The ACR is a rare weapon in the campaign, used by Derek "Frost" Westbrook only in the mission "Scorched Earth" equipped with a Hybrid Sight. Other friendly and enemy NPCs do not carry one, and there is no way of receiving extra ammo for the weapon.
The ACR 6.8 is unlocked at Level 50 in Call of Duty: Modern Warfare 3's multiplayer. The damage output of the ACR 6.8 in Modern Warfare 3 is significantly higher than that of the ACR from Modern Warfare 2, dealing 45-30 damage, in comparison to 30-20. The ACR 6.8 retains its signature trait: the extremely low recoil, although it's slightly higher than its previous edition. With the Kick proficiency equipped, the ACR 6.8's recoil becomes near-zero, similar to its ACR in Modern Warfare 2. Combined with the fastest reload time in the AR category, these stats make the ACR 6.8 a potent weapon, particularly at mid to long range. However, the ACR 6.8 does have a slower rate of fire than some of the other assault rifles such as the M4A1 and the G36C, becoming slightly less effective in close quarters which could affect your gunfights with SMGs and other Assault Rifles. At range, however, it beats the M4A1 (requiring one less bullet), and is also superior against low fire rate guns like the CM901 and the AK-47 at all ranges.
The iron sights are somewhat bulky, but agreeable at longer range, so an optic (such as Red Dot Sight) is optional if the player wishes to use the ACR at medium-long range combat. Hybrid Sight is useful for the ACR as it potentially increases both close-medium and long range combat effectiveness, with the higher zoom optic also being useful due to the weapon's very low recoil. The idle sway, while low compared to other assault rifles, can also make it difficult to get all shots hit the target at long range, though this can be negated with Stability. If the player does not have Stability yet (as it is unlocked at weapon level 28), Kick is also ideal for longer range, as it reduces the ACR's recoil to near-zero. Attachments can be used to have another attachment, such as Silencer without having to give up an optic. Focus can help the player keep on target if shot, which can be a matter of life and death if the flinch takes the player's aim away from the enemy.
The ACR 6.8 is arguably the best assault rifle for Hardcore game modes as it does 30 damage at long range; this means that it will always be a one-shot kill anywhere to the body at any range, unless the target is behind any cover. The only other assault rifle that can match this is the MK14, which is semi-automatic, but may still kill a target hiding behind cover due to its high damage.
The ACR 6.8 is a very common sight in-game due to its good all-around stats, boasting high damage and accuracy along with a quick reload time. Because of this, one can find ammo from fallen players easily, reducing the need for Scavenger.
The ACR 6.8 is available for both Survival and Mission modes.
The ACR 6.8 is available in Survival Mode at level 14 and costs $3000. It is a starting weapon on Off Shore, with an ACOG Scope and Underbarrel Shotgun.
The ACR 6.8 is used by commando troops in later waves, which allows the player to scavenge their ammunition after killing them. The ACR 6.8 is a solid overall weapon in Survival because of its low recoil and rather high damage, which makes it effective at all ranges. As with all weapons, it is advised to go for headshots in later waves to speed up killing time and to save ammo.
