Patent number: 8448363Abstract: A system allowing either right or left-side (ambidextrous) ejection of a shell from a weapon is provided. The system may comprise a bolt receiver having left and right-side ejection ports; a firing bolt assembly having left and right-side alignment slots and an extractor claw; and a relocatable ejection port cover assembly disposed alternatively in either the right or left-side ejection port to eject a shell from the opposite open ejection port. The ejection ports and the cover assembly may be formed having bilateral symmetry to facilitate relocation of the cover assembly from one side to the other. The cover assembly comprises a mounting flange, an ejection port plug disposed within either of the ejection ports, and a rail configured for being disposed within the alignment slots and including an extended portion and a contact face that engages the shell so that it is ejected from the open ejection port.Type: GrantFiled: February 8, 2011Date of Patent: May 28, 2013Inventors: Thomas Angelo Fargnoli, Miranda Allison Bernabei, Ronald Herman Kohlstaedt
