Spotted: New Callaway Apex MB Irons
GolfWRX spotted a new set of Callaway Apex MB irons at the CareerBuilder Challenge on Tuesday, where they were being tested by Callaway Staffer Patrick Reed.
Callaway currently sells a set of Apex MB (muscleback) irons, released in late 2014, but the new irons are noticeably different. They have a chrome finish and a streamlined muscle pad, which gives them a more traditional look than the original Apex MB irons.
Old vs. New

According to our boots on the ground, Reed tested the new irons only briefly, hitting the 6 iron and pitching wedge on the range. It’s not clear if he plans further testing of the irons.

At Address
In last week’s BMW South Africa Open Championship on the European Tour, Rory McIlroy used a set of Callaway Apex MB irons that looked similar to the new irons.

It’s unclear if Rory’s irons are an initial prototype of the new model, or customized to his specific needs.
See MORE PHOTOS and what GolfWRX Members are saying about the new irons in our forum.
This week, we have our Tour Photographer, Greg Moore, on the ground at the OccuNet Classic at Tascosa Golf Club in Amarillo, Texas, for the 14th event of the 2026 Korn Ferry Tour season. With that, we see some great things in the Lead Tape Report as we roll into Amarillo.
Joel Thelen
Monday Qualifier, Joel Thelen is in the field this week. He has played on the Korn Ferry Tour for a full season in 2023, and he is back in action this week. A couple of clubs caught my eye this week in his bag.
First off: His trusted Titleist 816 H2 hybrid. This club came out in October of 2015, and it still remains strong in the bag. Also, take a look at this Odyssey White Hot OG 7, putting a capital S in the 7S model. This custom neck has some impressive lean for an arm-lock-style putter. The bottom of the putter is covered in tape for optimal weighting.
Mitchell Meissner
Taking a look at Mitchell Meissner’s bag this week, we have some great lead tape coverage. Top to bottom working from fairway metals, irons, and wedges. We can see on the short irons and wedges that there is tape at the base of the grip, adding a little counterbalance. Along with that, some tape on the short irons and wedges as well. Moving to his putter, he rolls the Odyssey 7 Bird putter. Meissner putts left-handed and strikes the ball right-handed.
Bud Cauley had >14 clubs in his bag when photographed prior to the Memorial Tournament.

- macedan: “Started with a hand-me-down Golden Bear set from my brother when I was in high school, never really played more than once a year or got into the game until about summer of 2017. First purchased a set of Cleveland CG4’s (I actually really miss this set sometimes, soft & not terribly large for a GI iron), moved into Nike Vapor Fly’s by the end of the year. Those lasted until spring of 18 when I decided I wanted new, so I traded them in for TM Rbladez. Honestly, although I liked the Rbladez, poor decision on my part, I think this was really about the only time so far that after a week or two I was kicking myself for not staying with what I had. Rbladez stayed with me until late last summer when I switched to P790’s and (knock on wood) I am hoping this will be my longest lasting set.”

It is exactly same look of MP 69 except 4D concept.

HEY!!! That’s a design ripoff of that one company who ripped off that other company who took their design from that one company who copied that other person who’s club looked really similar to that other one!! Unbelievable Callaway…

They are the same design as the titelist 660’s take look…

Agreed. Does the groove spacing have any impact on spin rate?

The Mizuno MP-14/29 muscle design never gets old…

As if they’re the first ones to have that design.
Henny Bogan
Feb 16, 2017 at 12:24 pm
I believe the Hogan Precision (1953 or 1955) were the first to have the “Mizuno MP 14 or 29” muscle design.

Simple and clean is always sexy. If they have good turf interaction and a soft buttery feel, I would game them!

The satin finish looks much better.

No, it does not.
Bob Pegram
Jan 21, 2017 at 2:34 pm
It does when you put your club down behind the ball and the angle causes you to get a face full of reflected sunlight. The satin finish doesn’t do that.
Satin is Better

Yes, it does.

What Rory played in SA was likely a proto set of MBs he got as a farewell present from Titleist before jumping to Nike. They probably said he can stamp it with whatever he likes even their compeitors name. Three years later here we are. Why else are Callys new Epic woods so similar in looks to Titleist’s 915 line – probably also protos from them.

I would try them compared to titleist mb which they now look exactly alike. That was one of the nice things about the “old” apex mb. The look. These do. Itching for me but I’ll wait, see, compare numbers
Max
Jan 19, 2017 at 12:17 pm
They are blades buddy, your strike will be the only thing changing the numbers by a noticeable amount.
Mr. Callaway..
