Patent number: 6701659Abstract: A cartridge containment device and method is designed to contain or catch unfired cartridges ejected from an automatic or semi-automatic firearm during unloading. To accomplish this, a cartridge containment box having an open top and otherwise configured with the general external configuration of a standard cartridge magazine is inserted into the firearm in place of the cartridge magazine. A blocking plate is attached to the cartridge containment box; and when the box is inserted into the firearm, the blocking plate is located adjacent the ejection port of the firearm, and prevents cartridges from being expelled therefrom. The cartridges then drop into the containment box for removal from the firearm.Type: GrantFiled: February 4, 2003Date of Patent: March 9, 2004Inventor: F. Richard Langner

Patent number: 6698126Abstract: A firearm safety bullet that locks into place rendering the gun inoperable. When fired the propellant forces a ram into an internal captive plastic sleeve. The shaft of the ram which has a tapered end, pushes its way through the center of a captive plastic sleeve expanding it with a pneumatic force causing the plastic sleeve to be pushed hard against the inside of the firearm and locking the shell inside the firing chamber. This will do several things all at one time, it will lock the shell inside the gun rendering it unusable, it will prevent a live shell from being introduced and it will stop anyone from using the firearm that is not aware that a safety bullet has been placed in the gun. It will save lives and prevent injury from accidental shootings.Type: GrantFiled: May 30, 2002Date of Patent: March 2, 2004Inventor: F. Michael Worley

Patent number: 6679158Abstract: The present invention provides a powered aiming platform for pointing devices such as firearms, illumination devices, or sensing instruments, remotely controlled by a hand-controller device, with video feedback of the aiming position and audio feedback of the exact direction and speed of positioning movements. The present invention overcomes the safety and accuracy limitations of manual and conventional remotely-controlled aiming mechanisms, thereby allowing operators to point devices accurately and quickly with predictable, precise control. In the case of firearms, the present invention maintains a steady position after repeated firing.Type: GrantFiled: May 18, 2001Date of Patent: January 20, 2004Assignee: Precision Remotes, Inc.Inventors: Graham S. Hawkes, Howard F. Konvalin

Patent number: 6622415Abstract: An adjustable sight assembly for attachment to a firearm is provided. A base with a recessed portion has a plate that loosely fits within the recessed portion. A windage adjustment assembly cooperating with the base and a first end of the plate i) effects side-to-side movement of the plate within the recessed portion of the base, and ii) defines a pivotal coupling of the plate to the base at the first end thereof. A second end of the plate moves along an arc when the plate is pivoted about the first end thereof. An elevation adjustment assembly cooperating with the base and the second end of the plate effects elevation of the plate's second end. A sight is pivotally coupled to the plate such that the sight can lie against the plate when not in use and can be rotated approximately 90° to extend vertically from the plate when in use.Type: GrantFiled: July 19, 2002Date of Patent: September 23, 2003Assignee: The United States of America as represented by the Secretary of the NavyInventors: Michael M. Canaday, Mark R. Whalen

Patent number: 6606811Abstract: Detachable ammunition magazines for firearms, particularly conversions of M16/M4 series rifles to utilize AK47 magazines, are provided with improved bolt catch actuators. These new bolt catch actuators have an elliptical opening though the upper end of the proximal wall that extends into the rectangular cross-section passage within the firearm magazine. A wire spring defined by an upper free-end and a lower fixed-end is cantilevered by its fixed-end to the right side plate of the magazine follower for movement with the follower in a manner that enables the free-end of such wire spring to project through the opening when the follower reaches its apogee. As the wire's free-end passes through the opening it engages the bolt catch of the firearm causing the bolt to be retained in its open position after all the ammunition in the magazine has been fired.Type: GrantFiled: October 9, 2002Date of Patent: August 19, 2003Assignee: Knight Armament CompanyInventor: Douglas D.
