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

Drawn to scale from ZeroTech’s own specification sheet, and checked mark by mark by a person. This is the same geometry Harson Ballistics draws your holdover on.

Official: A=12 (horseshoe span), B=3 (inner gap), C=2, D=4, E=0.75 centre dot, F=0.2 thick fine, G=1.0 thick horseshoe, H=0.2 thick drop line, I=1, J=2, K=2, L=1, M=1 high, N=1.5, O=68 (lower post start), P=16 (inner to post), Q=4 post thickness, R=1 (horseshoe gap at 12 o'clock). Index lists all hosts as RAR Illuminated; spec does not state colour. Circle encoded as A=12 diameter horseshoe (open at top per R=1 gap).
Rebuilt 11 Sep 2026 from ZeroTech's RAR spec sheet at 400 dpi. Scale 28.70 px/MOA, taken from the numbered ladder (8/12/16/20/24 at 114.8 px per 4 MOA) and confirmed independently by the horizontal marks landing symmetric at exactly +/-2, 4, 8, 10, 12, 14 and 16. MEASURED: ladder marks every 2 MOA to 24, crossbars 2.02 MOA on the fours and 1.01 on the twos, numerals to the LEFT; horizontal the same split to +/-16 with nothing at +/-6 because the horseshoe occupies it; horseshoe inner radius 5.75 MOA, 12 MOA across the stroke centre-line (A=12) at 1 MOA thick (G); centre dot 0.75 (E); side posts inner ends +/-25.35; lower post from 35.4 below centre at 4.04 thick (Q=4). Horseshoe settled against the sheet's own inset: there IS a real gap at 12 o'clock, and R=1 MOA is the half-gap from the arc end to the vertical, so 2 MOA total. Measured gap 80-100 degrees. The bottom opening runs 223.7 to 316.3 degrees, symmetric about straight down, found by locating both arc terminations directly. The apparent breaks at 3 and 9 o'clock ARE the black crosshair drawn over the red, and the arc continues through them. ⚠️ This sheet is a schematic, not a to-scale illustration like Nightforce's: the ring is drawn with a 0.51 MOA stroke against a published G=1 MOA, and its inner radius measures 5.80 where A=12 implies 5.50. Angles and mark POSITIONS are reliable (the ladder and the horizontal independently agree on 28.70 px/MOA); drawn THICKNESSES are not, so the dimension table is taken as the authority for stroke and the drawing for geometry. Letters O=68, P=16 and N=1.5 relate to the post callouts and are consistent with the drawing but are not separately represented as geometry.
