Vortex EBR-7D MRAD

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.

In the first focal plane the subtensions hold true at every magnification, so a hold is a hold wherever the zoom ring sits.

Subtensions

FFP; the sheet: 'subtensions measured in MRAD and remain constant at all magnifications'. The centre scales are illuminated (drawn red). Published: centre dot .045, grid dots .07 and .12, top line .04, side and bottom lines .05, side/top lines start at 10.1 and the bottom line at 10.5, whole-mil hash .4, red tenth hash .15, outer tenth tick .125 and half-mil tick .175 from the axis, red marks .2 apart and outer marks .1 apart. Drawn, not published (the drawing is to scale; read exactly from the vectors): red (illuminated) centre scales to 6 mil left, right and up and to 10 mil down, open 0.1 at the centre dot. Vertical red scale: centred .4 hashes at whole mils, .15 at every 0.2 mil. Horizontal red scale is NOT the same: whole-mil hashes run from 0.2 above to 0.2 below with the lower half heavier (.05), half-mil ticks hang BELOW only to 0.15 (heavier outer part), and the 0.2-mil ticks stand ABOVE only to 0.125. Black outer scales from 6.1 to 10 mil left, right and up: .4 at whole mils, half-mil ticks on ONE side only (below the horizontal, left of the vertical) and tenth ticks ALTERNATING sides; lines from 10.1 (side, top) and 10.5 (bottom) run to the frame. Holdover grid: a dot row at every mil from 1 to 10 below centre, dots every 0.2 mil, the whole-mil dots the large ones, rows widening from +/-2 mil (rows 1-2) by 1 mil every two rows to +/-6 (rows 9-10). Numerals 2-10 on the horizontal arms, 2 / 4 / 6 up, and 2-10 beside the even grid rows. Lines drawn to 12.97 mil (past the sheet's 12.35 frame).

How this one was checked

Verified 8 Oct 2026 against specs/vortex/VTX_RZR-42402_EBR-7D_MRAD_RS_I_ST.pdf page 1. Scale 14.5725 pt/mil fitted to the outermost hashes, centre (198.0, 221.1) = the red centre dot; every published callout then lands (listed in tools/build_vortex_ebr7d.py). Geometry converted exactly from the vector outlines - every rectilinear ink subpath cut into rectangles from its own vertex coordinates, one element each - so rows, widths, spacing, which side of the line each tick sits (outer tenths alternate, half-mil / 1-MOA ticks one-sided), gaps and extents are the drawing's own. Grid dots taken only on the grid (numeral loops rejected); numeral positions from their glyph outlines, text from the value of the mark they label.
