- This weapon marks a new VVIP class which is "Iris".
- This weapon is basically the modified version of the M4A1-S Transformer.
- Once again, the mounted knife is not used for melee attack - instead, players will perform a pistol grip butt on the second strike and then swing the buttock forward for the third strike.
- Unlike other weapons / game modes that use a single fixed key, this gun actually has two keys (K & Num 0) to perform weapon inspection. This was likely done to support players playing on Arrow keys so they don't have to reach out to letter key to perform the action. However, much like with MMB, it's unknown how this will affect players who already bound Num 0 to something else.
- It's actually impossible to color the gun like in the preview image, because each part (carrying handle, receiver, barrel...) only accepts one color and players can't mix a 2nd / 3rd colors in. To prevent unecessary questions, there is a description stating "Preview is only an example, actual customization may vary".
- This is the only VVIP weapon to have "double promotion" in Crossfire Vietnam. On its first inital release, this gun is sold inside a package consisting of 10 AI4 Tickets and 30-day Gloves-Flying Dragon. After the 1st promo is expired, there is another promo allowing players buying this gun ingame with 10% price dscounted.
