Frequently Asked Questions

Factory New (FN) UMP-45 | Bone Pile skins have float values between 0.00-0.07, showing minimal to no visible wear. Minimal Wear (MW) floats range from 0.07-0.15, with slight scratches or fading. This skin has a restricted float range (0.06-0.34), meaning Battle-Scarred versions don't exist. The price gap between FN and MW varies by finish — some designs like the Bone Pile pattern hide wear better than others, making MW versions a strong value alternative.

Yes, the UMP-45 | Bone Pile is an excellent budget-friendly choice. Priced affordably, it offers the Bone Pile aesthetic without breaking the bank. Budget skins like this are ideal for players building their first inventory or those who prefer spending on multiple skins rather than one expensive item. The lower price point also means less financial risk if you decide to trade or sell later.

Field-Tested covers float values from 0.15 to 0.37 on the CS2 wear scale. This skin's own floats run 0.06-0.34, so its Field-Tested copies sit between 0.15 and 0.34. Within that band a lower float looks cleaner in game and usually sells for more, so two Field-Tested copies of the same skin can be priced well apart. Every listing's float is shown in the marketplace table above.

Right now the Field-Tested is quoted at about $5.10 and the Minimal Wear at about $5.09, so the Field-Tested costs 0% more. How much of that gap is worth paying depends on the finish: wear shows first on edges and raised areas, so on some designs the cleaner wear is hard to tell apart in game. Switch wears above to compare the two side by side.

The UMP-45 deals 35 base damage per bullet. Per shot at point blank that is 140 to the head, 35 to the chest or arms, 43 to the stomach and 26 to the legs, before armor. Damage falls off to ×0.75 every 500 units.

Only without a helmet. A headshot does 140 to a bare head but 91 through a helmet, so a helmeted player needs 2 shots.
