There are realistic M4s out there that do look like real M4s just like you see in the Army books and news and even in person, however alot of realistic M4s either do not have enough variety or little mistakes. Instead, alot of people do stuff like stick 700 yard scope on M4s or put C mags on them when they can make simple, logical M4. At most, theres only ten kinds of configurations for an M4 RIS.
I already have Inq's high res pack, but where is the Inq Do it your self M4 pack?
