yugo sks gas chamber settings
 

I just acquired an Yugo SKS that has the grenade launcher on it. I am planning on purchasing a golf ball end for it. I know that you move the gas chamber selector to the downward position for regular shooting, but do I move it just up for grenades? or do I move it up and then back? with the gas piston in I cant move it backwards and without the gas piston it it will but then the pin falls out so I am assuming you just move the selector up to the 12 o'clock position for grenades and then down ward to the 4 o'clock for live ammo?? is this correct?

Yep. That's correct.

That's correct. In the 12 o'clock position it prevents gas bleed-off so youget maximum gas pressure directed at launching the grenade. Don't forget to use blanks..lol

PS - Where can you get a grenade launching adaptor? I've been looking for dummy grenades to lob around...

P.S - I've been told that when firing grenades you don't want to "shoulder" the weapon!

you can get one here. I've seen other websites as well. http://www.laxin.net/Launcher/

10-4 man they're right. Don't forget to switch it back though, the first time I fired my grenade, i forgot to switch it back and i thought my rifle was missed up cause it wasn't reloading. Figured it out pretty quick though. Oh by the way, if you're gonna shot your dummy grenade in a big field, tie a piece of orange sting to the tail, so you can find it again. Took me a month to find me.
