Stupid question but, is it hard to notice to random people that the guns are airsoft and not real ones? they look 100% real.
Have you ever took one out in the streets or a park or something?
Walking around with a handgun, even a plastic one, would be so dangerous to do here, for so many reasons.

Strategy-wise, it really sounds like a great activity to do. I'm not a big gun fan but, the intellectual factor of this, when playing with a squad, is tempting. Closest I am to this is when playing BF3; everytime I get to play on a good squad, everything just flows from then on.
