I have a Rino 750, never been fielded. I bought it a while back for a group hunt that never materialized. I have the original box for it, and it also comes with an FHF Rino pouch. How's $400 shipped sound?
I was removing it and the vertical grip from a CTR stock that I'm tossing. Both the cheekpiece and the vertical grip are going on a standard Lite stock.
I ended up having to punch a small hole in the top of the plug and then prying it out, but you might have success with a pair of needle nose pliers or forceps. Then all you need is a #2 phillips screwdriver to remove the screw.
