They're pretty darn good right out of the box. I'd recommend replacing the AK style slant brake, or re-notch it to to the 6 o'clock position. The Slovak style brake seems to get good reviews and is 'period correct' for VZs. There are several good threads on cleaning & lubing a stuck stock hinge, read up on them so you don't strip your threads while unsticking it. If you want a more comfortable stock you can wrap yours in paracord, or add a rubber butt pad from UTG or Zahal. The UTG is a copy of an AK grenade pad, thick & cushy and twice as wide as the stock butt, but won't allow the stock to lock up folded. The Zahal pad is smaller and more like hard plastic and allows the stock to lock up folded without scratching your receiver. If the stock grip is too small there's a few aftermarket rubber grips out there as well. And buy lots of ammo.
