Availability of this item is subject to applicable federal, state, and local laws and regulations. Always have full knowledge of your state and local gun laws before attempting to order or purchase a gun.

If you have any questions we are happy to assist you. Any orders returned due to legal restrictions or failed background checks are subject to a 15% restocking fee and shipping charges.

This rifle is not available in CA, HI, NY, NJ, MD, & MA due to local state guns laws.

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.

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.

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.
