Doing a strong hand mag change is not really a huge deal. Each and everyone of those guys lowers their heads and looks down at what their doing, that to me is more of an issue. If you cant fluidly do a mag change while looking down range your doctrine needs to change. Also remember commies don't exactly design rifles they way our current trends are. Things like "Modularity" "customizable" "ergonomics" and "fluid manual of arms" aren't top priority. Something that can be mass produced as cheap as possible with available home grown materials and goes bang every time conscript 008457 pulls the trigger is the fundamentals of red rifle building.
