Publication number: 20140352192Abstract: This invention is a precision weapon that utilises solely as a projectile, a precision-ball made out of a suitable material namely solid C260 brass. It employs a smoothbore precision-barrel with a metal toothed rack/rail affixed along the northern hemisphere of the muzzle of the barrel that effectively converts some of the forward motion of the ball into rotational motion so that the ball is mechanically forced to rotate upwards/backwards at very high speed that can run into millions of rotations per minute, vastly improving it's ballistic coefficient and downrange accuracy. The weapon can be produced in a variety of existing types of firearms such as bolt-action, falling-block or semi-automatic, and can be chambered for a variety of calibers. A 5.5625 mm caliber bolt-action rimfire weapon for instance will provide a user with a weapon ideal for hunting small-game or for target shooting purposes.Type: ApplicationFiled: December 12, 2013Publication date: December 4, 2014Inventor: Steven Mark Camilleri

Patent number: 6662797Abstract: The invention provides a barrel for a gun having a portion comprising a substantially transparent material. The barrel can be made of any substantially transparent material including a polycarbonate or glass, such as tempered glass. The barrel is coated with a substantially transparent material to add hardness, which provides scratch resistance, and prevent deterioration of the substantially transparent material. A barrel assembly is constructed by attaching the barrel to a gun housing, also called a barrel cage, comprised of a stiff material, for example metal such as aluminum. In another aspect of the invention, an expansion chamber is provided having a housing with a portion comprising a substantially transparent material, such as a polycarbonate or glass, such as, tempered glass. The housing is coated with a substantially transparent material to reduce scratching and absorption of pressurized gas into the transparent material.Type: GrantFiled: November 27, 2000Date of Patent: December 16, 2003Assignee: Pursuit Marketing, Inc.Inventors: Samuel Jared Freeman, Brian Sullivan

Patent number: 6494195Abstract: A barrel assembly for a pneumatic paintball gun includes a barrel body and a barrel insert. The barrel body has a breech end, a muzzle end, and a barrel bore extending longitudinally through the barrel body from the breech end to the muzzle end. The barrel insert has a breech end, a distal end, and an insert bore, and is configured to be removably housed within a breech portion of the bore of the barrel body. The breech end of the barrel body is configured to attach to a breech end of the paintball gun. The barrel insert collaborates with the barrel body to provide a firing bore for the barrel assembly which guides a paintball fired from the breech end of the gun through the barrel and out the muzzle end of the barrel body. The barrel insert can be constructed having a thin, flexible wall so as to permit lateral deformation of the barrel insert.Type: GrantFiled: December 22, 2000Date of Patent: December 17, 2002Assignee: Smart Parts, Inc.Inventors: Roderick A. Perry, William Gardner, Jr.

Publication number: 20020104523Abstract: A lacquer bullet gun barrel, having a barrel case, concentrically surrounding a boring and having a rear end that is fastened to a front end of a gun case. The rear end of the barrel case has a cavity, receiving an insertion tube, which has a diameter equal to said boring and is aligned with said boring on a common axis. With this assembly, lacquer bullets tightly fit into the insertion tube, so that gas drives lacquer bullets therein with high pressure. Aligning the insertion tube with the boring ensures firing precision and an increased firing range.Type: ApplicationFiled: February 5, 2001Publication date: August 8, 2002Inventor: Chih-Chen Juan
