I didn't voted.
Because its obvious that m12s does easiers kills than m4.
After, if you know aim, thats the same.
m12s . . everyone legit rage about it cuz it's a hell noob weap.
I own it and it does free easy kills ^^'
You never tried M4A1 ? Own not a Silver or something ? . .
I can to leave you try if you want to, I own the 2 ones.
But you'd trying my Silver, not the normal one. :p
Anyway, if you want free easy kills + boring' ppl' + don't be Chuck Norris Approved, take the m12s.
If you want to use a bit your skill for kill', then take the M4A1 ! :'D
