Does it work to just use the entire A2 stock assembly, buffer spring etc on a 16" carbine length or might there be problems? Just not sure if I need the stock and tube, then a different buffer and spring or not. Thanks!

You can use an A2 stock on a carbine length upper without issue, but you will need to use the rifle length buffer tube, rifle length buffer and rifle length spring.

I don't use a rifle length buffer, on my two builds, and I have no issues. That is not to say the rifle length buffer should not be used.

I'm assuming you've done something to shorten the internal length of the tube? Not doing so would be catastrophic.

OP: while there are ways to use other parts, just get the full A2 stock kit (or even better, M16/A1). It won't cost you more than $65.

How would one go about to shorten the internal length of a buffer tube?

Cutting and welding is not a good option. Why not add internal spacers so you can use carbine spring and carbine buffer?

You really want to use the A2 buffer with an A2 stock, but if for some weird reason you just refuse to do what's right, you can use this spacer to make a carbine spring and buffer work:

But don't do that. Just get a full A2 stock kit. It will come with the spring and buffer. Use them.

I have a A2 stock lower with a middy upper and I have a M4 upper with a carbine collapsible stock lower. I switch uppers back and forth on both lowers with no problems. Mark

I have a M4 upper and a A2 stock and it works fine. I switch it back and forth with another lower with a collapsing stock.

Like adding quarters in the back of the tube. A trick that 9mm Ar-15 users do. This keeps BCG travel to the absolute minimum because of fear of broken bolt catches.
