Because 80% Lowers are not considered firearms by the ATF, we can ship them right to your front door with no FFL required... but finished rifles must meet all applicable laws and you must be able to legally own a firearm. Compliance with all laws is YOUR responsibility. All sales are subject to our Returns and Cancellation Policy.
