About M4A1-S | Nightmare
M4A1-S | Nightmare is a Classified rifle skin for the M4A1-S from The Horizon Collection. It comes in Factory New, Minimal Wear, Field-Tested, Well-Worn and Battle-Scarred (float 0.00 to 1.00), also as StatTrak™ and as a Souvenir.
On Steam it drops from Horizon Case. In the Horizon Case you get it about 1 in 94 openings, at 4.47 coins per opening with the key.
On OPCASES 5 cases have it. The best value is the Banned case, 1 in 20 for 6.00 coins per opening: 3.5× better odds for your money than the Horizon Case.
How we compare: "better odds per coin" puts the chance to get the skin (any wear, StatTrak™ or not) against the price of one opening, compared with the best official case. In other words, what it costs on average to unbox it (price ÷ chance) is that many times lower. Official odds follow Valve's published odds per rarity (Mil-Spec 79.92%, Restricted 15.98%, Classified 3.2%, Covert 0.64%, knives and gloves 0.26%), shared by the skins of that rarity in the case. Steam prices change, so the numbers are a guide and are updated daily.
