The CA Legal Magazine Button is a product that allows the shooter to drop a magazine with the use of a tool. It prevents finger manipulation of the mag release, and creates a condition allowable under current individual interpretations of California law.
This does not create a detachable mag situation, but creates an attachable-fixed magazine condition. A bullet tip can be used as the tool, as can any small object such as Allen wrench, or small screwdriver.
This button can not be used with magazines greater than 10 rounds in capacity. To do so in the state of California on an unregistered assault weapon, would be a felony.
The CA Legal Magazine Button installs in less than a minute, requires no gunsmithing, or cutting on any part of the rifle. The installation is not permanent, and can be reversed just as quickly.
