FFL Terms and Conditions
Lower Receivers are an FFL item and must be shipped to an FFL. It must be purchased separately from any other items. Please enter your information or the receiving party's (the person that will be picking it up) information under "Recipient Name" while checking out. To expedite your order, please have your dealer email their FFL to us. If the dealer you are using to transfer a firearm has not sent us a currently updated FFL to put on file, there will be an extended period of time needed to process your order.
Email: info@moriartiarmaments.com

There will be a 30% restocking fee on all lower receivers returned because of failed background checks.
Federal law requires that you be 21 years or age or older to purchase a stripped receiver or frame. If a frame or receiver can only be made into a long gun (rifle or shotgun), it is still a frame or receiver not a handgun or long gun. However, they still are "firearms" by definition, and subject to the same GCA limitations as any other firearms. See Section 921(a)(3)(b). 18 U.S.C. Section 922(b)(1) makes it unlawful for a licensee to sell any firearm other than a shotgun or rifle to any person under the age of 21.
