20110139031 | CONNECTION MECHANISM AND METHODS FOR CONVERTIBLE RAILWAY-ROADWAY SYSTEMS - Devices, systems, and methods for connecting a rail bogie to a bimodal hauling vehicle and converting the vehicle for use over either a railway or roadway are disclosed. An illustrative system for connecting a rail bogie to a bimodal hauling vehicle includes a receiver unit coupled to the vehicle. A king pin and bogie locking mechanism on the receiver unit can be used to releasably secure the rail bogie to the receiver unit during transitioning of the vehicle from a highway mode of operation to a railway mode of operation. The bogie locking mechanism can include a number of lock jaw members and a lock jaw actuator, which can be engaged to actuate the lock jaw members between an unlocked position and a locked position about a number of locking pins on the rail bogie frame. | 06-16-2011 |

20110271827 | Firearm Having Gas Piston System - A firearm having a gas piston system includes a bolt carrier, an adjustable gas piston block located forward on the firearm and an over-the-barrel spring and guide rod arrangement, all of which is housed and contained in a top rail that runs the length of the firearm and that maintains the alignment of these firearm components. The firearm also includes an ambidextrous, non-reciprocating charging handle located forward on the firearm and positioned within the top rail for charging the firearm. | 11-10-2011 |
20140013642 | HANDGUARD FOR FIREARM - A handguard or other cover for a firearm includes a shell or body with a hollow interior cavity and a retaining structure configured to engage the forearm and retain the shell in place on the forearm, where the retaining structure is releasable to permit removal of the shell from the forearm. The shell extends between first and second edges around an angular range greater than 180° and less than 360° to define the shell in a semi-tubular shape or a C-shape. The shell may have a concave inner surface and a convex outer surface extending between the first and second edges. The first edge is spaced from the second edge to define a gap providing access to the interior cavity, and the shell is configured to be connected to a forearm for the firearm by inserting the forearm within the interior cavity. | 01-16-2014 |
20140075814 | Firearm - A firearm having a gas piston system includes a bolt carrier, an adjustable gas piston block located forward on the firearm and an over-the-barrel spring and guide rod arrangement, all of which is housed and contained in a top rail that runs the length of the firearm and that maintains the alignment of these firearm components. The firearm further includes components that provide full auto firing capability. These components include a specially designed auto bracket that cooperates with a modified bolt carrier and a modified upper receiver. | 03-20-2014 |
20140075816 | FIREARM HAVING GAS PISTON SYSTEM - A firearm having a gas piston system includes a bolt carrier, an adjustable gas piston block located forward on the firearm and an over-the-barrel spring and guide rod arrangement, all of which is housed and contained in a top rail that runs the length of the firearm and that maintains the alignment of these firearm components. The firearm also includes an ambidextrous, non-reciprocating charging handle located forward on the firearm and positioned within the top rail for charging the firearm. | 03-20-2014 |
