**M4A1-S | Test Mule**

**The M4A1-S | Test Mule** is a high-performance prototype finish designed for the operator who treats their weapon like a track day car. Stripped of all non-essential paint and fitted with experimental composites, this skin embodies the raw, functional aesthetic of motorsport R&D departments.

// MANUFACTURER LORE

* **Fabricator:** HANSA TECHNIC // RENNSPORT (Racing Division)
* **Project Codename:** "ÜBERFÜHRUNG" (German for Overpass)
* **Origin:** Berlin, Germany

While **Hansa Technic** is widely known in the CS2 universe for global logistics and heavy freight (seen on shipping containers from Canals to the overpasses of Berlin), their secretive "Rennsport" division focuses on high-speed composite material testing. This weapon is their track-focused prototype.

// VISUAL ANALYSIS

* **Forged Carbon Aero:** The handguard and stock utilize a "Chopped" Forged Carbon Fiber composite - a material pioneered in modern hypercars for structural rigidity and extreme weight reduction. The anisotropic reflections simulate the chaotic weave of real carbon.
* **Titanium Exhaust System:** The suppressor features a distinct **Titanium Alloy // Temp Critical** heat gradient (Gold to Purple to Blue). This mimics the "bluing" seen on high-performance titanium exhaust headers and turbo manifolds after extreme heat cycles.
* **Chassis & Frame:** The receiver is left in a mix of brushed titanium and anodized black aluminum, similar to an unpainted race car chassis or engine block.
* **Prototype Markings:** Features the "HANSA TECHNIC" livery and "S/N: ENG-PROTO-007-N", identifying this as a pre-production engineering sample, not a retail product.

// TECHNICAL DATA

* **Finish Style:** Gunsmith / Custom Paint Job
* **Wear Range:** 0.00 - 1.00
* **Normal Map:** Features high-precision milling lines, stamped serial numbers, and carbon fiber surface texture that remains visible at all float values.

// THE "98 in 4" QC STAMP

>**R&D LOG #007 (BERLIN LAB):**  
"Hansa management is asking why a shipping company needs a titanium assault rifle. I told them the delivery times need to be faster.  
Thermal dissipation on the titanium can is optimal. Carbon furniture reduced weight by 400g. However, the ballistics test resulted in... 98 damage in 4 hits. Again. Send it back to tuning."

Made a racing inspired M4A1-S gunsmith skin. Added In-game screenshots in variety of maps. <3
