Vortex XLR-2 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

FFP; the sheet: 'subtensions measured in MOA and remain constant at all magnifications'. The centre scales are illuminated (drawn red). Published: red line .15; top line .1; centre dot .15; red 4-MOA hashes 2; outer 2-MOA hash .75 and half-MOA .5; red marks 1 MOA apart, outer .5 apart; side posts 1.5 thick with a mark at 48; bottom post from 38; grid dots .2 and .3. Drawn, not published (the sheet is to scale; read exactly from the vectors): red (illuminated) centre scales to 16 MOA left, right and up and to 36 down, open 0.25 at the dot. Vertical red scale: centred hashes 2.0 every 4 MOA, .75 at the other even MOA, .5 at odd MOA. Horizontal red scale differs: even-MOA marks stand 0.6 above the line with a heavier (.2) stub below, detached from it, from 0.2 to 0.8 at 4-MOA marks and to 0.5 at the others; odd-MOA ticks stand ABOVE only, to 0.3. Black outer scales from 16.5 to 32 left and right and to 24 up, centred: .5 every half MOA, .75 at 2-MOA and 1.0 at 4-MOA marks; the upper line breaks between 24 and 25 and runs on; side posts start at 32.5, the bottom post (2.0 thick) at 38; posts carry a 3.0-long tick at 48. Holdover grid: a dot row every 4 MOA from 4 to 36 below centre, dots every MOA, every 4th the large one, rows widening from +/-8 (row 4) to +/-24 (rows 32, 36). Numerals 4-32 on the horizontal arms, 4-24 up, and at both ends of every grid row. The top line is drawn 0.11; the record carries the published .1. Posts drawn to 51.5 MOA (the sheet's frame is 49.1).

How this one was checked

Verified 8 Oct 2026 against specs/vortex/VTX_RZR-42201_XLR-2_MOA_RS_I_RI_ST.pdf page 1. Scale 3.6658 pt/MOA fitted to the hash pitch, centre (198.001, 221.102) = the red centre dot; every published callout then lands except one: the top line above 25, published .1, is drawn 0.11 - recorded .1 (all listed in tools/build_vortex_ffp_grids.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, gaps and extents are the drawing's own. Grid dots taken only on the grid; numerals placed from glyph outlines, text from the value of the mark they label.
