Article VI know what the Second Amendment is for. I've had to study it quite extensively in getting my degree in criminal justice, but the Constitution was also written to be amended to meet the change in technology throughout time. The Constitution doesn't say you can't have a tank or a bazooka, do you think people should be allowed to have those too? Like military assault rifles?
Where does it say that constitution was written to be amended to meet technological change?
Nope, it say when and how can be changed. Nothing about meeting technological changes.
The Congress, whenever two thirds of both Houses shall deem it necessary, shall propose Amendments to this Constitution, or, on the Application of the Legislatures of two thirds of the several States, shall call a Convention for proposing Amendments, which, in either Case, shall be valid to all Intents and Purposes, as Part of this Constitution, when ratified by the Legislatures of three fourths of the several States, or by Conventions in three fourths thereof, as the one or the other Mode of Ratification may be proposed by the Congress; Provided that no Amendment which may be made prior to the Year One thousand eight hundred and eight shall in any Manner affect the first and fourth Clauses in the Ninth Section of the first Article; and that no State, without its Consent, shall be deprived of its equal Suffrage in the Senate.
