M4 irons unlock a new level of straightness, distance, and forgiveness in a product designed to be the longest in our irons lineup. A breakthrough innovation in irons performance; RIBCOR is designed to help you hit it LONGER, HIGHER, and STRAIGHTER. The Fluted Hosel and 360 degree Undercut technologies produce discretionary weight that has been relocated low in the clubhead to improve launch, spin, and forgiveness.
