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 sweater|sleeveless]] [[ribbed sweater]] and [[skull mask]] [[black bandana|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]] [[jacket on waist|around her waist]].
