FFL Terms and Conditions

– Any items placed on the same order as a controlled item will also be shipped to the FFL. If you would like additional items shipped to you directly, please place them on a separate order.

– Review our FFL Ordering Instructions HERE before placing your order.  (Opens new window)

– Prices do not include your dealer’s transfer fees.

There will be a 30% restocking fee on all controlled items 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.
