Cool, thanks. Someone told me its for an AK and I said no it wasn't but did not know to which gun it was for.

That's the crappiest way you can put a scope on an sks.
The top cover wiggles around so your scope will be aiming a different direction than your barrel for every shot.

And please, please just leave that poor SKS alone. No tacticool upgrade is gonna make it into a tack driver, and once you put the crap parts on it, nobody will want to buy it from you.

Rant over. Sorry for the aside.

This. I know because I tried. In the end it went all back to stock.
