Patent number: 8590201Abstract: An integrated grip and rail system is provided. Included is a firearm and the firearm grip. The grip is configured to be disposed in front of the magazine well and provide a stable grip point which does not allow a user's thumb or other appendage to be disposed between the grip and magazine well. The grip is configured so as to not interfere with the pivoting relationship between the weapon upper and weapon lower during partial or complete disassembly of the weapon. The rear region may also have a portion extending rearward along at least part of each side of the magazine well to form feed ramps as a part of the magazine well extension. Included is a magazine well extension mechanically coupled to a forearm rail system for mounting to the firearm.Type: GrantFiled: July 15, 2009Date of Patent: November 26, 2013Assignee: Grauer Systems, LLCInventor: John Brixius

Patent number: 7376615Abstract: A method and system is provided to automate many of the steps involved in processing restricted securities. Data can be received relating to restrictions associated with the trade of a security. Typically the data includes notification by a seller of their desire to transact a trade involving a restricted security as well as answers to a checklist of questions related to the restricted trade. In addition, the system can receive an electronic verification that the data is correct. The system can respond by automatically generating documentation supportive of the trade and receiving an electronic signature to execute the generated documents. Trade information can also be automatically forwarded to a clearing house. In addition, an instruction can be transmitted to a transfer agent to convert physical restricted securities into an electronic format. Notification that the securities have been converted can subsequently be received.Type: GrantFiled: December 29, 2000Date of Patent: May 20, 2008Assignee: Goldman Sachs & Co.Inventor: John Brixius
