Holorifle focus optics
Weapon mod case.
This mod increases the weapon's damage by 25, from 80 to 105.
The mod box is labeled "Gun Runners", yet it is stated that Elijah created the holorifle himself, not the Gun Runners, which assumes they couldn't have made the mods for it. However, this is because the holorifle focus optics doesn't have its own GECK image so gets the generic Gun Runners mod box image in its place.
