i may have the pictures mixed up but you'll see the slider that you put a
bullet in releases the stock..Another shows the lever inside the trunion
to close the stock, & the hook on the left side

don't know why they came out like this they were clear when i checked them. The lever inside is at a 45 to a plate that is part of the outside hook
just learning to post i'll get sooner or later

I have played with a few.

The modern ones are different, but the best I can figure is that the RPKS type folder was not designed to be folded back and forth like an AKMS... It was pretty much to be folded once for the jump.....

rob, i have to agree with you on the folding part because the push button spring is hard to push not some thing you would do all the time
