  • Patent number: 8453634
    Abstract: An initial velocity accelerating tube includes an outer pipe. Two ends of the outer pipe are connected with a stop member and a connection member, respectively. An inner pipe is provided in the outer pipe. Two ends of the inner pipe are inserted in the stop member and the connection member, respectively. When the initial velocity accelerating tube is mounted on a toy gun, one end of the inner pipe is against the front end of the barrel of the toy gun by the elastic force of the elastic member so as to tightly connect the barrel, providing an airtight effect. The barrel can be lengthened. To have a shoot with the long-barreled gun, the bullet can have a longer route to accelerate for getting a higher initial velocity.

  • Patent number: 8448367
    Abstract: A modular fore-end rail assembly for mounting onto a firearm includes a hand guard and a bushing element that combines with an end portion of the hand guard to encircle the standard barrel nut, thereby supporting the entire assembly without requiring modification to the standard barrel nut. The thermal transfer characteristics of the material from which the bushing element is manufactured may be selected to either increase or decrease the rate at which heat is transferred from the barrel nut to the hand guard allowing for rapid changes of bushing elements and, therefore, rapid and selective changes in the heating rate of the hand guard.

The action is of the type that includes a female threaded portion, this portion being configured to receive the threaded male portion of a rifle barrel. In this configuration, the sleeve is in direct contact with the stock, the action is in direct contact with the sleeve, and the barrel is in direct contact with the action. However, neither the barrel nor the action is in direct contact with the stock. As such, both the barrel and the action are ‘floated’ within the rifle assembly. In an alternative embodiment, the sleeve may be fabricated with the action such that the sleeve and action form a single integrated element.

  • Publication number: 20120030981
    Abstract: Several improvements to the components and assembly method of a bolt-action firearm are disclosed. An improved bolt includes two separate members, which makes the bolt less expensive to manufacture while having a stronger extension handle. An improved takedown system and buttonless stop provide two easy ways to remove a bolt from a receiver when desired without misplacing any parts. An improved scope mount has a base connected to a receiver with two ends that substantially cover the top surface of the receiver and a middle portion that is narrowed over an opening to the receiver to accommodate a cartridge. A method of assembling a firearm involves providing a barrel with a threaded portion, fitting a crush washer over the threaded portion, inserting the threaded portion into a corresponding threaded portion of a receiver, and adjusting the barrel about the crush washer until a proper headspace is achieved.

  • Patent number: 8037633
    Abstract: A handguard used on a firearm with a barrel nut having tines spaced about the outer periphery. The handguard includes a tubular body in which the inner surface adjacent the proximal end has a diameter larger than an outer diameter of the barrel nut and smaller than a diameter defined by the outer tips of the tines. Grooves are defined in the inner surface and extend longitudinally from the proximal end toward the distal end. The grooves are spaced apart around the periphery so as to correspond with the tines on the barrel nut. The body further has a circumferentially extending channel in the inner surface, spaced from the proximal end so as to receive the tines therein with the barrel nut in the tightened position to allow limited rotation of the body around the barrel relative to the barrel nut until the tines are aligned behind lands between the grooves.

  • Publication number: 20110214327
    Abstract: A two piece upper receiver for a firearm including a first piece having a front end, a rear end, a top, and a bottom, the first piece constructed to operatively carry a bolt carrier and bolt, and to have a barrel coupled to the front end. The bottom is constructed to have a lower receiver coupled thereto. The first piece includes a backbone extending along the top between the front end and the rear end, the back bone having upwardly directed indexing surfaces. A second piece overlies the backbone and includes mating surfaces engaging the indexing surfaces, aligning the second piece with the first piece. A receiving structure is opposite the mating surfaces for receiving accessory devices mounted thereon. Fasteners fixedly attach the second piece to the first piece to form a complete upper receiver.

  • Publication number: 20110185616
    Abstract: The present invention relates to a changeover system for a hand gun comprising at least two different barrels, able to be applied exchangeably on a first grip piece of a weapon, for bullets of different caliber, and/or at least two different magazines for cartridges of different caliber able to be applied exchangeably on a first grip piece of a weapon. According to the invention, the changeover system comprises at least a second grip piece of the same weapon type, provided for a smaller caliber, on which at least one security arrangement against interchange is provided, which prevents the application of a barrel and/or of a magazine of a larger caliber on the grip piece provided for a smaller caliber. If required, the user of a second large-caliber weapon can then mount components of the small-caliber weapon onto the grip piece of the large-caliber weapon, in order to fire small-caliber ammunition therewith, for example for training purposes.

  • Patent number: 7975417
    Abstract: An improved action for a bolt action rifle. The action includes a receiver containing a bolt; the bolt having two to three locking lugs surrounding a bolt face; and a threaded insert that joins the rifle barrel to the receiver. The insert also includes a series of locking lugs that mate with the locking lugs on the bolt. The position of the insert lugs relative to the barrel will position the bolt face relative to the barrel's chamber when the bolt is closed. Thus, the insert and barrel can properly set the rifle's headspace. The insert and receiver are preferably each provided with a locking lug, that serve to align the axes of the insert and receiver. The threads of the insert and the barrel are co-axial which serves to align the axes of the insert and barrel. Thus, assembled, the receiver, insert and barrel will be substantially co-axial.

  • Patent number: 7971382
    Abstract: An improved firearm having a barrel coupled to an upper receiver where the receiver includes a passageway extending generally parallel to the longitudinal axis, and a guidance feature extending along the passageway generally parallel to the longitudinal axis. The firearm also includes a lower receiver coupled to the upper receiver and a recoil spring assembly comprising a mating attachment structure and a disassembly button disposed on a lateral side of the upper receiver. The mating attachment structure is attached to an attachment structure of the lower receiver to attach the lower receiver to the upper receiver. Actuation of the disassembly button detaches the mating attachment structure from the attachment structure to detach the lower receiver from the upper receiver.

  • Patent number: 7971379
    Abstract: A firearm including a barrel having a chamber and an integrally formed upper receiver having a passageway, an accessory rail extending the complete length of the upper receiver, and a guidance feature extending along the passageway. The firearm also includes an operating rod having an anti-bounce mechanism, a bolt that is rotated counter-clockwise to lock against the chamber, a bolt carrier having a safety extension disposed below the bolt that prevents a hammer from striking a firing pin until the bolt is locked against the chamber, a lower receiver, a recoil spring assembly, and a fire control group. The bolt includes a polymer spring that biases a sliding extractor against the base of a cartridge. The sliding extractor is disposed at an angle ranging from thirty degrees to fifteen degrees on the bolt face to provide a low ejection angle from the firearm.
