“If you really want to boil it down, the laws the Legislature passed didn’t authorize the Department of Justice to do what it did,” said Brandon Combs, a spokesman for the Calguns Foundation.

The California Department of Justice Bureau of Firearms website has a clock ticking down to the deadline for assault weapons owners in California to register their firearms.

Gun owners have until June 30 to register their assault weapons. But four gun rights groups hope to stop the clock and have it reset.

To do that, the groups filed a lawsuit last week in Riverside County Superior Court challenging the regulations, claiming the Department of Justice did not go through the proper regulatory process after the gun laws were passed last year.

“If you really want to boil it down, the laws the Legislature passed didn’t authorize the Department of Justice to do what it did,” said Brandon Combs, a spokesman for the Calguns Foundation.

What the state did, through SB880, was add numerous new characteristics to what is considered an assault weapon in California, creating a whole new group of assault weapons.

People who have firearms that fit the new definition of what is an assault weapon are required to register them by June 30.

Some of the most controversial features of the law include listing as assault weapons semiautomatic rifles and pistols with detachable magazines.

The law, signed by Gov. Jerry Brown in 2016, also outlaws any gun that can carry more than 10 rounds in a nondetachable magazine.
