If you take a look at the pics I sent you you will see they are not hooked onto the mount. They are over it and keep the mount on the weapon if it gets bumped loose. That method also solves Alex's issue. I have used them very well with both the Rhino and Wilcox mount.
I never hook it to the actual PVS 14, but there is a way to do that also without tension, but you must use tie downs, and it works well although there is some slack. I always carry about four tie downs with me when hunting. They are invaluable.
