Adding crosshairs to hip fire aim? (Ps4) [ Edited ]

[CDMtrix]

I have seen on multiple people using a blue smaller crosshair that is continuously showing while there in hibernation fire mode. I'm on ps4 and was just curious on how I can add this onto whenever I play?

Update I attached a picture if what it looks like.
