Yea, if it was relative that guy would have a hell of a time firing it... the only explanations would be:
1- The guy is about the size of the incredible hulk. Run. Don't look back, just avoid eye contact and run from the large person.
2- IMI is catering to assault rifle owners ages 4-10. That would be kinda funny, but very scary. Laugh and run (from the 6 year olds digging up their weapons stash from the sandbox) at the same time.
