but hopefully some info can be found that proves otherwise :P

I don't know if this graph can show that it can point lower, it definitely looks more than -2°.Image from  Новейшие китайские зенитки PGZ-07 поступают в войска — Военный информатор (military-informant.com)

bro why is it that the pgz09 has less ammo then both gepard and type 87? its based of the gepard and from sauces it says the pgz09 had around 2,000 ammo but for balancing reasons i can say its fine but that fact that it has less ammo then both gepard and type 87
