"why would you use scope irl when you are still going to spray"
are you even aware there is no such term irl? what you refer to is called fully automatic, thats a first. you dont see the bullets unless you fire tracers, thats a second. and no, its not hard to track the target through the scope.
being such a clueless person you have a lot of balls accusing someone from a family of professional servicemen of "never firing a real gun". for the record, i've done my service as an enlisted man too
