  • Publication number: 20130219765
    Abstract: A firearm with a barrel fixed to a firearm body by at least one screw, wherein the firearm body includes a housing to receive the barrel and wherein the screw is fixed to the firearm body so that the firearm body tightens against or grips the outer surface of the barrel. In order to strengthen the connection between the barrel and the firearm body and fully ensure that the former does not move in either a longitudinal or rotary direction in relation to the latter, the barrel includes at least one surface hollow on its outer surface, and part of the screws already fixed to the firearm body are arranged inside a surface hollow, so that the screws inserted partly into the surface hollow provide longitudinal and rotary locking of the barrel against the firearm body.

  • Publication number: 20130219764
    Abstract: A bolt assembly for a firearm, wherein the bolt assembly is intended to move inside an inner cavity of a receiver of the firearm and comprises a body, a removable bolt head, at least one protruding element that tends to protrude elastically from the body, so that when allowed to protrude elastically unhindered, the bolt assembly cannot be inserted inside the inner cavity of the receiver. The connection of the bolt head to the body causes the protruding element to elastically contract, enough to allow the bolt assembly to be inserted inside the inner cavity of the receiver. Thus, a single elastic protruding element enables the user to be warned if trying to assemble the body without the bolt head into the receiver.

  • Patent number: 5109622
    Abstract: A rifle which is comprised of a barrel, an internal striker, a firing device connected to the striker, and a base which includes the butt and the lower part of the weapon. The striker receives a spring in a hole, which rests in a rear plug of the barrel. The firing mechanism is connected to a bolt lever and safety which inserts transversely therein. The firing mechanism is at the same time a safety, since when the weapon is loaded it is in non-firing position, and the outside activation of the safety catch is necessary to make the discharge.

A continuation of this opening, which is circular, receives replacement nipples controlled by the end of the opening itself and by a pin that goes through the base body. A nut plugs the opening in the tubular body and is screwed onto the other inside end of the base body. The nut is provided with a rod which passes through the pin and the nipples. A further accessory is provided in the form of a ramrod provided with metal ends pressure-fit and secured to the wood body of the ramrod by some notches that penetrate into the wood of the ramrod.
