So the issue is private sales. Say I own a gun that I purchased years ago from a store and now I want to sell it to my buddy. Under (my understanding of the) current law as a private citizen I can just sell it to him without a NICS (national instant criminal background check) check. As it stands now I need to be an FFL (federally licensed firearms dealer) in order to call or access the system.
Personally, I see no issue in expanding NICS to private sales so long as we expand the capacity of NICS to ensure private citizens can call and get checks done in an expeditious fashion. In the last few weeks NICS was flooded with calls due to elevated gun sales and some folks were waiting upwards on an hour on hold for NICS.
I am also all for NICS improvements such as ensuring states are providing more complete data on felony convictions and mental health data. In fact the NRA has backed many NICS improvement bills in recent years to expand capacity.
