ABSTRACT:
A firearm safety system includes a magazine block having a pair of opposed parallel shoulders slidably inserting beneath a pair of respective lips at an upper portion of a magazine and positionable in a loading chamber of a firearm to trap the charging handle to make it inoperable. Once the magazine block is positioned within the loading chamber, the firearm cannot operate because the magazine block inhibits ammo rounds from entering the loading chamber and prevents a spring-loaded bolt and firing pin from moving forward for propelling ammo rounds. The firearm safety system may operate in a stealthy mode by attaching the magazine block to a cover plate including a pair of resilient elements for locking to a female receptor notch of the magazine block thereby rendering the magazine block, loading chamber, ejection port and a portion of at least one loaded spare magazine hidden. To ensure a secure locked position, the cover plate cannot be unlocked from the magazine block until the magazine is pulled downwardly away from the loading chamber.
