The fourth amendment addresses personal effects; and weapons are certainly effects that are personal for private protection of life, liberty, and that as property, as well as other effects and property
In addition to “persons, houses, [and] papers,” the Constitution protects individuals against unreasonable searches and seizures of “effects.”
If your neighbor owns a weapon, be it a pencil, a pair of scissors, a kitchen butcher knife, or be it as it may, a gun ; this is none of your business; especially if you're coveting her or his possessions.
Your fear is merely respect
