- "The rugged ACOG is the preferred gunsight of US forces and police sniper units."
— In-game description
The ACOG Scope is a weapon attachment featured in Tom Clancy's Rainbow Six: Vegas 2. Since Vegas 1 and 2 share the same engine and models, it appears in the same configuration as its Vegas 1 counterpart. The ACOG replaces a weapon's default iron sights and adds a 4x scope that the player is able to view through. The ACOG Scope can be equipped to assault rifles and submachine guns in-game. The attachment cannot be equipped to light machine guns, sniper rifles, and shotguns.
Note: If a player is looking through an ACOG Scope behind cover in third person view, the player's whole view is zoomed in with the sight's corner zooming into the ends of the screen.
- As with Vegas 1, the default ACOG sight model is based on the Trijicon ACOG scope.
