Utilizing a three-stage thermal treatment process, our new AZR alloy offers a more responsive microstructure for better feel, more forgiveness and more performance while maintaining the same strength as its predecessor Multi-variable wall design creates an expanded sweet spot and thinner barrel walls that are more forgiving after off-centered contact Ring-free barrel construction allows for more barrel flex and increases performance with no "dead" spots Precision-balanced barrel results in a lower M.O.I. and balanced feel for precision and control
