DERP any law contrary to the Constitution is null and void Mulberry vs Madison

The supreme court U.S. vs Miller 1939 ruled that in order for a firearm to be protected by the second amendment, it must have some reasonable relationship to the preservation or efficiency of a well-regulated militia, in common use of the time, and supplied by the citizen.
So tell me what firearm is there that is in common use that would have some reasonable relationship to the preservation or efficiency of a well-regulated militia?
The second amendment states
A well-regulated militia being necessary to the security of a free State, the right of the People to keep and bear arms shall not be infringed.
The 14th amendment says laws must be equal
Amendment XIV
Section 1.
All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the state wherein they reside. No state shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any state deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws.
You are done.
