SO testing some thing and this happen. I keep the night vision from my mosquito all I had to do was hold down both mouse buttons and quickly swap between the nose gun and rockets.
you can also achieve permanant optics by spamming ADS, it lasts until you ADS again and you can even change weapon/class at a terminal to achieve things like thermal on max without needing to spend a million certs on implant packs to get the the thermal implant. yes this is exploiting and i say it in the hopes that the devs will fix it! (i don't use this)
