I originally posted this for just the stock, but I pulled out the VM-68 and figured I would sell it too. It leaked, so I took it apart...then I didn't mess with it again. I would go for a complete seal replacement and it should be good to go. Also, it comes with a new J&J Ceramic barrel. One of the plastic caps for the side was cracked when I got it. I am pretty sure I have all the part with it, but I am selling it as parts. If for some reason I miss something, I can track it down later and ship to you.
As for the stock:
Look at the bottom VM on this page: www.vm68.com: Custom VM-68s
Apparently this is rather rare:
It is in good condition. Been sitting in a box for a couple of years. It is very rugged and mounts to a VM68 securely. I have a parts VM68 I can sell with it...I will get some pics of that soon. It is in pieces, needs seals replaced but in decent cosmetic condition. Not sure what to ask for this, it is rare...How does $125 Shipped OBO for everything.
