In one aspect, a method provides a reciprocating bolt by a bolt assembly having a bolt assembly body, a cap affixed to the bolt assembly body, and a base affixed to the bolt assembly body opposite the cap. The method includes biasing a bolt carrier in the bolt assembly body in a retracted position relative to the bolt assembly, resulting in a center portion of a diaphragm disposed between the cap and the bolt assembly body being deflected toward the cap. The method also includes applying an actuation force to the bolt carrier so as to move the bolt carrier from the retracted position to an extended position relative to the bolt assembly by oppositely deflecting the center portion of the diaphragm toward the base, and discontinuing the applying of the actuation force while the bolt carrier is in the extended position. |
