The KING Grandsport Armlock putter is designed in a 41” setup with a special armlock-specific grip to promote the most consistent stroke for players that prefer to rest the grip and shaft against their lead forearm. A multi-material construction with SIK Face Technology creates the highest MOI possible for improved stability and roll accuracy. 3D PRINTED NYLON CARTRIDGE An intricate 3D printed nylon lattice cartridge optimizes the weight distribution within the putter head to create the highest MOI possible in a blade shape for more consistent and predictable rolls. STEEL CHASSIS A 304g steel chassis lowers the center of gravity and adds structural stability to support the other components. FORGED ALUMINUM CROWN A lightweight 21g forged aluminum crown frees up discretionary weight to position more mass around the perimeter to increase MOI. TUNGSTEN WEIGHTING 30 grams worth of tungsten weighting is combined in the heel and toe to maximize stability on off-center putts for increased consistency.
