As i've already explained, ghost m4 is NOTHING like normal m4. The only reason people assume this is because of the name. Ghost m4 has 0.5 less freeze which is alot, and 0.4 higher firerate, increased to 0.6 since then.

I just realised those stats posted by ventus are out dated, the recent ones fire rate is 0.242 instead of 0.26
