The Drop Compensator is a very clear sight with high zoom. It performs similarly to the CTS, but it lacks the feature that highlights enemies on radar when spotted, though it lowers the view kick of the weapon when equipped.
The Drop Compensator returns in Modern Combat 5: Blackout. It is an unlockable scope available for assault rifles, submachine guns, and light machine guns. Like its predecessor, it is a clear sight with 4X zoom.
