Holo

Summary
The Holo was an optical attachment for the MP5 and the M4A1 that was used mainly for testing purposes.

It added a small scope to the gun which didn't actually zoom into its surroundings and you would use as you would normally ADS.

Background Summary
In his warehouse, PlaceRebuilder built this optical sight out of scratch. Even though it did nothing, clearly this was favored among many during the DEMO because nearly everyone had it.

Within a surprising amount of time, Place managed to detach it from everyone's guns, and toss it into a fire.
