Not what we called them in my outfit, it was just called a blooper. There very effective, I must say though ! You'd think by looking at them they would be a awkward bugger to shoot and kick like Hell with the large imposing bore,,but not either. They don't really have a kick per-say,,it's more like a,, push ,,about equal a 12 maybe 20 ga gauge with medium power game loads. Very Little discharge noise either, @ ear safe-ish levels. Even with that goofy stock it still shouldered half decent on the 100m range with the sight down or with it up for longer ranges, surprisingly. I remember the first time I saw one and got to fire it, I kinda gave it a strange look and said WTF is this thing?? We used them quit a bit actually , our door gunners usually kept one stashed next to them strapped to the transmission access panels on the Slicks. Awful handy for dropping rounds on bunker positions from the air while ground troops were doing ground assaults and we always had one in each squad as well.
