Trijicon MRAD Precision Tree (FFP, Tenmile 3-18x44)

Drawn to scale from Trijicon’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. 0.06 mrad lines, 0.06 floating centre dot with a 0.2 mrad gap (stadia start 0.1 from centre). Marks every 0.5 mrad, 0.2 tall at the half mils and 0.4 at the whole mils: horizontal +-5, vertical +4 / -4 (numerals 2 on the windage line, 2 and 4 up, 1-4 at the rows). Hold tree on rows 1-4 mrad below centre: 0.06 mrad dots every 0.2 mrad from 0.4 outward with a 0.113 mrad diamond at every whole mil, rows 1-2 ending at the diamond at +-2, rows 3-4 at +-3 (the 0.4-wide stadia hash covers the +-0.2 position). Whole reticle illuminated. Drawing compromise: diamonds are drawn as 0.113 dots.

How this one was checked

Verified 15 Oct 2026 against Tenmile_MRAD_Precision_Tree_FFP_Reticle_3000002.pdf read as vector fills (tools/trijicon_sheet.py + a dot/diamond extraction). Scale 44.8 pt/mrad from the 0.5-mrad mark pitch (22.4 pt); 75 tree dots and 20 diamonds all land on exact 0.2 / 1.0 multiples (rows 1-2: 0.4-1.8 + diamonds 1, 2; rows 3-4: 0.4-2.8 + diamonds 1-3), marks on the lattice to 0.01 mrad. Callouts mapped: 0.5 / 1 MRAD pitches, 0.2 / 0.4 mark heights (drawn 0.21 / 0.415), 0.06 line (x2, drawn 0.075), 0.2 GAP (drawn 0.09 each side), 0.06 centre dot and tree dots (drawn 0.075), 0.113 diamond (drawn 0.128), 0.3 MRAD numeral height. Sizes are the printed values where the artwork is oversize.
