The ACOG Sight returns in Call of Duty: Black Ops and is available to the player for 1000. The ACOG Sight is available on the same types of weapons it has been in previous installments with the addition of a handgun, the Python. The sight differs on some weapons; for instance, the AUG utilizes its trademark Swarovski Scope.
Also, the ACOG's design differs with western European or American manufacture, there are two possible scopes; a simple cross-hair or a cross-hair with a dot. American weapons and the Kiparis use the Colt Scope, Russian weapons and the Galil use the Russian PK-AV. British weapons (L96A1 and Enfield) use the SUSAT scope. The Python uses its own special scope. Note that the reticle cannot be changed like Red Dot Sight or Reflex.
In general, the scope is smaller and more cluttered than the variants in previous games. With the exception of Sniper Rifles, ACOG's lack idle sway which was present in Call of Duty 4, but the scope's magnification still increases recoil, and the time it takes to aim down sight is also longer than in Modern Warfare 2.
