Main weapons I use, M4A1 with scope, AUG A1, G36E, MP5 with scope (Junk Flea), all with S3 Supressor. The M4A1 is probably the best all around weapon to use on all maps, the AUG A1 for mid range shots and some longer shots if fired in bursts same with the G36E, the MP5 on small maps because of it's fire rate and accuracy. The other guns just jump around to much due to the recoil of them and aren't accurate or powerful enough to be effective.
