M4A1-S | Blue Phosphor (Factory New).
Design
The M4A1-S | Blue Phosphor features a clean, solid coating of a vibrant, electric blue. This isn’t just any blue; it’s a luminous, almost iridescent shade that gives the weapon a sleek, futuristic, and somewhat sci-fi aesthetic. The skin completely covers the M4A1-S, leaving no part untouched by its unique color. There are no intricate patterns or complex graphics here; its appeal lies in its stunning simplicity and the pure, unblemished blue finish. The design is minimalist, letting the color itself be the star. This direct approach makes it instantly recognizable and highly desirable. It stands out in any inventory and looks impressive in-game.
Condition & Float Values
One of the most defining characteristics of the M4A1-S | Blue Phosphor is its extremely narrow float range. This skin can only exist between a minimum float of 0.00 and a maximum float of 0.08. What this means for buyers is crucial:
- Factory New (0.00 – 0.07): This is the condition where the Blue Phosphor truly shines. The vibrant blue is pristine, flawless, and reflects light beautifully. It has no noticeable wear or scratches, offering the skin in its intended, perfect state.
- Minimal Wear (0.07 – 0.08): Due to the restrictive float range, Minimal Wear versions of the Blue Phosphor are quite rare and are found only at the very top end of the float spectrum (from 0.07 to 0.08). Even in Minimal Wear, the skin retains almost all of its visual integrity. You might spot a very subtle dulling or extremely minor wear in certain spots, but it will still look incredibly clean and vibrant.
Crucially, this skin does not exist in Field-Tested, Well-Worn, or Battle-Scarred conditions. If you see a listing claiming these conditions for a Blue Phosphor, it’s incorrect. This limited availability in only the cleanest wear conditions contributes significantly to its consistent high market value and makes every available piece a premium item.
Market Value
The M4A1-S | Blue Phosphor is a high-value asset in the CS2 skin market. As of January 2026, a Factory New version commands an average market price of approximately $1133.39 on the Steam Community Market. Minimal Wear versions, while slightly less expensive, still trade at a substantial price point, often only a few hundred dollars below their Factory New counterparts, depending on the exact float value.
Several factors contribute to its robust price tag:
- Rarity: As a Classified rifle skin from The Control Collection, it’s inherently rare. This collection is no longer dropping, which means the supply is finite.
- Float Range: The extremely tight float range ensures that every M4A1-S | Blue Phosphor available on the market is in excellent condition. This consistent quality across all available items helps maintain a high baseline value.
- Visual Appeal: Its simple yet striking design makes it universally appealing. The clean, bright blue stands out without being overly flashy.
- Weapon Choice: The M4A1-S is a popular rifle, ensuring consistent demand for high-tier skins on it.
- No StatTrak or Souvenir: The absence of StatTrak or Souvenir versions simplifies the market, focusing all value on the base skin’s condition.
Prices can fluctuate based on overall market trends and specific float values, with lower float Factory New items often fetching a premium. Due to its status, the Blue Phosphor tends to hold its value well compared to many other skins.
Bottom Line
The M4A1-S | Blue Phosphor is an excellent choice for players who prioritize a clean, distinct, and premium look for their M4A1-S. If you appreciate minimalist designs and a striking color that consistently performs well visually, this skin is worth considering. Its inherent rarity and extremely good condition across all available floats mean you’re always getting a high-quality item.
While it represents a significant investment, its historical price stability suggests it’s a relatively safe bet for those looking to acquire a top-tier skin that retains its appeal. It’s less about flashy patterns and more about sophisticated simplicity and undeniable presence. For collectors aiming to complete a high-end inventory or players simply wanting one of the best M4A1-S skins available, the Blue Phosphor remains a prime contender in 2026.
