I'm currently putting together an AR pistol in 9mm. I purchased an extended buffer tube, but I am wondering if the standard carbine spring will work?
Thanks for any info.

Damn that tube is LOONNNGGGG! If the inside is about 7" deep it uses carbine parts.

The inside runs the length of the tube. 9"

I bet it doesn't open up to full diameter till a couple inches past hole in end, just like the KAK.

There should be a plug in the tube so that the interior is the same length as a standard carbine tube. Use a standard carbine buffer and spring.
