The new Grain Flow Forged MX-300 irons with Y-Tune Pro technology are the perfect players spec iron with enhanced game improvement technologies. The head specifications of the new MX-300 irons provide a more traditional look with a minimal progressive offset, a compact head size and modest sole width to deliver the look for an aggressive player profile. The full cavity utilized in the MX-300 irons contains the reconfigured Y-Tune Pro technology for enhanced feel and ball flight control, with added forgiveness. The milled pocket cavity (3-7) redistributes 12 grams of discretionary weight low and deep to provide a high penetrating launch, while the scoring irons (8-GW) utilize a solid power bar design for maximum solid feel and pin attacking control. The MX-300 irons are the perfect weapons for the player looking for the combination of feel, forgiveness and ball control.
