The Prism The Prism Pyro is debuting with a stock triple-foil stamp, that in combination with a Proton core and Prism rim produces a stunning dual-toned translucent disc. The Prism Proton Pyro was designed as Axiom’s first overstable Midrange with more glide than the MVP Deflector and a commanding stable finish. The Pyro has enough stability for consistent flights in strong winds and powerful throws without losing its line and turning off target.
