In the second focal plane the subtensions are only true at one magnification — check your manual for which, and dial there before you hold.

Subtensions

SFP, true at 12.5x (sheet: measurements shown at highest magnification). A single fibre-optic / tritium illuminated triangle 1.5 MOA wide and 1.5 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_BAC_Triangle_Post_Reticle_TR26-C-2000105_2000106_2000107.pdf: the sheet prints exactly two dimensions, 1.5 MOA width and 1.5 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).
