With Scalia's written verbiage in Heller that he and the majority believe the States still have the right to regulate open carry and concealed carry, it is intuitive that the States also have the right whether or not to register and track ownership.
Ergo, this treaty, even if ratified by the Senate, which is highly unlikely for 2/3rd's (since Demo's barely have a majority alone), as Widge said, would be ruled unconstitutional by the present US Supreme Court if it were to be used by the White House to force the States to do anything.
Comrades, I already live in the CCP of Kaliforniya, and here they register and track. That's not a big problem, unless some wacko mayor like Nagin in New Orleans tries to go around and round up guns again.
The bigger problem is when jurisdictions like DC, Chicago, and California de facto administratively prevent your personal carrying of your defense firearm on your person legally. That's what I wish the NRA would attack in the US Supreme Court about.
Not sure what the NRA is waiting for
