What the differences mean
At the 7-iron, the Apex MB (2018) is 34° and the Apex MB 21 is 34°, identical at the club most golfers compare on, although other clubs in the sets differ. Across the 9 clubs both sets share, the differences roughly cancel out, with the largest gap at the PW (47° vs 46°). The pitching wedges are 47° and 46°; the stronger one leaves a 4° jump to a 50° gap wedge, which matters when planning wedge gapping.
The sets are built differently: the Apex MB (2018) runs 2-iron to AW (10 clubs), the Apex MB 21 3-iron to AW (9 clubs).
Both are blade irons, built for low single-digit handicaps who strike the ball consistently. Compact muscleback irons with minimal offset, thin toplines and the smallest sweet spot — built for shot-shaping over forgiveness. Because they target the same golfer, the decision comes down to the specific loft, feel and shaping differences rather than who the sets are made for.
Both heads are listed as forged muscle back. The Apex MB 21 adds tungsten weighting, which lowers the centre of gravity and raises stability on mis-hits, helping the long irons launch.
The Apex MB 21 arrived 3 years after the Apex MB (2018), a typical one-generation refresh. Changes over that span are usually incremental: refined face thickness, revised weighting, updated looks and small loft tweaks rather than a new concept.
Which should you choose?
The Apex MB 21 is the stronger-lofted set — up to 1° stronger than the Apex MB (2018) on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.
