SPORTSMAN RS2 Think I got one. just a little used. I didn't think 100.00 bucks was to bad.
The RS series is the Chinese versions. They sell new for $150 with a scope and mounts (usually nothing special)

Enjoy the new rifle, if you find that it's something that you shoot often then you may want to upgrade. If it gets shot a few time per year, then that one should be just fine.
