M4A1-S | Basilisk
Etched with the image of a basilisk, the M4A1-S | Basilisk is a Restricted skin from The Vanguard Collection, available through the Operation Vanguard Weapon Case, with StatTrak versions obtainable. The float range extends from 0.00 to 0.68, covering Factory New through Well-Worn. At lower floats the etched basilisk detail remains sharp against the underlying finish, while higher-wear copies show the engraving becoming less defined as surface wear accumulates on the receiver and barrel. A flavor note observes that it is rude to stare, but war offers no time for such pleasantries.
Cheapest wear we have on this page. Pattern / float overpay is extra.
