Sorry this took a little longer than expected, but here are some pictures.
I lined up the body with another AK so you can see the difference in lengths
Fully Collapsed:
Fully Extended:
And here is a picture with the mag in and extended to a length I will probably be using it at, which is extended to the third (out of six) spot.
In all honesty, from what I saw from playing around with it, it is still very comfortable and usable even with the stock fully extended.
