Never heard of a “police kit”. I’m sure Hungarian LE has AKs but I imagine they would either be some kinds of identification or none at all. Meaning, they would be no different from other Hungarian AKs.
Also, that “semi auto” trigger group is in fact a full auto trigger group without the auto sear. If he is trying to get more $$ with claiming a “police kit” then he’s not smart enough to pull the auto trigger springs from the kit.
I will say that is a beautiful kit though. Ask him why he thinks that is a “police kit”.
