According to federal regulations, firearms can only be shipped to a licensed dealer. To avoid any delays in delivery, kindly ensure that your FFL (Federal Firearms License) dealer sends us a copy of their license, along with your name and order number via email. In case you don't have your FFL with you, we will get in touch with your dealer to obtain a copy. Once we receive the FFL, we will begin processing your order, and the lead time will start from that point. Please feel free to reach out to us at FFL@bushmaster.com if you have any queries or concerns regarding this proces.
Lower Receivers Shipments:
Lower receivers are also considered firearms under federal regulations and require an FFL (Federal Firearms License) prior to shipment.

We appreciate your attention to this matter as it helps us ensure a smooth and timely delivery of your order. If you have any questions or concerns about this process, please do not hesitate to contact us at FFL@bushmaster.com
