Further restrictions on Second Amendment rights in California have resulted in a flurry of assault weapons registrations, the Los Angeles Times reports.

Since the passage of a bill that expanded gun registry in the state, 43 percent more assault weapons have been registered in the last 11 months. That amounts to over 68,000 applications.

The enhanced registry was passed in 2016 after the San Bernardino shooting of the previous year. It outlawed the sale of semi-automatic assault rifles that allow a “bullet button” to quickly dispense with expended magazines and attach fresh ammunition. Gun owners who already owned this product had to have it registered with the state’s justice department as of June 30 this year.

California targeted the rifles after the San Bernardino shooting, as well as an earlier incident at the LA airport that killed a TSA agent.
