A device to disqualify a gun as an assault rifle by removing one of the six “evil features” of the Assault Weapon Ban (AWB) 1994-2004 (See Evil Features), the detachable magazine. The definition of a detachable magazine is one that can be inserted and removed by hand. The bullet button is a device that must be engaged to insert the magazine that cannot be operated by hand. It requires a simple tool such as a bullet to depress. While satisfying the requirements of the AWB, the bullet button, with its ease of use, has been regarded as a legal loophole for assault rifles, and the device is currently banned in California.
