Here is the problem.I will NOT regester my guns
If a person purchases a new gun from a dealer then in a roundabout way they are registered.
Your name, address, DOB, and social security number (if a person list it) plus the make, model, serial number and caliber of the gun are all put on paper and saved.
One of the reasons to not buy from a FFL dealer. All the government needs to do is place that information in a database.
The current administration would like to place a burden on the citizens by mandating that all gun sales be made through a FFL person. This way they will have their federal registration of the guns.
