Yes, that's my fault for not reading more in-depth. However, when I see a collapsible stock, I assume it's going to collapse all the way. Not a huge deal, but it's kind of silly to make it look like a collapsible stock but not actually function as one.
Anyways, I'll check out the how-to. It looks like with some machine work it would be possible.
As for buying one, do you happen to know anyone who might have them in stock? I've found them at a few places but they all say out of stock.
I've been paying attention to the 922r compliance list and already ordered a few other parts, so I'll be good to go there.
