2 point sling on cronus tactical

The Cronus has a built-in sling loop on the standard butstock and 4 picatinny rails which can easily accept a quick-detach sling loop.

Now, it's not my marker, so far be it from me to tell you what to do with yours, but I've found slings to be next to useless on most markers. They're light enough to not need one, and when slung, you usually do something that opens up the hopper lid by accident and lose all of your paint since the hopper is then vertical. They may look "cool" but when you're humping it through the woods, they easily get tangled up on branches and bushes as well.
