Abstract
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.
