The HCOG is available for most primary Pilot weapons. The sight consists of a red chevron surrounded by a clear frame, giving the user a less obstructed view than the default iron sights. It has a low zoom level.
The HCOG returns in Titanfall 2, although with a massive visual upgrade. The sight housing is now much wider than before, and is only available for use on assault rifles and LMGs. Like the AOG, the HCOG now has a holographic line that slowly trickles down when bullets are fired until the weapon needs reloading.
The actual holographic reticule is the same as that of Titanfall, except red.
