These were standard issue with the VZ-58 when equipped with the IR illuminated active night vision scope. The flash-hider is more to protect the shooters eyes and optics from the flash as opposed to hiding it from the enemy. This is essential night-fire equipment.
 
If the Gun-Kote finish units are out of stock, make a request if you want one.
