Your APS-2 doesn't come with a front sling mount?
If not go and get one, then look at the bi-pod. You see those little fingers that stick up through the bottom of the pod? There are little pins on each of those fingers. Those are what go into the sling stud. When those are in the holes, go to the other side of the pod, and turn the thumb wheel. Turn until snug.
Open and close the pod a few times, as you may have to re tighten the thumb screw. After that....you are good to go
