Looked for my manual yesterday, couldn't find one. Don't remember if I ever had one. Anyway I have a D-Technik VZ-58 and want to know where to apply oil/grease. Having no manual, I applied white lithium grease to the rails and lug contact points, light oil on the gas piston, light oil on the bolt with exception of firing pin. Ran oily patch through barrel, then a dry patch.
