what should?

Whatever you do, DON'T get the AK-47 Knife.
It possesses more recoil, reduced accuracy, slower firing rate, and the bayonet is not always a 1 hit KO.

neither .

Ak-Kinive Or M4-Costum

I don't recommended getting the Deagle gold since you could get a better gun than a side arm.

buy ak knife or w8 for m4 gold

Get m4 crystal rare and beautiful gun /yea
