They work well, I have one for my Tantal (don't like the wire stock). The length of pull ends up being more like a Nato style AK stock than the warsaw length one.
the locking latch works just like the reciever mounted ones, but it rides on the stock. You can see it in the photo on the Kvar site - just forward and slightly lower than the oblong D shaped feature, which is the backside of the main release latch.
the only drawback is that they are fairly heavy - lots of steel.
