About the Titleist 620 MB
The 620 MB is Titleist's muscle back, a single-piece 1025 carbon forging with the least offset in the range — 2.3 mm at the 3-iron falling to under a millimetre at the pitching wedge. Lofts are the weakest Titleist sells, and identical to the 620 CB sold alongside it: a 35-degree 7-iron and a 47-degree pitching wedge, six degrees weaker at the 7-iron than the T200 of the same period. It is sold 4-PW as standard, with a 3-iron available.

Where it sits in the lineup
Introduced in 2019, the Titleist 620 MB is a current blade set in the Titleist range as of September 2026, with no replacement announced. It replaced the Titleist 718 MB. New sets are built to the standard lofts, lies and lengths in the chart above, though a fitting can move any of them — so confirm the numbers on the order sheet. Used sets appear on eBay, and should be measured against this chart before buying.
- Titleist official 620 MB product page, archived 18 October 2021: titleist.com, archived 2021 — manufacturer specification table. The 9-iron (36.00 in) and pitching wedge (35.75 in) lengths are taken from this table; the 2nd Swing table below lists them a quarter inch shorter, which is a retailer error.
- 2nd Swing Golf specification table for the Titleist 620 MB iron set (2ndswing.com) — supplied every loft, lie, length and swing weight above, the offsets for the 3 through 9-irons, the Project X stock shaft and the 4-PW stock set.
- Note on offset: the source publishes offset in millimetres (2.3 mm down to 1.1 mm at the 9-iron), converted to inches here. Its pitching wedge row reads '0.09mm', which is two orders of magnitude out of step with the rest of the column and is plainly a typo, so the PW offset key is omitted rather than guessed.
- swingyard.com 'Titleist Irons By Year' — the 620 MB and 620 CB were released in 2019.
- Note: bounce is omitted — the source table did not carry a bounce column. Confidence is medium. year_discontinued is null; the 620 MB remained in Titleist's range in the sources retrieved.
- Status check, 29 September 2026: confirmed as a current model with no replacement announced. Listed on Titleist's irons page (titleist.com).
