CMMG is temporarily halting the sale of complete firearms, upper receiver groups, lower receiver groups, and Radial Delayed Blowback BCG kits on our website in order to focus on outstanding orders. We apologize for the inconvenience and appreciate your patience as we traverse this extremely busy time. Sign up for notifications on your favorite products to get notified when they become available again or find a local dealer on our dealer page.
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.
