About M4A1-S | Nitro
The M4A1-S | Nitro in Factory New is the classified M4A1-S with the warm-tone motorsport-aesthetic illustration at FN — refined racing-themed design with bold colour relationships across the receiver.
Why FN matters on Nitro
The Nitro design depends on the warm colour relationships and the fine motorsport detail. FN preserves both at peak clarity. The M4A1-S receiver gives the design generous visible canvas.
