There seems to be a hybrid being set up by the right wing. The individual rights found in the 2d Amendment were attributed to the introductory clause (well regulated militia) having no effect on the operative clause (right to keep and bear arms). However, the Constitution and subsequent acts, etc., gives the Fed and State the ability to designate the militia, arm them, and the President the power to call them up. Modernly, the militia is now the National Guard and a small navy. The draft pool of able bodied men is called the unorganized militia.

To justify owning any weapon and the Fed to be limited in this area, court cases from prior to Heller reasoned they were necessary for the militia. You'll find court cases reasoning that this weapon would be necessary for the militia, so individuals can own it. So we're looking at a hybridization to get individual rights independent of the militia, and types of weaponry allowed based on the militia.

These look like conflicting views that will be reconciled with difficulty, but have faith in MAGA, they can do it and insist on it.
