Hope this helps you decide what to use, as these class set-up's will get you 20+ kills if you know how to use the guns. I know I do.

In my opinion the 3 best guns are ACR 6.8, UMP45, and Type 95.

ACR 6.8 is unlock a little later in the game at level 50. It has 30 bullets which is the normal amount of ammo for assault rifles. The reload speed is pretty fast at about 2 secondes. It's a good gun to use and the best in the game. The silencer and/or extended mags is good for this gun.

UMP45 is unlock at the begining so you can use that. It has 32 bullets an it takes a while to reload at 2.50 secondes so you might want to put Sleight of Hand. The Extended Mags or Silencer is good for this gun. It has a good damage from close to far range.

Type 95 is unlock at level 32 which is near the begingin of the game. It has a 3 round burst weapon so if your not into that then don't use it but it will most likely kill the ennemie in just one burst. It has 30 bullets and a long reload speed at almost 3 secondes so you should use Sleight of Hand. The Red Dot Sight and Rapid fire are the best attachements for this gun.

Overall the best gun in the game is your oppinion. My oppinion is the ACR 6.8 because it has great short to long range damage and it barely has any recoil. So you shoudn't be asking people for the best gun in the game because really it's all your opinion.
