  • The SL8 is remodeled after its 10-rounds variant, but in-game it's depicted having 20/25-rounds magazine in-game.
  • On its buttstock there is an embossed sticker with the words "CSO".
  • The words written on the side of SL8 Custom's scope are "US. GOVT" and "KNIGHTS ARMAMENT CO".
  • The suppressor on SL8 Custom isn't functional, instead, the fire sound has more 'punch' to it.
