  • the invention relates to gas piston assembly used in defence industry and hunting in general, and providing ignition of cartridges at same efficiency with gas pressures having different filling such as heavy filling, light filling at semi-automatic and/or automatic fired weapons.
  • the invention particularly relates to a piston embodiment providing adjustability of mechanism setting rate and discharge of extra gas from rifle in regard to both heavy and light filling cartridges forming gas pressure at different quantities in the barrel when fired, by means of only one gas piston.
  • the invention has been developed to provide fire of the cartridges having different filling quantities, of semi automatic and / or automatic rifles by use of one single gas piston assembly.
  • the invention has been developed in order to not cause damage to user and rifle accessory when heavy filled cartridges are fired and to prevent increase in weight of rifle and volume occupied by rifle. Since the springs used in gas piston assemblies today are of conventional spiral spring standards, the rifle becomes into a position where it cannot be fired because of any breaking or deformation. Since the conventional spiral springs are the components required to be replaced completely as a result of any deformation, they cause considerable amount of cost to the user. Also conventional spiral springs used in the field expose early deformation after multi number of use.
  • the invention has been developed in order to ensure maintaining fire of the rifle even in case of any fault, breaking or deformation in the springs used in gas piston assembly.

  • Gas piston assemblies of today's state of art do not have any embodiment enabling adjustment of mechanism setting force and rate and also quantity of extra gas to be discharged from the rifle while firing the cartridges of different filling at the same rifle.
  • Dual gas piston assemblies are also used in the rifles in the invention at which heavy filling cartridges are fired in order to set the mechanism by high gas pressure and to discharge the extra gas.
  • Gas piston assemblies used for more than once cause increase in weight of rifle and thus make the use of rifle difficult.
  • EP2078916A2 entitled “takedown” relates to components providing easy transportation, cleaning by means of making it easy to dismantling and installing processes of barrel, fore-end , mechanism and other components of rifle.
  • the comparative invention numbered “DE102007019721 A1” reads as "Automatic rifle-gas pressure loader, has cartridge pushing device pushing cartridge from magazine into cartridge bearing after fixing cartridge magazine at rifle by released safety lever” .
  • the rifles containing novelty in matters similar to gas piston assemblies being subject of the invention do not contain an embodiment or assembly enabling less weight and firing in a manner where different cartridges of different gunpowder filling quantity are adjustable with less space occupation.
  • the purpose of the invention is to provide safe firing by means of only one adjustable gas piston assembly providing both setting the mechanism in a balanced pressure and discharge of gas pressure of extra quantity from the rifle caused in gas piston assembly of all cartridges from the lightest cartridges to magnum cartridges having the heaviest quantity of gunpowder in semiautomatic and / or automatic rifles by means of changing number of leaf spring.
  • Another purpose of the invention is to provide easy shot and comfortable transport of rifle by user by means of keeping at minimum level both the volume and weight of rifles used to fire cartridges of heavy filling.
  • Another purpose of the invention is to ensure continued operation of the rifle by means of providing the longest strength of the spring located on gas piston assembly against the said pressure and force and taking into operation other springs even when the spring is broken, when multi number of firing is made and the high gas pressure and high mechanism setting force occur as a result of firing heavy filling cartridges.
  • a further purpose of the invention is to provide consumption of all or adequate amount of pressure amount for re-set of the mechanism since the pressure arising as a result of fire of light filling cartridges is low.
  • Another purpose of the invention is to provide change mechanism setting force and speed by help of increasing and decreasing number of leaf spring in gas piston assembly when the heavy filling cartridges are fired at rifle.
  • the invention is a gas piston assembly usable with cartridges of different filling quantity transmitting a quantity of gas pressure spread from gun barrel to gas chamber in firing the cartridges containing gunpowder of different quantity used in semi-automatic and/or automatic fired guns, in rifles, and pressing the mechanism spring and providing firing of mechanism again for resetting and thus discharging the extra quantity of gas outside the rifle, located on the inner piston and transmitting the forces in the required quantity generated in pressing direction from piston nut located on the outer piston and outer pass.
  • the invention is a gas piston assembly which can be used with cartridges of different filling quantity containing at least one leaf spring transmitting a quantity of force occurring in pressing direction in an adjustable manner for re-setting the mechanism.
  • a preferred embodiment of the invention contains passing stage providing use of entire gas for setting the mechanism by means of ensuring continued installation of outer piston onto inner piston without space in gas pressures having low force effect arising as e result of firing light filling cartridges and by preventing removal of gas from the rifle.
  • a preferred embodiment of the invention contains a gas passing surface providing passage of gas pressure arising from fire of heavy filling cartridges through the directing ring located on ring bracket and transmission of a quantity of it to leaf spring to set the mechanism and discharge of the extra quantity from the rifle.
