Does anyone know what this is?

I think its a grenade launcher sight, but I'm not sure. I do know its Russian though. If you guys know what it is...can you also tell me how to attach it onto my rifle?

Is there supposed to be a picture in your post? You'll need to describe what you are talking about a little better if you want help with this.

Oops...I always do that.

Well, the main discussion on this thing is in the "build it yourself" board. None of us can figure it out. =/
