Aug Replacement Parts
 

I'm sure this has been asked once or twice before, but does anyone know where I can get these specific parts (preferably all from one place):

ST-5 (Barrel Release lever/button)
ST-26 (Spring and Spring Rods for the bolt cover)
ST-27 (Stopper Rail)
ST-40 (Foregrip, preferably in OD)


I've tried contacting Tirador, no answer. I know that the ST-27 is also made by King Arms (available on alot of places), however cannot seem to find anywhere that has the other pieces I need in stock. Can anyone please help? :(
