There are 3 types of police hunters, AR, Command, and NCA and decrease in price (generally) in that order, they all have seperate skins. You can get a normal green hunter from somebody who has viper but It's better to get an ifrit since they're 100x better in combat and it'll work out cheaper.
honestly idec about the skin anymore Lmao, just want a hunter to stick in my garage. Aint rich so dont wanna pay stupid money like 5mil. Current lowest i've been offered is 1.7mil. Still looking tho, lower is always better
