Two problems here:
1-> You're not using a M4 Carbine with double tap..
2 -> If you are not using a M4, you better be using a Skorpion..
Personally, if I use the AK47, I have no attachments on it. The silencer does not much good, grenade launcher's are not my suit of fun, Red dot on a AK is just silly, and ACOG doesn't fit me. I'm personally not a fan of the AK. Usually I play in hardcore server's, so my need's of silence go away.
