M4A1-S | Blue Phosphor

Built around multiple layers of metallic blue paint applied over a chrome blue base coat, the M4A1-S | Blue Phosphor is a Classified rifle skin from The Control Collection with no associated case. StatTrak and Souvenir variants are unavailable. The float ceiling of 0.08 restricts all copies to Factory New or barely used Minimal Wear condition, ensuring the layered metallic blue finish retains its deep, reflective quality on virtually every specimen. The interaction between the chrome base and the overlying metallic layers creates a shifting blue luminosity that is most pronounced on lower-float examples.
