Quick addition: 40 KRKK 2005 (40mm AGL) can be installed on the same vehicle platform as 12.7 mm AAMG.
40 KRKK 2005 on mil.fi
"Voidaan käyttää sekä ajoneuvon kehälavetilta että tukikohtajalustalla" = "May be operated both on a vehicle platform and on a tripod"
That said, on XA-180/185 APCs the AGL is definitely an option and I suspect it is also the case on XA-203s as the AAMG uses a custom mount adapter to fit to Norwegian (NATO?) standard mount. (I operated 12.7mm AAMG on XA-180 as well as in terrain in FDF in 1999)
