Abstract:
A bolt action rifle having a receiver; a bolt in slidable communication within said receiver, having an elongated body and a bolt head at a first end, and an exposed bolt face with a primer recess cavity having a base with a forward-facing surface, the base having an aperture therein, where the aperture is circumscribed by the forward-facing surface for receiving a propellant charge having an extended primer cap, and a firing pin within the bolt and movable between a disengaged position wherein a firing pin head is receded within the aperture and an engaged position wherein the firing pin head extends beyond the forward-facing surface into the primer recess cavity.
Abstract:
An open ignition breech plug for a muzzle-loading firearm. The open ignition breech plug includes an internal body portion for removable installation into the breech end of a barrel of the muzzle-loader, and an external body portion comprising a gripping surface, a nipple for receiving an ignition source such as a percussion cap, and at least one open portion of the external body portion for external visibility of the nipple and a percussion cap mounted thereon. The nipple can be integrally formed with the external body portion or removably mounted thereto.
Abstract:
A feeding and positioning device for toy gun comprises a barrel and a friction cylinder. The barrel has a bore, a convex hole, and a guiding groove. Two groove sides are formed at two sides of the guiding groove with circular cone shape. A width and a depth of the guiding groove are gradually decreased from the first end of the barrel inwardly. The friction cylinder has a hollow and elastic cylinder body covered at the first end of the barrel and a friction portion arranged inside the cylinder portion and inserted into the convex hole inwardly. The bullet is aligned by the groove sides and then cooperated with the friction portion to form three-point guiding position to downwardly press the bullet to be precisely fed. It may prevent the bullet from skewed error and improve the range of firing, effective potential energy, and hit rate.
Abstract:
A barrel assembly for use in a firearm that reduces the static bond due to propellant pressure between the cartridge case and the barrel chamber. The barrel assembly has a barrel with a rifled bore, and a chamber for receiving a cartridge therein. The barrel chamber having a throat portion adjacent the rifled bore, and the chamber also having a body portion for receiving the cartridge case therein. The cartridge comprising a cylindrical cartridge case, a bullet engaged within the cartridge case. The cartridge case contains a propellant producing a propellant pressure upon ignition of the propellant. A barrel sleeve configured to receive the barrel within and to positively engage the barrel. A recess is formed between the barrel and barrel sleeve, forming a propellant pressure interconnect passage. The barrel has supply ports passing from the chamber throat to the propellant pressure interconnect passage, and the release ports passing from the propellant pressure interconnect passage, and into the chamber body. Upon ignition of the propellant, the bullet is forced by propellant pressure out of the cartridge case and into the rifled bore of the barrel. The propellant pressure passes into the supply ports, into the propellant pressure interconnect passage, and into the release ports. The propellant pressure is then exerted upon the exterior of the cylindrical cartridge case. The static bond due to propellant pressure between the cartridge case and the barrel chamber is reduced and more energy is made available to cycle the firearm mechanism.
Abstract:
Methods for manufacturing firearms and firearm components from bonded multi-metallic base materials comprising at least two dissimilar metallic materials having different properties, such as weight, density, wear resistance, durability, hardness, and the like, bonded to one another are provided. The bonded multi-metallic materials may be explosively bonded multi-metallic materials. The methods involve providing a bonded multi-metallic substrate material, cutting the rough shape of a component from the bonded multi-metallic substrate material, and machining the rough component shape to a desired three dimensional configuration of the component.
Abstract:
A unitary barrel, chamber and bolt region for a firearm is manufactured from a single piece of metal stock so as to precisely and consistently meet headspace requirements. A single piece of metal stock having a bore centerline is successively reamed based on a common datum to achieve precise headspace compliance. The unitary assembly is then profiled, again based on measurements from the datum, to provide a unitary barrel, chamber and bolt region without any form of juncture, headspace or harmonic limitations.
Abstract:
An weapon system comprising: a plurality of barrels, wherein the barrels are disposed coaxially around a main shaft and wherein the barrels are held in place by at least one barrel rack; and a plurality of intermeshing, counter rotating cylinders, wherein the cylinders include a central hole for the main shaft or a lower shaft and a plurality of coaxial half-holes disposed around the central hole at the edge of the cylindrical shape to form a chamber when the cylinders mesh. An ammunition belt comprising: a first and second ammunition case, wherein each ammunition case comprises: a casing having a first and second end, wherein the first end is adapted to receive and hold a primer and the second end is adapted to receive and hold propellant and a projectile, wherein the first ammunition case is attached to the second ammunition case.
Abstract:
To permit ease and efficiency for the extraction of spent cartridge cases from the cartridge chamber of a firearm barrel within a wide range of temperature conditions, the internal tapered surface of the body region of a cartridge chamber is prepared by establishing circumferentially spaced longitudinal straight or curved regions of the internal surface finish to create an internal cartridge chamber geometry having gradually tapered spaced longitudinally relieved linear or spiral areas having longitudinal linear or spiral lands between each of the relieved areas. The circumferentially spaced lands develop controlled impedance to rearward cartridge case movement on cartridge firing to effectively protect the bolt and extractor mechanisms of the firearm against early failure.
Abstract:
A firearm for implementing an improved 9mm cartridge is provided, wherein the improved 9mm cartridge includes a 9mm bullet associated with a 45-9 cartridge casing, wherein the 9mm bullet weights at least 90 grains and wherein the 45-9 cartridge casing is configured to contain a propellant sufficient to propel the 9mm bullet to a velocity of at least 1600 feet per second. The firearm may include a barrel, wherein the barrel is configured to operably interact with the 9mm bullet and a chamber, wherein the chamber includes at least one chamber portion sized and shaped to operably associate with the 45-9 cartridge casing and a free-bore, wherein the free-bore includes at least one free-bore portion sized and shaped to operably associate with the 9mm bullet.
Abstract:
Firearms and firearm components are constructed from bonded multi-metallic base materials comprising at least two dissimilar metallic materials having different properties, such as weight, density, wear resistance, durability, hardness, and the like, bonded to one another. The components are fabricated such that the metallic material having higher impact- and wear-resistance is positioned at areas that experience impact, or that include bearing points, wear points, and interfaces with other components, while a lighter weight metallic material is positioned at component locations that don't have rigorous material property requirements. The bonded multi-metallic materials may be explosively bonded multi-metallic materials.
