  • Patent number: 8590201
    Abstract: 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.

  • Publication number: 20100326266
    Abstract: A firearm barrel assembly having a gun barrel with a muzzle opening on a distal end, a shroud coaxially surrounding at least a portion of the barrel, the shroud having a distal portion extending beyond the muzzle opening defining a shroud front region having a distal end portion, a proximal portion extending proximally from the muzzle opening defining an annular region between the barrel and shroud, the shroud front region and annular region in fluid communication with substantially no obstruction between the shroud front region and the annular region, and a front wall disposed at the distal end portion of the shroud. The wall has an opening to allow passage of a projectile fired from the firearm.

  • Patent number: 7376615
    Abstract: 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.
