Tips and Tricks
The Gunrunner mod is best used with Submachine guns and Assault Rifles. The results using this mod with Light-machine guns vary as their hip-fire accuracy is relatively bad. The L-star is an exception for the LMGs as it's hip-fire is better than most in the class.

This is for a very fast paced, in your face kind of play style and should be used very aggressively.
