My local FFL says the 4473 is going to an online database. The paper forms will be gone. No more requirement for an FFL to keep them on file. The BATFE has always had the ability to collect the 4473 forms from an FFL.
My FFL is frankly happy to be rid of the responsibility of keeping the paper on file. The downside is the obvious creation of an online database of firearms purchases.
The bill the NRA appears to be citing would require a federal LICENSE to possess any firearm with a removable magazine. That is a blatant infringement on the right to keep and bear arms. It converts an unalienable right into a licensed privilege. That is unconstitutional.
That sucks swampwater ...
