The SG 553 | Ultraviolet is a Mil-Spec-tier rifle finish in Counter-Strike 2, originally introduced as part of The Arms Deal Collection when the CS:GO Weapon Case launched in September 2013.

The float range for this finish is restricted to 0.06–0.80, so Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred are the only obtainable conditions on the open market. The restricted range is set by Valve at the time of release.

A StatTrak™ version is available, which tracks confirmed kills made while the skin is equipped and typically commands a premium over the standard finish. Active listings for SG 553 | Ultraviolet are tracked across 17 marketplaces, with prices spanning $17.06 to $213.63 depending on wear, variant, and seller.
