CMMG is a build to order company. We appreciate your patience as we traverse this extremely busy time. We currently do not have estimated lead times with long backorder list and high demand. Orders are processed by date received and as parts and components become available to complete the build.
THIS PRODUCT IS BACKED BY THE CMMG LIFETIME QUALITY GUARANTEE.
