摘要： PURPOSE:To remarkably enhance sport shooting performance with safety by magnetically attracting a bullet to be fed to a bullet holding magnet of a gas jet port, and to discharging the bullet to a bullet magazine by upward returning move of a bullet feeder/discharger. CONSTITUTION:When a bullet placing surface provided on the upper end of a bullet feeder/discharger 10 moving down at the time of operating a trigger 6 is moved from a feed port 17a of a bullet magazine 17 placed oppositely above to a gas jet port 9, and returned to its original state after the trigger 6 is operated, it is raised to the original position, and returned. Then, a feeding magnet is arranged on the pullet placing surface, a head bullet 11 is placed one by one on the magazine 17, and fed to the port 9 by moving down it. Further, a bullet holding magnet is arranged in the port 9, the bullet 11 to be fed is magnetically attracted to the port 9, the port 9 is closed by its holding force to enhance a shooting gas pressure, and the pullet 11 is discharged from the port 9 to the magazine 17 by the upward resetting move of the pullet feeder/ discharger 10.

摘要： An apparatus and method for creating the apparatus that holds a bolt open after a last round is fired from a magazine is disclosed. A lower receiver may include at least two cavities. A transfer bar may be configured to fit into a first cavity of the at least two cavities. A hold down may be configured to fit into a second cavity of the at least two cavities. At least a portion of the hold down may be configured to overlap with at least a portion of the transfer bar to hold the transfer bar in place. The transfer bar, when a final round is fired from a magazine in the lower receiver, may be pushed up by a bump in the magazine to transfer upward movement to the transfer bar that catches a bolt and holds the bolt open until activation of a release button.
