The Holographic Combat Optical Gunsight (HCOG) is a weapon attachment in Titanfall. It has an open sight reticle, making it easier to track targets, especially in the vertical. The gunsight has a 1.85X fixed magnification and integrated ammunition readouts. It comes pre-attached on the Amped R-101C and the Amped R-97.
The reticule on the HCOG is the same as the ACOG in the Call of Duty series. It consists as a small red chevron, although smaller than most of the Call of Duty ACOGs. The HCOG also has better ADS peripheral vision but less zoom than the Call of Duty version.
