Fab Defense M4-VZ P SB stock for VZ-58 rifle, M4 design, robust and designed for combat! Left-folding mechanism (reinforced polymer axis) – designed for extreme use, locking in the “open” position is done automatically by a simple pull on the body of the stock. In the “closed” position, shooting is facilitated by a design that ensures immediate access to the trigger. The piston at the end of the stock allows significant absorption of energy – even in the automatic firing phase – for a reduction in recoil reduction of approximately 35%.
