M4A4 | Radiation Hazard (Factory New)

The M4A4 | Radiation Hazard is a distinctive Mil-Spec Grade weapon skin for the M4A4 in CS2, built on the classic “radiation” theme associated with high-contrast hazard styling. In-game, it’s identified by its Finish/Pattern: Radiation Hazard and uses paint index 167, with the updated CS2 model presentation.

In terms of rarity, this skin is categorized as Mil-Spec Grade, making it more accessible than higher-tier rarities. While exact drop rates aren’t publicly guaranteed for individual items, Mil-Spec skins generally fall into the more commonly encountered tier of CS2 weapon appearances. The float range (0.06 – 0.8) indicates it can appear across multiple condition states, from near-worn to heavily used visuals.

Players can obtain the Radiation Hazard skin in several wears: Factory New, Minimal Wear, Field-Tested, Well-Worn, and Battle-Scarred. StatTrak: Not available for this skin. Souvenir: Yes—this is one of the key reasons collectors seek it, since souvenir editions are tied to specific esports events and come with souvenir branding on the weapon.

Visually, the Radiation Hazard finish is defined by bold, hazard-inspired design elements intended to evoke warning signage and radioactive contamination aesthetics. Across wear levels, the look can vary noticeably—Factory New and Minimal Wear typically show stronger clarity and cleaner lines, while higher wear levels tend to reveal more texture and wear-through effects.
