Yugo Grenade Launcher

Triplesixkoe · 05-19-2006, 12:16 AM

Ok pretty much every yugo sks has the grenade launcher sight. I was wondering...How do I get the sight free? Right now it is in the regular position and looks like I have to move a lever by the gas tube to raise it up. Do I have to modify the gas tube or anything to raise the sight? I was thinking it would look cool and It's not like I need it. But i tried to move the little knob at the end of the handguard( it looks like that's what's holding it in place) and it won't budge. Someone please tell me what I'm doing wrong.

It's a fire-selector switch. Press it in like a button, and push it to the left so it's on the top. It may be stiff, and you may have to press quite hard. (Don't go crazy though, it might be gunked up- then you'll have to clean it.) Then you can free it and pull the site up. Firing with the switch in this position will be pseudo-bolt action, though. No autoloading because you've basically switched off the gas tube. There's a little cylinder with a hole in there that you cut off by rotating it away from the corresponding hole in the barrel. For somer eason, they needed that to shoot the grenades.

Anybody know why there's also a slot for the fire selector switch to move backwards? ..the slot is sort of an L shape, but I can't get it to go backwards, not that I need to. Just curious..

All 59/66 Yugos have the launcher. Push the gas valve in and to the left, then lift up on the launcher sight and you will be set. If you were actually firing gernades then you would push the valve in and toward you and then you are ready to shoot an RPG. Just remember to put the valve back into the regular firing position before you shoot again.

Don't some people think it's dangerous to shoot it when the gas valve button is straight up-and-down? Why would they think that? In my experience, it just makes it single-shot..

There's nothing dangerous about shooting an SKS with the gas valve in the closed position. The reason it's there is because the pressure curve of a grenade firing blank is such that it would damage the gas system. The gas valve is there to hold back pressures higher (at that point in the barrel) than a regular round, so firing a regular round is nothing to it.

Yeah, that makes sense. Does the grenade firing blank actually propel that huge grenade its whole distance, BRG3? (without anything else to propel it other than the blank) That's pretty impressive if it does.. Thanks.

I think so. It basically throws the grenade. Considering that the same size of shell can throw a 125gr bullet at multiple times the speed of sound, it doesn't seem crazy that it could lob a grenade at least as well as a baseball pitcher.

Yeah, but that grenade looks like it weighs at least a couple of pounds... plus speeding that much weight up to that speed, that quickly, seems like it would kill the shooter too. Or blow up the barrel or something. Admittedly, however, I don't know what I'm talking about.
