think of it. How about "permanently bonded"? The early ones used a bonding agent of some sort, probably an epoxy, and a blind pin, and there is no way you could ever get them to function as a collapsable, even by tearing them to pieces.

I would think that an epoxy would fit the bill asd it would permantly fix the stock in one position.

Thank you for posting.  It is most appreciated!

I have seen various stocks and all seem to use 1-3 blind pinnings along with epoxy.

Epoxy is probably the "weld" in this case.
