Does what it's supposed to do. Just be careful putting the pin in, I broke the offside tab off trying to put the pin through but luckily it came with a second one for free which was nice. I'd suggest laying it flat on a table while tapping the pin in (friction fit) so it doesn't break off. On a side note, it breaks exactly the way it's designed to if you tried to extend the stock.
For maintaining the original look, this is awesome. It held up nicely for me until an idiot tried to yank the stock open and broke it. So if you ever get one of *those people* harassing you at the range and calling it an SBR, you can break it with a decent amount of force.
The only issue I ran into was that the circular spacer was a bit too long, but a quick hit on a bench grinder got it to size easily.
Thanks for leaving a review Jared! We are aware of the varied stock sizes that are found among various VZ61 firearms. For this purpose we leave the spacer a little long so that the user can use sandpaper to custom fit the spacer to their exact firearm. We hope that you will continue to enjoy our product!
