The M4A4 | Bullet Rain is a Covert-tier rifle finish in Counter-Strike 2, originally introduced as part of The eSports 2014 Summer Collection when the eSports 2014 Summer Case launched in July 2014.

The float range for this finish is restricted to 0.02–0.46, 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 M4A4 | Bullet Rain are tracked across 17 marketplaces, with prices spanning $76.06 to $3,500 depending on wear, variant, and seller.
