The firearm with pressure accumulator ( 5 ) having increased battering charge ( 3 ) and barrel ( 1 ) length has a piston ( 43 ) sliding in the accumulator housing ( 41 ) fixed to the breech ( 6 ) and springs ( 38, 38, 40 ) supporting the piston. To create a pneumatic spring ( 17 ) an annular brake chamber ( 44 ) is provided. The battering charge is arranged in the bolt body ( 31 ) located in the breech and has a neck ( 7 ) with an opening ( 9 ) facing towards the barrel to direct propellant gas to the barrel. This structure can be adapted to any size of the firearms, e.g. sharpshooter rifles with range of 4 to 6 kilometres, sky sweepers with an amplitude of 30 to 35 kilometres to combat targets by homing missiles as well as intercontinental missiles with a range of 500 to 1000 kilometres. |
