M4A1-S | Cyrex
Among the highest-rarity finishes for the silenced M4A1, the M4A1-S | Cyrex carries Covert status within The Breakout Collection and is obtainable from the Operation Breakout Weapon Case. StatTrak versions are available. The high-tech design rendered in black, white, and red reads with sharp contrast at lower floats within the 0 to 0.50 range. As wear approaches the 0.50 ceiling, the graphic design elements begin to show surface damage, but the bold three-color palette remains legible across the weapon even at Field-Tested condition examples.
Cheapest wear we have on this page. Pattern / float overpay is extra.
Operation Breakout Weapon Case: (case+key) ÷ drop chance. Average, not a promise.
Covert / missing collection peers: no contract estimate.
