The ERCO (full name: Enhanced Rifle Combat Optics) is a low powered riflescope exclusively used by CTRG operators in ArmA 3 Apex.
The ERCO has a magnification strength of 2x, and has a backup red dot sight located above the primary optic for use in close quarter encounters. It is available in either a chrome black, green khaki, or desert sand finish.
Although it can be mounted on any weapon with a compatible top rail, it is primarily seen attached to both the SPAR-16 or SPAR-17 series of assault and designated marksman rifles.
Trivia
- The ERCO is based on the real-life "BRAVO4" battle sight while the top mount reflex sight is based on the "ROMEO3"; both of which are manufactured by SIG Sauer.
