Which English-speaking country has the most liberal gun laws?

I have recently asked how to get an assault rifle, but the only country I can ever find is USA. I want to find out which English-speaking country that has the most liberal gun laws, especially one that will allow assault rifles. I want to move out of Australia to find a country that has the most liberal gun laws.

My criteria I am looking for is:
-Country other than USA(because getting a citizenship is hard there)
-English-Speaking or a country that has most of it’s citizens speaking German or English
-Allows assault rifles(optional)
-Allows at least military caliber rifles
-Not somewhere in the Middle East or a politically-unstable country
