I was discussing the slot 4 weapon with my BFF, trying to figure out what kind of gun we thought we were looking at here, and we were kinda stumped. These "machine guns" look like chimeras of different parts. We've got hefty muzzle breaks, wood front grips, brick magazines, pistol grips...
The only thing I'm willing to wager here is that they're probably not chambered in a heavy or full power cartridge, as that would tread on the minigun. I THINK they're full-size submachine guns, but I'm not entirely sure. They could maybe be some brand of ultra-lite LMG chambered in 5.56 NATO.
What was the design process for these things? Are they completely original, sourced from somewhere else, inspired by anything?
