MO-I stands for “Milled Oversize.” This club is designed for the mid-to-high handicap player. The large cavity back head provides outstanding forgiveness on off-center hits.The M-Series Irons are triple forged for an incredibly soft feel and CNC milled for precision accuracy. Three different M-Series Iron models are currently available: the ME-I, MA-I and MO-I. Each model is a different head size but can be ‘mixed and matched’ to create a seamless set. For example, a mid-to-high handicap player who struggles with his long irons but is consistent with his short irons may opt for the MO-I in #4-7 and MA-I in #8-PW. A KZG Dealer will determine if either a standard or blended set is best suited for each person’s game.
