Existent gas operated breech-brocks of firearms have blowback or blowback withdelaybolt and it recoil spring is supported on frame and transfers into frame allarising forces.Such firearms have hard vibration when carry out shooting in automatic mode.Invention allows carrying out more accurately automatically shooting and touse morepowerful cartridges than conventional firearms of similar destination.This achieved by supporting recoil spring on moveable part and unlocking ofbreech-block and moving this part under influence of powder gases onto piston indirection ofshot.Consequently, breech-block works in self balancing mode and bolt can goforward anddecreases loads on lock.Module of automatic, gas operated carbine that designed as proposed above hastwo gaschambers which sequentially acting in opposite directions onto gas piston.Submachine gun that designed as proposed above has main grip's surface thatformedby magazine being inserted into simplified frame.
