m4a1_(mod3)_(girls'_frontline)
The Neural Upgraded form of Girls' Frontline's M4A1 (girls' frontline), introduced in the 1st batch in February 2018, with Singularity.
The events of Singularity would result in M4 getting a substantial change in appearance, with her only retaining her sleeveless ribbed sweater and skull mask bandana, with even the M4 she's carrying going from a tan color to black. Now armed with M16's particle cannon case, she wears detached sleeves with guarded arms, asymmetrical legwear, and a green jacket around her waist.
