M4A1-Custom Devil Wing is an assault rifle variant of M4A1-Custom featured in CrossFire.
M4A1-Custom Devil Wing features a black and purple color scheme with a glowing purple aura around its body and a devil eye on its scope. Similar to Gold Phoenix weapons, it features a special wing effect when drawing and reloading, albeit a dark wing one. On the scope, there's a devil eye whose pupil constantly opens and closes like Steyr TMP-Death Eye.
