The extra overstable version of the popular Discraft Nuke, the Nuke OS is made for advanced players with the most powerful arms. This disc has the same thick 2.5cm rim that the Nuke offers, but will finish its flight with a sharp overstable fade every time. Players who throw discs this hard are going to want them to maintain their flight characteristics. The Nuke OS is available in the hard, ultra-durable Elite-Z plastic.
