UK OOB Hughes Chain Gun Queston

Apparently the Warrior's CG has been chaged class to fit that of the Rarden gun (class 19), which means that both should be able to fire at low-flying aircrafts (any hard data about it?), and anyway if one can, the other should be able too, as being coaxial.

Now about the HEK, I just checked and both have a HEK=5.
Are you sure you have the latest version? I've checked the 2.0 update I think, so possibly what you point out was a mistake that has been corrected since.
Otherwise, maybe that's something about the use (shorter or longer bursts) made of it in different classes fo vehicles.
