MK23-S Xmas 2019 is a festive variant of the MK23-Silencer.
This MK23 Silencer variant features a Christmas color scheme with green background and Christmas decorations on its body plus the player can hear "hoo-hoo-hoo" with jingle while reloading. It has a 13 round magazine with 39 in reserve.
- Available in all CrossFire versions.
- CF West falsely named this gun as MK23-Noel, lacking the Silencer word and thus sound like a variant of MK23 instead of MK23-S.
- Similar to CF West, in CF Korea, this gun also lacks the Silencer word on its name.
