In season 6, the third Officer Challenge requires getting 40 longshot kills with an ACOG scope.
Acog Longshots: Get 40 Longshot Kills while using an Acog Optic (6,000 XP)
I looked quickly through some ARs and I can't find any scopes that had the letters ACOG,
and searching it online brought me to the wiki, but I couldn't find the information I was looking for.
The wiki has a list of CoD games the scope is in, but doesn't include the new Modern Warfare:
The ACOG (Advanced Combat Optical Gunsight) is an attachment featured in Call of Duty 4: Modern Warfare, Call of Duty: Modern Warfare 2, Modern Warfare 2: Ghost, Call of Duty: Black Ops, Find Makarov: Operation Kingfish, Call of Duty: Modern Warfare 3, Call of Duty: Black Ops: Declassified, Call of Duty: Black Ops II, Call of Duty Online, Call of Duty: Ghosts, Call of Duty: Advanced Warfare and Call of Duty: Modern Warfare Remastered.
Does anyone know which guns have an ACOG scope, or scopes that count toward this progression?
I like completing all these Officer Ribbon Challenges.
