M4A1-S | Nitro

M4A1-S | Nitro is a Restricted rifle skin from the EMS One 2014 Souvenir Package. The “Nitro” finish is applied to the M4A1-S. No key is required to open this container.

The M4A1-S costs $2,900 and trades the M4A4's fire rate for a silencer and tighter spray pattern. It surged back into the meta in 2021 after a damage buff made it competitive again. Popular finishes like the Hot Rod (full red, Covert rarity) are highly sought after.

M4A1-S | Nitro has a float range of 0.06 to 0.80 and is available in 5 wear conditions. In CS2, the float value is permanent — set at drop time and unchangeable. It controls how scratched or clean a skin looks within its wear tier. Extreme floats carry significant premiums: 0.00x copies are prized for their clean look, while 0.999x Battle-Scarred copies like the iconic AWP Asiimov "Blackiimov" are collector's items. Some skins are float-capped and cannot exist in certain wear conditions.

This skin has a Souvenir variant. Souvenir skins drop from souvenir packages earned during Major tournaments and feature gold stickers from the event. They cannot have StatTrak and are generally rarer than standard versions.

As a Restricted item, M4A1-S | Nitro has a 0.1066% chance per opening (1 in 937). Rarity in CS2 directly affects both supply and price. Higher-rarity skins drop less often, which keeps their market value elevated relative to common drops from the same case.

Prices shown are sourced from Steam Community Market and CSFloat, updated every 6 hours. Additional data from Skinport, Buff163, and YouPin. The Steam Community Market charges 15% total fees (5% Steam fee + 10% CS2 game fee), while third-party sites offer lower rates — CSFloat at 2%, Buff163 at 2.5%, and Skinport around 8% — with real-money cashout options. Beyond wear and float, the pattern index (seed 1–999) also affects price for certain finishes like Case Hardened and Fade, where specific patterns can multiply value many times over.
