how hard is it to make an arms license?

[Zyzz]

I was looking up for gun stores online in Pakistan after watching the Vice News talking about Darra adam khel and i stumbled upon one shop(Peshawar city) that had like golden AK-47 & Glock etc and i asked him if i could test fire it and he told me to get an arms license first or he won't allow me to do it.

Lol so how hard/how long would it take to get an arms license?
What are the requirements. I am an overseas pakistani btw.
