Just what the title says, I have an adjustable stock for an AK. I pulled it off my Romanian and replaced it with a Magpul fixed stock. Just wasn't my flavor. Looks like it has some kind of recoil reducing spring mechanism in the "tube" as well. It can be made fairly short or really, really long. Far too long for my 6' frame, but nobody ever said it has to be fully extended. It can be yours for the low low price of $20
