Thinking of getting a laser for my SCAR and just wanted some opinions on whether its worth it and if so any recommendations. I'd not really seen the need for one until now, but the other week a friend who I've taken to a few games recently said a player on the other team had a green laser and when ever it was pointed in his direction it definitely had an effect on how he played, basically it made him keep his head down a lot more. Anyone that uses one find it has this advantage, can keep heads down with out even needing to use supressing fire and run through your ammo?
