One Word Picatinny Rail (ya i know two words). Put Pic rails on all your rifles. You can then switch your scope to any rifle re zero and your off to the races. You can pick any scope with adjustable turrets. I would recommend a mount like a SPHUR. They are expensive but they keep your original zero. Then you just count clicks to change between firearms and theoretically you just dial it back when you switch to the original firearm.
Here is a company in Canada that sells them. They arent cheap. But I would rather spend 4-5K on a great scope and use it on all my rifles then spending $1500 on 4 or 5 scopes for several rifles
