Subtensions
Official per-scope sheets VTX_DAK-3902 (3-9x40) and VTX_DAK-41202 (4-12x40), identical. Published, MOA at the highest magnification (9x / 12x - the record takes each owner's own top power): the fine line runs 4.8 from centre, line .29, post .87. Drawn, not published (both other figures land on the scale fitted to the 4.8): the fine line widens to the post along a straight shoulder 0.45 long; a plain crosshair through centre. Posts drawn to 40 MOA. Reticle image shown for representation only.
How this one was checked
Verified 9 Oct 2026 against specs/vortex/VTX_DAK-3902_V-PLEX_MOA_RS_I_RI_ST.pdf page 1 (re-downloaded from the source URL the same day, byte-identical). Scale 12.901 pt/MOA fitted to the 4.8 dimension, centre (198.0, 221.102); line 0.290 and post 0.870 then land; the outline's ON-curve vertices give the shoulder (0.45); the 4-12x40 sheet's outline is vertex-for-vertex the same. Every published callout is checked in tools/build_vortex_wave2.py and lands. Checklist walked: rows and extents, hash spacing, numerals, centre element and gap, post tips, which side of the line each mark sits (all centred unless the notes say otherwise), every callout.
