The ACO (full name: Advanced Collimator Optics) is a collimator sight used by several BLUFOR, OPFOR and Independent factions in ArmA 3.

Design

The ACO features either a red-tinted bullseye or green chevron-dot reticle.

Both variants have their zeroing fixed to a range of 200 m by default and cannot be adjusted.

Dedicated SMG variants also exist for both counterparts but have reduced zeroing ranges (100 m) and are meant for use on submachine guns and other short-ranged firearms.

Like with regular ACOs, the SMG variants also cannot have their zeroing adjusted.

Variants

Arma3-optic-aco-00
Uses a red-tinted bullseye reticle.

Arma3-optic-aco-01
Uses a red star reticle.

Arma3-optic-aco-02
Functionally identical to the standard red variant but has a green chevron-dot reticle instead.

Arma3-optic-aco-03
Functionally identical to the red SMG variant but has a green T-Dot reticle instead.

Trivia

  • The ACO appears to be based on the "Railway" series of red dot sights manufactured by C-MORE Systems.
  • A unique Defunct variant exists exclusively for use in the First Contact campaign which features an ACO with its reticle disabled. Functionally however, it remains identical to regular ACO (Red) sights.
