MT4

The MT4 is a fictional firearm based somewhat off of the CMMG Mutant rifle. The CMMG is an AR15 platform rifle chambered in 7.62x39mm.

Overview
The MT4 is a high damage burst fire assault rifle. It's actually capable of killing a target in one burst. The MT4 works at all ranges, but is best at close and medium, as it has a very rapid TTK. It used to fire in fully automatic, and was nerfed to compensate for the high stopping power and rapid fire.
