发明名称 Externally visible safety device for firearms
摘要 A safety device for use with a repeating firearm having a magazine well for holding a box-like removable magazine, to prevent the firearm from being unintentionally fired and for providing an indication visible at some distance that the firearm is in such a safe condition. A plug having a body whose dimensions correspond with those of a portion of a magazine for such a weapon includes flanges to close the magazine-receiving opening of the magazine well, a top portion which extends from the magazine well into the space which is occupied by the bolt of the weapon when the bolt is in a position closing the breech of the firing chamber of the weapon, and a member which holds a bolt latch in a position locking the bolt open. The body includes a detent for interacting with a magazine retention latch of the firearm to retain the safety device within the magazine well, with a portion of the device being visible externally as an indication that the safety device is operatively installed in the weapon. Visible exposure of more than a predetermined portion of the safety device provides an indication that the safety device is not properly installed in the weapon and that the weapon is not in a safe condition.
