well m416 cqb, and it comes with itech
i found that in snow valley (fav map), if i go to the top of the tower, i can hit campers with the m416 and itech... itech somehow really improves my acuracy
s3 silencer really helps (i like to save my gp and pick up weapons) on most guns, but on the m416's (all of them) i really hate having them silenced. I don't know y... but the sound of the gun firing somehow helps me play lol
