Alright, this is the easy way to show how to install your sling, with pictures! If you want it reversed and put on the opposite side, the link above can show you how.
First, lay the carbine down where it's safe (and unloaded!) with the right side facing up. You will need to remove the two screws and replace them with the bases for your sling (came in a plastic package with your carbine) in these same locastions. One is the top of the butt, the other the forward most centerline screw. I have highlighted them by sticking a white pen through so you can see where they are.
