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.

Both StatTrak™ and Souvenir variants exist — the StatTrak™ counter tracks confirmed kills, while Souvenir copies drop only from cases collected during Major Championship matches. Active listings for SG 553 | Ultraviolet are tracked across 21 marketplaces, with prices spanning $10.72 to $219.40 depending on wear, variant, and seller.
