where have you seen that?
if the firearm was made in America
it has a tracking history
all the feds has to do is determine the maker
call them and give them the serial number
the maker then will tell them who they first sent it to
and from the dealers use a 4473 form

and then as soon as it's a private sale what happens?
they have copies all the way to the last person
ask them or charge them with a crime
if they gave or sold the firearm to someone that should not have had it
private sellers do not have to maintain records
So.....you simply arrest the criminal who has possession of the gun...or you arrest him when he uses the gun to commit a crime. A private seller is not a police officer...it is not his job or his duty to conduct a background check on a private sale.
Background checks for private sales are simply the excuse to get gun registration...since that is the only way to check to make sure a background check was done...
And it is also a lie.....the anti gun leadership has quietly changed terms.....you nutters think they want all gun "Sales" to undergo a background check.....the anti gun leadership wants all gun "Transfers" to under go a background check...big f*****g difference.
That would mean the end of private firearm instruction outside of a large corporate gun store...it would mean you could not loan a gun to a friend at a range, or to your wife if she is going out shopping...without a criminal background check....among other vile things that it does....and it turns normal, law abiding gun owners into felons and destroys their lives....
Which is the whole point to universal background checks.
