RS Regulate is about to release the VZSA, a stock adapter that is sure to please VZ58 owners. This adapter allows installation of the Magpul Zhukov folding stock on the VZ58 and maintains full safety function when folded. The Zhukov stock represents a massive comfort improvement versus the standard VZ58 folding stock.
Prototypes of this adapter have already been shown and RS Regulate states that the adapter should be available shortly. Check out RS Regulate.
