What Callaway says about the Apex MB ’24 Irons:

“The new Apex MB Irons are developed for the absolute best in the game who are looking for a high level of performance in a modern Tour blade.

“With our Dynamic Sole Design, it provides more efficient turf interaction, enhanced workability, and the classic feel that elite players expect.

“The Apex MB body and face are forged as one-piece in a proprietary forging process from 1025 carbon steel, creating the purest feeling iron imaginable.

“A progressive CG throughout the set improves trajectory control. The long irons feature a lower CG that promotes towering shots that land soft into greens while the short irons utilize a higher CG for a lower trajectory with more spin for added control.

“These irons feature a dual chamfer on the leading edge to cut through the turf more efficiently. A trailing edge chamfer provides relief from the turf after contact for enhanced feel. This Dynamic Sole Design maintains speed through the turf and promotes consistent contact on all shots.”

Callaway Apex MB ’24 Irons Specs & Features

The Apex MB 24 irons have been tweaked to make these stunning new blades more workable and playable than ever before.

The muscle backs are the purest blades in the Apex range, have the least offset, thinnest topline and sole but also have a longer clubhead length than the Pro irons.

The Apex MB blades offer incredible feel from the forged 1025 carbon steel face, which is consistent across the entire set – unlike in the Pro series.

Although they have the least amount of forgiveness of the Apex irons, the MBs do have a progressive CG throughout the set to produce the best trajectory from long iron to short approach play.

These irons have a dual chamfer design on the leading edge for better turf interaction and ball striking, while the Dynamic Sole Design also works in the same way on the trailing edge.

The MB model is available in 3-iron (20.5 degrees) to A-Wedge, which is also known as 11-iron and 50 degrees.
