Abstract: A bullet has a cylindrical body portion and a conical tip monolithically formed with the body portion. The bullet is hollowed out to form an internal cavity. A sidewall defines the structure of the body portion and the conical tip. Bullet structure provides for a bore size, low weight, high velocity, and low recoil projectile having a full-bore size that does not have to expand to a larger diameter during firing in order to transfer its energy to a larger wound channel. In one embodiment, a plurality of recesses is provided on the body portion and extends through the sidewall. The recesses are disposed circumferentially in the radial direction and are offset longitudinally along a longitudinal axis of the bullet. The internal cavity includes a plurality of trusses extending in a radial direction. Instead of or in addition to, the trusses, the wall of the internal cavity may include one or more ridges.

Abstract: The embodiments of the disclosed invention relate to fiber optic weapon sights that use a reflector to direct ambient light to a fiber optic rod, and thus can provide weapon sights that are bright, or at least visible, in a variety of lighting condition. In one instance, the reflector can have a concave shape, such as a spherical or parabolic shape, that can focus ambient light on the fiber optic rod and thereby significantly increase the brightness of the weapon sight. The embodiments of the present invention can accordingly provide enhanced fiber optic front and/or rear sights for weapons including rifles, pistols, and shotguns.

The invention further includes a regulator occupying a portion of the chamber to define a chamber operating volume, the regulator having at least one outer diameter corresponding to an inner diameter of the passage to substantially inhibit gas flow from the pass through the second opening.

Abstract: A compact silencer device for a firearm comprising of multiple chambers which trap the gases from a projectile exiting the barrel of a gun to slow down the gases and reduce the temperature, sound, and flash associated with the projectile. In one embodiment, the first chamber which attaches to the barrel of the firearm comprises of sound baffling materials or gas porting baffles which vent gases from the second chamber passing rearward. The second chamber comprises of a chamber which can accommodate a retractable third chamber of the device, the second and third chamber of the device can have sound baffles to slow down the gases from the projectile.

Abstract: Disclosed is a muzzle brake for a firearm having a barrel with a muzzle and a bore extending along a longitudinal axis. The muzzle brake includes a body with an axial passageway substantially axially aligned with the bore. A high pressure chamber in the body receives combustion gases from the muzzle and includes at least one outlet port for venting a first portion of the combustion gases in the high pressure chamber. A second chamber in the body, forward of the high pressure chamber, receives at least a second portion of the combustion gases from the high pressure chamber. The second chamber has two opposing side openings in the body and includes a rear wall and a rearwardly-facing front wall upon which the second portion of the combustion gases impinge. The front wall has two rearwardly curved surfaces transverse to the axial passageway that form an apex transverse to the longitudinal axis.

Abstract: A rupturable bag assembly including a balloon, an outer wall, an inlet port, and a heat resistant shield. The balloon is fabricated from an elastic material. The outer wall is disposed around the balloon, the outer wall having a perimeter seam which parts abruptly at a predetermined tension. The inlet port passes through the outer wall into the balloon for inflating the balloon to produce the predetermined tension. The heat resistant shield is disposed within the balloon opposite the inlet port. The outer wall is constructed of a relatively inelastic material in comparison to the material used to construct the balloon.

Abstract: A solid state ignition safety device for rocket assisted projectiles having a piezoelectric generator that charges a capacitor during the initial acceleration of the projectile by the launching propellant charge. The capacitor is then discharged after a delay to ignite an initiator, which ignites the rocket motor of the projectile. A time delay circuit can be integrated into the ignition safety device to further delay the ignition of the initiator until the projectile has reached the ideal point in its trajectory to ignite the rocket motor.
