Double Tap is a second tier perk in Call of Duty 4: Modern Warfare, Call of Duty: World at War and Call of Duty: Modern Warfare Remastered, it is also featured as a Throwback Basic Training in Call of Duty: WWII, that decreases the delay between bullets by one third of the original delay, effectively increasing rate of fire by 33%. It has no practical effect on most semi-automatic weapons and to players who do not have a fast trigger finger (such as the SVT-40, G3, or M14). Some slower firing weapons such as the M1 Garand and the M1014 may benefit noticeably from this perk. Weapons that benefit most from the perk include Bolt Action Rifles, as the cycling of their bolts is increased, leading to a higher rate of fire from the weapon. Pump action shotguns benefit also, as the rate at which the shotgun is pumped is increased.
Due to a firecap being input on pistols and semi-automatic rifles (at 625 RPM) in Call of Duty: Modern Warfare Remastered, Double Tap is heightened in usage, as Double Tap allows the player to fire close to the original values of Call of Duty 4: Modern Warfare.
Double Tap functions best on slow firing automatic weapons with high damage. Examples of this are the M60E4 and the DP-28. It can also be used to a certain extent on weapons with already high rates of fire such as the P90 and the PPSh-41, to create weapons with incredible amounts of fire power.
A disadvantage of the perk is that it can increase the recoil on guns, which can make them uncontrollable. For this reason, it may be advisable to get as close as possible to the enemy before firing, in order to have the largest chance of hitting them. Steady Aim can be used in conjunction with Double Tap to help reduce the recoil when hip firing. Another disadvantage is that it empties a weapon's magazine faster and uses up more ammunition. Because of this, Bandolier is an advised perk to have with Double Tap, to compensate.
Despite the limited functionality on semi-automatic weapons, it can allow players with a good trigger finger to output a massive amount of damage, especially if they can hit close to the weapon's firecap, which would be close to 1200 RPM. The perk can be seen as better on PC ports of the aforementioned games, as a very popular tactic for players primarily using semi-automatic weapons is to bind the fire button the to the scroll wheel of a mouse, allowing weapons to hit thier firecap with minimal effort. However, in Call of Duty: Modern Warfare Remastered, some weapons will refuse to fire when fired too fast, to prevent spam. This effect can be seen with several weapons in the Black Ops series, where firing too fast will make the weapon not able to fire for a few seconds, or fire one shot ever second or so, drastically reducing damage output.
