Full cavity inspiration
The MP-57 (Project X Rifle Steel Shaft) breaks all iron preconceptions. A full cavity Grain Flow Forged design, compacted into an inspiring overhead profile, for both forgiveness and great shot-making. Designed in conjunction with professionals on both US and European PGA Tours, the MP-57's delivers a 7% larger sweet area (than the MP-60), from a clubface just 2.5% larger. Both sole width and offset graduate through the set, offering greater forgiveness in the long irons, and more workability in the shorter irons. Custom Fit options ensure that the MP-57 can be enjoyed by both tour professionals and mid handicap amateurs.
