With our new RIBCOR technology, the M4 unlocks a new level of consistency and accuracy in a product designed to be the longest in our irons lineup. Combined with our thinnest face (1.5mm), our ultra-thin leading edge, and our thin-walled Speed Pocket, M4 iron produces golf shots that are not only long, but incredibly straight.
RIBCOR
RIBCOR localizes face flexibility in the hitting area, transferring more energy to the ball to increase distance and accuracy
RIBCOR stiffens the perimeter of the head creating a more rigid structure, enhancing sound and feel
RIBCOR mitigates toe flexibility for tighter dispersion
MORE FORGIVENESS
Optimized heel and toe weighting provides a significant increase in MOI vs. M2 '17, resulting in more forgiveness
Ultra-thin leading edge works in conjunction with the Speed Pocket to increase speed on low-face shots
MORE DISTANCE
Fluted Hosel and 360º undercut allows for redistribution of mass low in the head to increase launch distance, and consistency
Condition Guide
New
Only clubs rated 10 for our three categories will qualify for the new rating - the head, shaft, and grip will all be rated ten, brand new, and in the wrapper.
Used certified
Clubs sold as used with the “ready-to-play” certification will have a rating of less than 10 on our rating guide, but have all been thoroughly inspected by our experts. It can be anywhere between:
Like New - New, not in wrapper, un-used
Excellent - Minimal use, max. 4-5 rounds
Very Good - Used, in great condition, with no damage
Good - Used, with some cosmetic damage that do not affect club’s performance
Fair - Heavily used, with some cosmetic damage, but still playable with good performance regardless.
