Every gun sold should require a background check, period.
In 1999, the NRA leadership in Washington, pretty much the same people intact, were for (expanded background checks.)
I don't believe anybody has a right to own any kind of a firearm.
I believe in order to obtain a permit to own a firearm, that person should undergo an exhaustive criminal background check. In addition, an applicant should give up his right to privacy and submit his medical records for review to see if the person has ever had a problem with alcohol, drugs or mental illness... The Constitution doesn't count!
