M4A 1 is an AR assault rifle, which belongs to the functional gun type and reduces the evasion of a single target by 96%. This skill is not very useful, and if it is in the BOSS war, there is a great chance to throw it on the soldiers. So M4A 1 is not very practical at present. It might be good if it is strengthened later.
Of course, if you like M4A 1, you can still cultivate it. To a great extent, girls' frontline belongs to the game of collection and cultivation, and it is also possible to cultivate M4A 1.
