Everyone's favorite custom minifig blasphemer, Morgan190, returns with these two gunners.
The first is a World War style rifleman who stays pretty true to form, while the second figure uses a combination of LEGO, custom, and action figure parts to create an autogunner from a dystopian future.
I know purists like to give Morgan a difficult time for not using parts from "The Big L", but I really don't see what the issue is. Don't think of them as action figure parts, just think of them as accessories that haven't realized they were made for minifigures yet...
