MacGregor MT-86 Irons | An icon reborn
MacGregor Golf · Custom BuiltThe original MT irons were iconic, brand-defining clubs that put MacGregor on the map. The MT-86 honors their clean lines while packing in modern technology: a thin 2 mm MS300 face with a power slot for explosive ball speed, a foam-filled head for buttery feel and sound, and internal co-forged tungsten toe weighting that lowers the CG and raises MOI so off-center strikes still fly. The OS model has an oversized head with much more forgiveness, a higher MOI and a larger sweet spot, plus slightly more offset.

Why golfers choose it
A thin 2 mm MS300 face (295 kpsi) and power slot for very high COR.
A proprietary polymer fill for soft feel and a satisfying sound.
