bat model M ???

I cant seem to find this info so I was hoping someone here might know.
Is the bolt on a model M bat the same size bolt that a Model B has? In other words, will a model B bat bolt fit into a model M action? thanks Lee

They vary in length and I'm pretty sure diameter as the M will take up to Lapua size cartridges.

M is .935 longer than B.
MB is the same bolt length as B
