Some gun suggestion

We all know the M4A1 Adv don't we?
Well one of my friends was thinking: why not make one similar to it for GP crates?
Well he was probably thinking about the default M4A1 but with a sound surpressor and maybe a bit more ammo.I saw something like it in a chinesse CF video if i remember right.
I know i'll get flamed for this idea and all.And i'm thankfull for all of you ZP buyers,i know you guys keep the game alive for us free users ,and some of you will probably say:" lawl go buy zp and get a M4 Adv nub,don't QQ here about some gp version you want"
Was my friend's idea soo..go ahead and don't flame me for this post.
