There are some in stock everywhere they sell out fast though, Friday i finally got my Zastava zpap ordered from Primary arms it took a lot notify me when available and seeing it sold out before I had a chance, but most AKS are imported so it is more difficult to get in large quantities, the there is a fear that the next president is going to ban the import of aks so there is still some panick buying.

Robert, AK's were not as plentiful as AR's to start with. With the start of the pandemic, imports were severely curtailed as well which also is having an affect of a slower recovery of AK's as opposed to the more numerable AR's. Cheers and stay safe!
