Modern Warfare 2 pro's overpowered weapon tuning makes LMGs 'faster' than meta SMGs

LMGs usually have slow sprint-to-fire speed due to their heavyweight; however, this tuning method improves their stats in almost every way regarding mobility.

The Rear Grip and Laser attachment categories of the guns make the most significant difference in sprint-to-fire speed.
