FIELD: weapons and ammunition.SUBSTANCE: invention relates to weapons, namely to machine guns. Machine gun comprises breech frame 1 with window 2, rotary shield 3 with spring 4, moving parts 5 with gate 6 and extractor 7, reflector 8, pusher 9, additional reflector 10. During firing moving parts 5, by moving along breech frame 1, retain sleeve 11 in gate 6 by extractor 7. In direction of recoil movable part 5 by acting via pusher 9 on shield 3, rotate said shield thereby opening window 2 of breech frame 1. At impact on reflector 8 sleeve 11 through window 2 is reflected from breech frame 1. Additional reflector 10 changes path of sleeve 11 by directing it into a safe zone for shooter.
