Rapid Fire

Rapid Fire is an attachment exclusive to submachine guns in Call of Duty: Modern Warfare 2 that increases the rate of fire of the gun it is attached to. It is the replacement for Double Tap and has the exact same effect; the delay between shots is decreased by one-fourth, effectively increasing the weapon's rate of fire by one-third. Obtaining 30 kills with the Rapid Fire attachment will unlock the Akimbo attachment. Logically, this attachment adds recoil to the gun when fired in full auto mode. It should be noted that the game weapon stats are wrong. The rate of fire never caps, so there should be no worries in attaching this to a weapon such as the Vector. Rapid Fire works well with Akimbo, leading to some ridiculously fast close to mid-range kills. If combined with Stopping Power, at close to medium ranges it will kill instantly.

Tactics

 * It is recommended to attach Rapid Fire and Akimbo if using Bling and Steady Aim, because at short range, it applies a fury of bullets comparable with Akimbo G18s.
 * It is not recommended to attach Rapid Fire to an SMG if the class had Sleight of Hand on it since it will drain one's ammunition quickly.
 * It is recommended that the player fires in bursts if attaching Rapid Fire to submachine guns. (Except for the Vector due to its low recoil)
 * If a player is trying to get the Mach 5 challenge, it is strongly inadvisable to use Rapid Fire due to the higher chance of bullets being fired even after the target is dead.
