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.
Drawn from Trijicon, Inc.’s published specification.
In the second focal plane the subtensions are only true at one magnification — check your manual for which, and dial there before you hold.
SFP, true at 15x (sheet: '1 DIV = 0.5@15X, 0.75@10X, 1.5@5X, 3@2.5X'). Floating 0.06 mrad centre dot with a 0.5 mrad gap (stadia start 0.25 from centre). 0.035 mrad lines; marks every 0.5 mrad, 0.2 tall at the half mils and 0.4 at the whole mils; horizontal +-10, vertical +2 / -10; numerals 2-10 below the horizontal line and left of the vertical. Whole reticle illuminated (red LED).
Verified 15 Oct 2026 against Trijicon's dimension sheet Credo_MRAD_Center_Dot_Reticle_2900034.pdf read as vector fills (tools/trijicon_sheet.py). Scale 25.70 pt/mrad from the 0.5-mrad mark pitch (12.85 pt, 40 horizontal + 24 vertical marks all on the lattice to 0.01 mrad); the 10 MRAD, 2 MRAD, 0.5 MRAD (gap), 1 MRAD and 0.5 MRAD (pitch) dimension lines all close at that scale. Drawn sizes agree with every callout: marks 0.206 / 0.406 (0.2 / 0.4, centred on the line), line 0.041 (0.035), dot 0.066 (0.06). The 2.5-15x56 sheet (2900036) measures the same at 25.68 pt/mrad.
