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.
Trijicon BAC Triangle Post (AccuPoint 3-9x40) — second focal plane, MOA subtensions, 3–9×
SFP, true at 9x (sheet: measurements shown at highest magnification). A single fibre-optic / tritium illuminated triangle 2.0 MOA wide and 2.0 MOA tall, aiming point at its apex, on a black post of the same width running to the bottom of the field (drawn to 40 MOA). Illumination colour by SKU (red / amber / green). The sheet draws the post as an outline; on the scope it is solid.
How this one was checked
Verified 15 Oct 2026 against AccuPoint_Triangle_Post_Reticle_TR20_TR20R_TR20G.pdf: the sheet prints exactly two dimensions, 2.0 MOA width and 2.0 MOA height of the triangle, both represented; the post width equals the triangle base on the drawing (76.8 vs 83.5 pt outline incl. its stroke).
