Yes homemade guns should be subject
to inspection until our Congress can legislate Laws to ban/remove these guns from private ownership. Guns are lethal weapons they should be regulated just like we regulate automobiles, motorcycles,trucks, etc. They require owners to register them, insure them and submit them for regular inspections to provide certain protections for society and the ability to hold the owner accountable for misuse of the vehicle and to allow a system of monitoring the location and how the vehicle is being used.
These measures don’t violate the 2nd Amendment. They do provide a path to measures that reduce gun violence, verify ownership and manage problems related to guns being in the possession of people who have a history of violence or mental health
