How does your equipment attach to the tripod head? If it is like some of the video tripods I've seen, they have a slide-in piece that attaches to the camera (or in this case a gun), then slides into the tripod head and locks in with a lever.
If you had that type of head, you could get and extra one of those mount base pieces and attach one to the binos and one to the rifle in a rail or otherwise, and then detaching one and attaching the other is just a matter of releasing the lever, slide in the new piece of equipment (rifle) and it's locked in place.
At least this way you can mount the piece on the rifle stock where it balances best for you and it's ready to go at a moment's notice.
I'll see if I can find a picture of what I'm talking about. Okay, if you look at these pictures, I think you can see the detachable base the locks into the head. Extra pieces are available or you could make one to fit.
