If you are looking for budget KAC PDW magazines, you can get some ACM made ones at RSOV.com which come in lots of 2 per purchase. We don't know if these can feed well inside VFC KAC PDWs, or perhaps for the ACM KAC PDW which should have been released by this month. These are mid-cap magazines so they can have either around 80 or 120 rounds. Reasonably priced at US$11.69, shipping costs not included yet.
