Is it worth more, short answer no.. a Zastava is just a Yugoslavian/Serbian made weapon, made pretty much in the same factory as the Mausers, Aks, Tokarevs and even commercial variants.. Now you say just a Yugo, is it an M59, a M59/66, a M59/66A1.. a typical M59 will carry a small premium over a model with a launcher. Where I am, a typical price for the launcher model is usually between 4 to 500 depending on condition, a primo Cherrys import will be on the higher end.
