This law applies to all firearms regardless of their origin, including handguns, rifles, and shotguns. It also applies to any parts or components of a firearm, such as ammunition, silencers, and barrel shrouds. Under 18 U.S.C.

The penalties for violating 18 U.S.C. Sec. 922(j) can include up to 10 years in prison, a fine of up to $250,000, or both.
