FWIW, if you decide to try to share a bipod among rifles again, here's what I did...
Harris S-LM Bipod
ADM Picatinny Bipod Mount Adaptor
That gets the bipod set up (I also added a pod lock lever, but you don't NEED that). From there, I put a small picatinny section on my M-Lok rail on my AR (and also a picatinny section for rail on the Choate stock on my Savage 10 FCP, although that's not immediately pertinent). Finally, to allow it to be used on my Weatherby Vanguard I added one of these:
Swivel to Picatinny Adaptor
It's cheap and I wouldn't use it on magnum calibers or anything, but its fine for the .223 it's used on. There are slightly nicer options available though looks-wise I think the one above doesn't mess with the traditional silhouette as much which I prefer. Here are a couple:

You could also just modify your stock and install a picatinny rail directly to it too.
To me, doing it this way is a win-win. I don't have to deal with having a bipod (or having to take it off) on the rifle when I want to shoot off hand, but I can quickly toss it on there on any of them if I want to. And, I didn't have to justify spending $300-400 on bipods to the wife.
I'd have an adapter for my Savage Mark II as well, but for the moment I have a Caldwell XLA bipod on that full time since I never really shoot it off hand but I am toying with tossing a picatinny adapter on it just to have the flexibility.
Here are pics, the AR doesn't have it mounted but you can see the pic rail section for reference.
