Abstract
An adjustable shuttlecock including means for attaching and detaching an interchangeable tail and a head including an interchangeable weight portion and an interchangeable springing mechanism. The springing mechanism and tail may be designed in such a way as to allow for proprietary designs and logos to be added to them. Additionally, the shuttlecock is designed from durable materials, which will help provide the shuttlecock with a very long life-span. Furthermore, the shuttlecock's spring may be constructed in such a manner as to cause a noise to be made upon compression.
