So I was watching the movie "Heat" recently. The scene where they are robbing the armored car all of the guys with M-16s all have duct tape wrapped around the hand guards of their weapons, and I know I've seen similar things in other movies and TV shows.
What the hell is that for?
I also recall seeing pics of IDF Soldiers with these green and black bands in similar fashion on they're M16s. Is this used in the same purpose as the duct tape in "Heat"?
