I prefer it on my barrel as it is easier for people to see what you are shooting at and you dont end up just haveing the back of your hopper in the shot, while playing north v south I just used it on my barrel as it is also alot easier to see when it is turned on and recording and not recording , also on your head it means you gotta get lower down to not get shot in it, as when ever I see one popping up thats my target.
