Using the Quick Scoping technique

Have you ever been playing Modern Warfare 2 and watched a replay of yourself getting killed by a player using a sniper rifle who seemingly "guessed" where you were? These kills will generally be near to mid-range kills (not traditional sniper kills). Have you ever wondered how in the world the other player did that? Most people assume this is a hack, but in fact it is not. It is a tactic that many experienced players employ called "quick scoping."

What is Quick Scoping?
Quick scoping refers to the tactic of quickly aiming down the sight or scope of a weapon and firing almost instantly. Generally, sniper rifles are the weapon of choice for quick scopers’, but in reality any gun equipped with an ACOG or telescopic sight may be used. Sniper rifles are preferred because of their powerful nature. This tactic is usually employed only by experienced gamers as it is a very difficult (but by no means impossible) skill to master.

How does it work?
The basic concept is as follows: the player quickly presses the aim/zoom button so that he is aiming halfway down the scope. As soon as the scope appears white, the accuracy of the gun is improved dramatically (when compared to hip firing). This effect is particularly strong with sniper and bolt-action rifles - the hip fire accuracy becomes the cross hair accuracy (when zoomed in), which allows the player to achieve highly accurate shooting with minimal time spent aiming/zooming.

How do I set up my build-out to quick scope?
Beyond selecting a gun that is equipped with a scope, there are a number of steps that need to be taken in order to maximise your quick scoping effectiveness. The first component we will look at is sensitivity.

When considering the sensitivity you want your controller set to when quick scoping, there is a little leeway. You want to make sure that you have very quick reactions, but you also want to be sure you are still able to reasonably control your character. I would recommend setting your sensitivity to no lower than a 7, but you may go all the way up to 10 if you are comfortable.

The button layout you choose to use for quick scoping is also a very important component to your success. Tactical is generally the preferred choice among top gamers as it allows the player to get down and pop back up very quickly, which minimises exposure to enemy fire. You can be successful with any button layout, but getting comfortable with the tactical layout will in the end make quick scoping much easier. It will take some time to get used to if you are currently playing with the default layout, but in the end the change to tactical will be worth it.

Conclusion
In the end, quick scoping is not an instant recipe for success, it is a very difficult strategy to master. The only way you will become proficient is through hours of practice. Take the advice here and combine it with videos available on the internet demonstrating quick scoping and you will eventually get the hang of it.
