How to Trade Up to MAC-10 | Sakkaku
MAC-10 | Sakkaku drops from Revolution Case, so any contract that can produce it needs 10 Mil-Spec skins from that same case. Here is what the contract costs, what else it can land on, and the input float you need for each exterior.

Buying is cheaper than rolling. A Battle-Scarred MAC-10 | Sakkaku costs $0.35 outright, against $0.60 for a contract with a 20% chance of producing one. Trade up for the process, not the value.
The contract
10 inputs, all Mil-Spec, all from Revolution 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 MAC-10 | Sakkaku specifically.

What else this contract can land on
A contract from Revolution Case draws uniformly from every Restricted SMG skin in the pool, so MAC-10 | Sakkaku is one of 5 equally likely results. These are the other 4.
| Outcome | Odds | Cheapest price |
|---|---|---|
| M4A1-S | Emphorosaur-S | 20% | $0.43 |
| Glock-18 | Umbral Rabbit | 20% | $0.38 |

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 MAC-10 | Sakkaku’s range of 0.21–0.79. To land a given exterior, your ten inputs must average the normalised float below.
| Target exterior | Output float | Required avg. input float |
|---|---|---|
| Factory New | — | not reachable |
| Minimal Wear | — | not reachable |
| Field-Tested | 0.2950 | 0.1466 |
| Well-Worn | 0.4150 | 0.3534 |
| Battle-Scarred | 0.6200 | 0.7069 |
“Not reachable” means MAC-10 | Sakkaku’s own float range never enters that exterior band — no combination of inputs can produce it.
What MAC-10 | Sakkaku is worth right now
Worth comparing against the contract cost above before you commit: buying the skin outright is frequently cheaper than rolling for it.
| Exterior | Price | vs. contract cost |
|---|---|---|
| Battle-Scarred | $0.35 | −$0.25 |
| Well-Worn | $0.38 | −$0.22 |
| Field-Tested | $0.80 | +$0.20 |
