The first few attachements I unlocked had their corresponding assessments unlocked too, but this haven't happened with the last 4 or so of the attachements I've unlocked (suppressor, hologram, shotgun, gauss) For a while I wondered if these assessments had some rank requirement too, but that sounds strange. Anyone else have this problem? I've used the suppressor on the sniper rifle for a long time, and it's a bit annoying to not get the extra xp for it.
