A firearm accessory mounting rail with an integrated back up sight system including an elongated Picatinny rail having longitudinally spaced apart first and second end regions and a transverse profile. A first sight element has a visual marker substantially centrally positioned. A second sight element has laterally spaced apart visual markers. A substantially centered longitudinal channel extends along the upper surface of the rail between the first and second sight elements. The firearm may be sighted by visually aligning the marker of the first sight element between the markers of the second sight element, the visual alignment being at least partially through the longitudinal channel. The sight elements may be defined completely within the transverse profile of the rail so as not to interfere with the normal attachment of any accessories to the rail and may be adjustable for windage and/or elevation. The visual markers may be illuminated by light gathering fiber optic or tritium elements.       Recently Added Patents Communication devices and methods for providing services to communication devices in a communication system including a private cell Driving apparatus Integrated circuit packaging system with filled vias and method of manufacture thereof Wound and mucous membrane disinfectant System and method for recording vehicle events and for generating reports corresponding to the recorded vehicle events based on driver status Portion of a display with a graphical user interface Aggregating compositions, modified particulate metal-oxides, modified formation surfaces, and methods for making and using same   Randomly Featured Patents Structure to support, display and illuminate a baseball cap Therapeutics for thrombocytopenia Active seismic monitoring of fracturing operations Thermal probe and apparatus incorporating the same Method and arrangement for monitoring an administration of at least one medication Portable blind Micromachined bilayer unit for filtration of small molecules Beverage bottle MOS transistor and method for forming the same Wood glue © 2006-2008 PatentGenius.
