Thank you for both suggestions, although I'm certainly going with the VCI Paper and Impervious Bag strategy. It's easier and less expensive than what I had in mind. To leave the scope mounted I would need to use 6" PVC and that is significantly more expensive than the paper/plastic solution. In addition, it does exactly what I want; that is, take the gun out and shoot it - not spending a good share of the time I have just getting it ready to shoot.
I am so glad that I asked.
