The contract
10 inputs, all Mil-Spec, all from Fracture Case. Concentrating every input in one case is what keeps your odds at 20% — mixing cases splits the probability across both pools and lowers your chance at MP5-SD | Kitbash specifically.

Input float for each exterior
CS2 normalises float across a trade-up: each input’s float becomes a 0–1 position inside its own range, those are averaged, and the average is applied to MP5-SD | Kitbash’s range of 0.00–0.80. To land a given exterior, your ten inputs must average the normalised float below.
| Target exterior | Output float | Required avg. input float |
|---|---|---|
| Factory New | 0.0350 | 0.0438 |
| Minimal Wear | 0.1100 | 0.1375 |
| Field-Tested | 0.2650 | 0.3313 |
| Well-Worn | 0.4150 | 0.5188 |
| Battle-Scarred | 0.6250 | 0.7813 |
“Not reachable” means MP5-SD | Kitbash’s own float range never enters that exterior band — no combination of inputs can produce it.
What MP5-SD | Kitbash is worth right now
