Quick scoping seemed to have started in “Call of Duty 4” and got popular in “Modern Warfare 2”. A Quick scope is when a player in any game with scopes on guns holds out the scope for less than 1 second. A No-scope is when you don’t use the scope at all. and a Hard-scope is when you are in the scope for longer than 1 second.
Lots of MLG (“Major League Gaming”) Call of duty Clans use Quick scoping matches to see who is better. Faze Clan is a MLG Quick Scoping clan. Most people make montages of quick scopes that are amazing. You can find a tutorial here:
