The new MP-52 irons with Dual Muscle™ Technology are the most playable MP irons ever! The performance of the MP-52 iron set is based upon two innovative technologies. Comprising Dual Muscle™ Technology is an outer muscle pad which allows for a precisely placed, lower and deeper center of gravity, offering enhanced playability and an ideal launch angle, and an inner muscle pad which provides unparalleled feel and the feedback that better players demand. The second innovation that stets the MP-52 irons apart and advances MP iron playability to a whole new level is a patented CNC milled pocket cavity. Two deep crescents milled into the club head allow for the redeployment of 14 grams of mass for a lower and much deeper COG. The performance advantages of this feature are increased playability on miss-hits and superior launch. These advanced features are combined with a classic head profile to deliver tour level looks, feel, and playability.
