Are APA and Hawkins DBMs interchangeable?

I’ve found conflicting info on whether they are standard M5 footprint (APA)

I’m guessing MCMillan factory inletting for these 2, as well as any M5 are the same?

Just making sure, as I don’t want to have to do any extra inletting if I buy a stock that was ordered for Hawkins and I intend to use APA.

Thanks
