lol, with ak's high recoil, a "grunt" wont be able to use it very well. if he was a sergeant, i would recommend the UMP. moderate recoil, and high damage. For now, go with he scar-l, as jabber315 posted earlier. its very easy to control the recoil.
It depends on which map you like playing tbh. if your a deathroom/junk flea kinda guy, I prefer the mp5/ scar/ ak47su for low recoil, high damage factor in reasonably close ranges. Also, gotta have the shotgun for backup. The stairs in the upper floor of deathroom is a absolute murder zone with a shotty. The Spas-12 with and extended magazine mod rules, or if you got nx, the m-590 mariner. People will actually leave the room when you start opening up on them and 1-2 shotting them off the stairs.
ok here is a list of weapons u can use for diff zones
1.if u can aim and aim very well and get headshots adn do better with less recoil and ur patient-use m4al
2.if ur more into power and using a burst shot use the-ak47why? cuz if u just shoot with ak u hardly hit anything
3.scarl if ur both of the above use the scarl recommended if ur like me use the m4al and pwn peps very far away and at close range
gl with ur choice
IF U THINK IM HELPFUL THANK ME
