I replaced all 4 weapon slots with microdrivers.
I cannot buy ammunition for slots 3 and 4.
I got enough money and still got upgrade space, and was able to buy for slots 1 and 2.
I am also able to sell a 1000 bullets from slot 4, but slot 4 still doesn't highlight.
I am able to sell microdriver 4 and when I buy it again it has more ammo, 5000 to be exact, so that would be a workaround.

Looks like the mount has less volume than ammo volume of the weapon installed in it. You can get it there in the first place because at this time volume is not checked - exclusion supposed to be used for missiles on external mounts.
Got to fix logic here, yeah.
