From the bill:
This bill would, commencing July 1, 2013, and with certain
exceptions, prohibit any person from importing, making, selling,
loaning, transferring, or possessing any conversion kit, as defined,
designed solely and exclusively to convert certain
firearms with a fixed magazine into firearms with the capacity to
accept a detachable magazine and other features making the firearm an
assault weapon and would make violations subject to criminal
penalties.
From the ILA article:
SB 249, as amended, would make a small but profound change to the definition of what constitutes a detachable magazine for a semiautomatic firearm. By doing so, hundreds of thousands of semi-automatic rifles, which were legally sold in California over the last decade, would become illegal on July 1, 2013.
Am I missing something here? What rifles that are now legal would become illegal?
