M4A1-S | Blood Tiger is a Mil-Spec rifle skin from The Arms Deal 2 Collection, which entered the CS2 economy alongside the CS:GO Weapon Case 2 in September 2013.

The float range for this finish is restricted to 0.00–0.30, so Factory New, Minimal Wear, and Field-Tested are the only obtainable conditions on the open market. Battle-Scarred examples are not produced, so the most worn copies still retain a relatively clean appearance.

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 M4A1-S | Blood Tiger are tracked across 17 marketplaces, with prices spanning $4.90 to $45.42 depending on wear, variant, and seller.
