Federal law requires that you be 21 years of age or older to purchase a pistol, 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 are still “firearms” by definition and are subject to the same GCA limitations as any other firearm. 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.
