About the Callaway Apex MB (2018)
The 2018 Apex MB is the muscleback that brought the Apex name to Callaway's tour blade, announced in October 2017 with US sales from 3 November alongside the 2018 X Forged cavity back, and sold largely through custom order — a 2017 launch catalogued as the 2018 model, so the year below is the announcement year per this database's convention. It is forged from 1025 carbon steel with 20V grooves, in what was Callaway's smallest blade head of recent years, with a thin sole and a crisp leading edge. Lofts are traditional — a 34 degree 7-iron and a 47 degree pitching wedge — and heads ran unusually deep, from a 2-iron through a 51 degree A-wedge, with 3-PW and 4-PW the common set makeups. Specs below are the standard men's steel-shaft numbers.

Frequently asked questions
What is the loft of a Callaway Apex MB (2018) 7-iron?
The 2018 Callaway Apex MB 7-iron has a loft of 34 degrees, a lie of 62.0 degrees and a length of 37 inches.
When were the 2018 Callaway Apex MB irons released?
Callaway announced them in October 2017 with US sales from 3 November 2017 and UK retail from 26 January 2018, launched alongside the 2018 X Forged cavity back and sold largely through Callaway's custom order program.
What is the difference between the Apex MB (2018) and the Apex MB 21?
The 2018 model is a plain one-piece 1025 forging with a 47 degree pitching wedge and a 2-iron in the range. The Apex MB 21 that replaced it added a removable tungsten swing-weight screw, a brushed finish, and a slightly weaker 46 degree pitching wedge, with the range starting at the 3-iron.
Did the 2018 Callaway Apex MB come in a 2-iron?
Yes. Heads ran from an 18 degree 2-iron through a 51 degree A-wedge, unusually deep for a modern blade, though most sets were sold 3-PW or 4-PW.
Finding a used set
The Callaway Apex MB (2018) ran from 2017 to 2020 and is no longer in production, so the used market is the only source. Search eBay, 2nd Swing, Golf Avenue and the PGA Tour Superstore trade-in listings, and check the loft and lie against the chart above before buying — sets this age have often been bent from standard.

- Note on stock shafts: MyGolfSpy's 2018 first look describes the model as sold through Callaway's custom program with Project X (PX, LZ, PXi) among the offered shafts, and period retail listings (GolfClubs4Cash, eBay) consistently show Project X 6.0/6.5 builds — Project X steel is recorded as the standard build with no flex range asserted.
- Note: bounce was not published in the sources consulted and is omitted rather than estimated. year_discontinued is 2020, the year the successor Apex MB 21 was announced (13 October 2020).
