Abstract: A bullet-resistant garage door is formed with multiple garage door panels spaced vertically and pivotable relative to one another to permit conventional opening of the garage door. Each garage door panel is formed with an interior ballistic panel, an exterior ballistic panel and an insulation panel positioned between the interior and exterior ballistic panels. A ballistic shield is attached to the exterior ballistic panel to overlap the gap between the exterior ballistic panels of adjacent garage door panels. The exterior ballistic panel is operable to allow the penetration of a bullet of a given caliber while dissipating the energy of the bullet so that the bullet will not penetrate the interior ballistic panel and become trapped in the insulation panel. Sheeting and trim members can be attached to the exterior ballistic panel and the shield to provide an aesthetically pleasing appearance for the garage door panels while maintaining bullet-resistant characteristics.

Abstract: A method for making an improved projectile 360, 460 by defining a discontinuity, groove or trough in a distal ogive section of the projectile to provide an external ballistic. effect uniforming surface feature (e.g., nose ring groove 369, 469) which makes an unsupported gap in the ogive profile that beneficially affects the flow of air over the front half of the ogive. The improved bullet's external surface discontinuity feature (369 or 469) creates effects in the flowfield that dominate any dynamic effects from bullet-to bullet manufacturing inconsistency and resultant differences in dynamic behavior.

Abstract: An aiming apparatus for a firearm has a frame, a plurality of visible and/or invisible light generators connected to the frame, with each light generator operable to propagate planar and/or non-planar light in the forward direction. Each light generator utilizes shaping optics to create straight or curved lines of light. Straight lines of light propagating in a forward direction will create a plane of light, while curved lines of light propagating in a forward direction will create non-planar light. A plurality of planar light oriented in a non-parallel, overlapping relationship creates a straight intersection line of light, while a plurality of non-planar light orientated in a non-parallel, overlapping relationship creates a straight or curved intersection line of light. When projected against a target surface, a plurality of planar lights creates a projected cross shape, which may have an intersection point.

In the open position of the check valve, the check valve is configured to permit entry of a gunfire pressure, created in a barrel of a gun from which the extended range projectile is configured to be projected, into the pusher plate assembly such that, when the extended range projectile exits the barrel, the gunfire pressure moves the center projectile body from the stowed position to the deployed position and propels the extended range projectile.

Abstract: The invention relates to an electronic device that is used to block the accessibility of a firearms Trigger. Wherein an electronic device is mounted on a rail or rail accessory and is locked in place using security screws and tamper proof fasteners allowing the device to fit an array of single action and striker-fired handguns. The security screws are in place to stop easy removal unless the possessor has the proper tool to remove them. The device its self uses a battery to operate and picks up a transmission broadcasted from a Bluetooth within its programmed range by the use of a Bluetooth proximity detector. Once the transmission has been picked up it activates its locking mechanism in the form of a solenoid causing its pin to lift and allows a slide placed In front of the trigger acting as a second trigger to move back and forth allowing the movement of the firearms trigger. The slide is moved back its original position by the use of a spring.
