Heckler & Koch MP5 S-E-F (Sicher – safe, Einzelfeuer – single fire, Feuerstoss – fire) select fire trigger pack.
A select-fire weapon is defined as a weapon being capable of multiple modes of fire: specifically, it must have a semi-automatic mode and at least one fully automatic mode, either burst (auto with a limiter of some kind) or unrestricted auto. Some weapons have both.
A weapon which only has safe and auto settings is not select fire.
