What the differences mean
At the 7-iron, the 623-M is 33° and the 902-OS is 31°, a 2° gap. Each degree of loft is worth roughly 3 to 4 yards of carry at the same swing speed, so the 902-OS should carry roughly 6 to 8 yards further with that club, on a slightly lower, shallower flight than the 623-M. Across the 7 clubs both sets share, the 902-OS averages 2° stronger, with the largest gap at the 4-iron (23° vs 21°). The pitching wedges are 45° and 43°; the stronger one leaves a 7° jump to a 50° gap wedge, which matters when planning wedge gapping. Beyond loft, the 902-OS 7-iron sits 0.5° flatter (62° vs 61.5°), which nudges start direction slightly right for a right-hander.
The sets are built differently: the 623-M runs 4-iron to PW (7 clubs), the 902-OS 4-iron to AW (8 clubs).
The 623-M is a players iron and the 902-OS a players distance iron, so they sit one step apart on the forgiveness scale. The 902-OS is the more forgiving design, with a wider sole, more offset and more perimeter weighting for roughly 5 to 15 handicaps who want extra distance from a compact head. The 623-M trades some of that for a more compact head, thinner topline and more control over flight and shape, which suits roughly scratch to 10 handicaps.
The 623-M is listed as forged muscle back with a milled tuning slot and the 902-OS as forged. The 623-M's muscle-back shape keeps mass directly behind the strike for feedback and control, where a cavity spreads it to the perimeter for forgiveness.
There are 4 years between these sets (2018 and 2022), more than one design generation. Over that time irons moved toward stronger lofts, thinner and faster faces, hollow and multi-material heads and wider use of tungsten, so the newer set is not simply a better version of the older one: it may launch and spin quite differently. Here the 7-iron loft moved from 33° to 31°.
Which should you choose?
The 902-OS is the stronger-lofted set — up to 2° stronger than the 623-M on matching clubs. Expect longer carry per numbered iron but a flatter descent angle; gapping at the wedge end is where that shows up.

Frequently asked questions
Is the New Level 623-M stronger lofted than the 902-OS?
No. The 902-OS is the stronger-lofted set: its 7-iron is 31° against 33° for the New Level 623-M, 2° stronger and worth roughly 6 to 8 yards of extra carry.
What is the loft difference between the New Level 623-M and 902-OS?
At the 7-iron the difference is 2° (33° vs 31°). The largest gap on a shared club is 2° at the 4-iron, and all 7 shared clubs differ.
Which is better for higher handicap golfers, the New Level 623-M or the 902-OS?
The 902-OS. As a players distance iron it is the more forgiving design, suited to roughly 5 to 15 handicaps who want extra distance from a compact head. The New Level 623-M is a players iron, better suited to roughly scratch to 10 handicaps.
Do the New Level 623-M and 902-OS have the same lie and length?
Not exactly. At the 7-iron the New Level 623-M is 62° lie and 37 inches, the 902-OS 61.5° and 37 inches. Both can be bent or built to your own fit.
