Vortex EBR-4 MOA
Drawn to scale from Vortex’s own specification sheet, and checked mark by mark by a person. This is the same geometry Harson Ballistics draws your holdover on.
Drawn from Vortex Optics’s published specification.

Subtensions
SFP; the sheet: subtensions 'correspond to the highest magnification' (18x). The centre section is illuminated (drawn red). Published: fine line .13, centre line .27 (the illuminated centre section to 12), hashes .75 and 1.5, 1 MOA apart inside 12 and 0.5 MOA apart outside it; windage scale to 34 where the side posts start, 1.5 thick with a 3 MOA mark at 36; elevation tree to 32, bottom post at 36; tree rows 1 / 4 / 8 wide. Drawn, not published (to scale; read exactly from the vectors): a tree row at every MOA from 2 to 32 - 8 wide at every 4th MOA, 4 wide at the other even MOA INCLUDING row 2, 1 wide at odd MOA; a 0.3 MOA gap between the red centre scale (ends 12.13) and the black outer scale (starts 12.43); the upper line breaks between 32 and 36 and runs on from 36; numerals every 4 MOA on all four arms.
How this one was checked
Verified 8 Oct 2026 against specs/vortex/VTX_SE-1626_EBR-4_MOA_RS_I_RI_ST.pdf page 1. Scale 4.5434 pt/MOA fitted to the tree-row / hash pitch, centre (198.43, 221.1); every published callout then lands (listed in tools/build_vortex_ebr4_se.py). Geometry converted exactly from the vector outlines - every rectilinear ink subpath cut into rectangles from its own vertex coordinates, each rectangle one element - so rows, widths, spacing, which side of the line each mark sits (all centred), gaps and extents are the drawing's own. Numeral positions from their glyph outlines. Bars reach the sheet's frame and are run on to 40 MOA.
