I will mostly be using it for CQB, and it should be good for intimidation. Thanks for telling me that, I was going to get a long barrel 203. I should get a short barrel, because I am into taking out a group of guys with one well-placed shot.
Oh, and what do you mean by using youtube?
Videos on the Echo1 and ICS M203 are littered all over youtube. Just search "ICS M203" or "Echo1 M203" and you should find reviews or shooting videos, their amusing to watch cause kids usually get shot ^.^
