The Millennium Quantum Astra-X (Xtra-Overstable) is a Limited Edition variation of the Quantum Astra. Unique conditions during production caused these discs to form with a slightly taller dome and a less steep inner wing wall, resulting in an extremely overstable flight characteristic. They are suitable for very windy conditions, dog-leg shots, or very strong throwers. Stickers placed on the tops of these discs will differentiate them from the regular Quantum Astras. These discs look sharp with crystal clear Quantum plastic featuring Stardust material. Available in weights 160-175 grams. PDGA Approved.
The Quantum Astras contain "Stardust" for a unique glimmer.
