Expert Review: Titleist 620 MB & CB Irons

0

Unlike the radical change that saw the Titleist AP series retired and the T Series irons (review here) introduced, the Titleist 620 MB and CB irons only feature subtle refinements compared to the 718 MB and CB irons.

The MB stands for ‘Muscle Back’ and CB stands for ‘Cavity back’. And, although these are a continuation of a long line of players irons from Titleist, I still think it’s important to detail the changes and performance of these modern classics.

Both sets are forged from 1025 carbon steel and feature progressive blade lengths for premium feel and playability. The lofts and profiles are identical making it possible to seamlessly create a mixed set of 620 CB and MB irons.

The long irons of the 620 CB irons have tungsten co-forged into the heel and toe for greater stability, a lowered CG and a touch of forgiveness.

Much like the T100 irons, the feedback from players revolved around thinning the topline, reducing the offset and a refining the sole for better turf interaction.

When gathering images for the T Series review, I took the opportunity to sneak in a few swings with each iron and get a feel for the new 620 MB and CB irons.

With limited time, I did not have a chance to put in a proper warm up, so the numbers above are from completely cold swings. I started with the Titleist 620 MB irons paired with a Project X 6.0 shaft before testing the 620 CB irons with a Project X LZ 6.0 shaft.

Instantly, I loved the balance and feel of the MBs. As I stated in my Wilson Staff Model Blades review, muscle backs are the kind of irons I feel most confident with. The solid, forged construction translates into the fullest and most responsive feedback.

The 620 MBs are no exception, their feel is smooth and responsive. Visually the blade has a thin topline and minimal offset, but the most striking feature is the clean looks to the back of the iron. The only marking is a centered Titleist script.

I noticed many of the same characteristics as I switched over to the Titleist 620 CB irons. Just like the MBs, the CBs have a quintessential players iron look, thin topline, small offset and no visible technology or bloated sole sticking out at address.

The proximity of all the swings were very tight, the furthest offline a shot landed was only 8 yards. Taking natural swings, I saw a tight little draw, but I was also able to move a ball left to right without issue.

The Titleist 620 MB and CB irons are full performance, top of the line, forged iron sets meant for the best ball strikers in the world. Choose a complete set of one model or combine the CBs and MBs for a well-balanced set.
