The MCX 300 is a SIG Sauer's rifles that has controls similar to the AR-15 and was a direct result of the success seen with the MPX SMG. The increasingly popular 300 Blackout round is similar to the 5.56x45 mm round but increases stopping power and penetration. The stats found with the MCX is high stopping power and accuracy but like many rifles in the game it is outclassed by the M4 as maneuverability is not a very important stat.
