This is probably too old. There is another one, the Swedish CV90
105 variant. Using a GIAT 105mm smoothbore gun, mated to the CV90
body.

Now, there's an interesting comment made by TACIII in Strategypage,
which although is not the best authority around, does make for an
interesting read.
"The CV90 can keep up with the
Leo 2A5 as they go offroad and is intended for a higher intensity
of conflict. They are more expensive, though.
The Piranha IIIC and -H are excellent for peacekeeping or
patrolling as they are fast on roads and some offroad terrain,
they're cheap, upkeep is less than an IFV, less maintenace etc. So
a good vehicle for Iraq or Kosovo. The Swedes use the CV90 for
peacekeeping in places like Africa where the road network
sucks."

Furthermore, this guy posted
here that the Swiss Army had some problems with their Leos due
to the winding roads in the Swiss countryside. And that the
CV90-105/120 might make a better complementary option.
The dimensions of the CV series are not much bigger than our BX,
and I think it would be quite realistic to attempt to mate a 105mm
gun to the stretched BX version that took part in the US Army's
interim brigade combat vehicle tender, which the Stryker won.
We do have a lot of GIAT LG1s lying around..they're 105mms.
