Grenade launcher on Yugo SKS

[DadOfThree]

I never really understood how the launcher works. I assume the grenade is mounted to the launcher lug and pressure from a round fired from the rifle launches the grenade. Is there a special round or blank round for this?

Yes - they use a special powder-only (no projectile) cartridge. You also need to flip a lever on the gas port to reduce the bleed-off used to cycle the bolt.
