The M4A1-S | Blue Phosphor is a Classified rarity. With a smaller magazine than its unmuffled counterpart, the silenced M4A1 provides quieter shots with less recoil and better accuracy. Multiple layers of metallic blue paint have been applied over a chrome blue base coat. Feeling blue? It is part of the The Control Collection and is available in multiple wear conditions ranging from Factory New to Minimal Wear. It cannot be unboxed from a case: it only comes from the The Control Collection itself, so the market is its only reliable source. Its float range of 0.00 to 0.08 means it only exists in Factory New and Minimal Wear, no Field-Tested, Well-Worn and Battle-Scarred copy can ever drop. The finish is dominated by blue. A Souvenir version exists alongside the standard finish and trades at its own price.
