I've had really bad luck with the O-rings on the Rage broadheads. I LOVED the Rocky Mountain Snypers...their predecessors, but I just can't get the blades to stay in place (closed) consistently w/the newer version (Rage). They're constantly popping out of the O-ring when I put them in my quiver, take them out, etc.

Magnus Stingers don't have any of those issues!!

Good luck.
