Vortex EBR-9 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: 'subtensions measured in MRAD and remain constant at all magnifications'. Published: centre dot .2 and grid dots .2; vertical hashes 1 at whole mils and .2 at half mils; horizontal ticks .25 at half mils and .5 at whole mils; side posts from 8.5 and the bottom post from 11.5, .15 thick; ranging ladder lines .1. Drawn, not published (the sheet is to scale): crosshair .06 with an open 0.5 centre inside an illuminated broken ring 1.0 inside / 1.5 outside, four arcs from 17 to 73 degrees in each quadrant; the horizontal ticks stand ABOVE the line only, with a heavier (.15) stub BELOW, detached from the line (0.2-0.55 at odd mils, 0.2-0.7 at even); scales to 8 mil each side and 11 below; dot rows every mil from 1 to 11 below, dots at whole mils to +/-2 (rows 1-2), 3 (3-4), 4 (5-6), 5 (7-11); ranging ladder above centre with bars 0.7 / 0.9 / 1.1 / 1.5 wide at 9.1 / 9.5 / 10.0 / 10.8, numbered 6 / 5 / 4 / 3, and a 0.8 bar below it; a 0.6 tick across each post at 10. Numerals 2-8 on the horizontal scale, 10 at the post ticks, 2-10 beside the even grid rows. Posts drawn to 13.4 mil (the sheet's frame is 12.8). 9 Oct 2026: the AMG 1-10x24 FFP sheet (VTX_AMG-11002, widen id 9njx2mgllt - its file name says 1-4x24, its title 1-10x24 FFP) prints the same figures and draws the same outlines, so the AMG is listed too.

How this one was checked

Verified 8 Oct 2026 against specs/vortex/VTX_RZR-11002_EBR-9_MRAD_RS_I_RI_ST.pdf page 1. Scale 14.095 pt/mil from the half-mil tick pitch, centre (198.0, 221.102) = the red centre dot; all ten published callouts land (listed in tools/build_vortex_ebr9_mrad.py). Geometry converted exactly from the vector outlines (rectangles from each outline's own vertices), so tick sides (above-only ticks, detached stubs below), gaps and extents are the drawing's own; the squared-font numerals were separated from the marks as outline clusters that do not touch the reticle and replaced by labels; ring from its vertex radii and cut angles; dots from their bezier extents.
