It's something - FAB Defense Recoil Compensating Folding, Collapsible Buttstock System for VZ58 - Polymer Joint

I hate when I'm really excited about an order and when it comes in I'm kind of let down. That happened with this product.... I'm not totally deflated but I expected more for the cost and better quality from FAB.
PROS:
Looks good
Push button folding mech is easy to reach and manipulate
Folds to the left of the rifle unlike the original stock
It doesn't hurt to shoot anymore

CONS:
The folding mech in some kind of poly and I prefer some parts to be steel
the stock wiggles a bit on the "fake buffer" tube. I have the same stock on an AR and it is rock solid. After inspecting the tube I realized it is a bit thinner than the Mil spec buffer tube. Come on FAB! That's an easy engineering oversight.
Not cheap. I bought mine on DVOR so I got a good deal but if I paid retail for it I would have been more disappointed.
The mounting block doesn't fully seat as it should. It's functional but a there is a hairline gap between it and the receiver.

Bottom line is the original bar stock freaking hurts to shoot if you have a check weld. This fixes that problem. With a bit more attention to detail this could have been an awesome product but as is... its mid.
