The M4 irons create a new generation of straight distance, consistency, and accuracy. A new RIBCOR design transfers more energy to the golf ball by stiffening the perimeter of the club and focusing flexibility where you make contact. Heel and toe weighting are optimized to increase moment of inertia and forgiveness by adding weight to perimeter of the clubhead. M4 irons are ideal for golfers who not only want to hit the ball longer and straighter but do it more consistently.
Straight distance and forgiveness … Forgiving and high-launching iron with a soft feel … Phenomenal Distance with these irons.
