CMMG is aware of the recent Ninth Circuit ruling regarding magazine capacities in the state of California. At this time, we are taking orders on high-capacity magazines and putting them on a temporary hold while we gather more information. We will fulfill these orders as soon as we can confirm that we are legally able to do so. In the meantime, we appreciate your patience.
