Subtensions
ZeroTech PHR spec sheet, 2.5-15 column. Fixed dimensions: A=5 MOA centre cross, B=0.16, C=1.1, D=5 (fine stroke starts), E=10 (post starts), F/G/H=15/20/25 MOA hold bars, I/J/K=5/7.5/12 MOA bar widths, P=10 vertical post, Q=3.5 centre upper arm. Variable for this scope: L=0.80 post, M=0.24 fine line, N=0.16 bar, O=0.24 centre cross. SFP, true at 15x.
How this one was checked
Verified 14 Sep 2026 against ZeroTech's own PHR spec sheet (resources.zerotechoptics.com/images/reticleManuals/phr-specs.pdf) by reading the PDF's vector shapes with pymupdf. GEOMETRY, confirmed against the drawing's own vectors. Scale 7.448 pt/MOA, taken from the widest hold bar, whose 89.38 pt matches the published K=12 MOA exactly; the post's inner tip then lands at 10.0 MOA, which is the published E. Structure on every arm: a thin centre cross, a gap, a fine stroke from 5 to 10 MOA, then the post. The three hold bars sit below centre at the published F=15, G=20 and H=25 MOA (drawn 15.45, 20.28 and 25.18, about two per cent long, so the published figures are used) and are I=5, J=7.5 and K=12 MOA wide (drawn 5.58, 7.65 and 12.00). THE RECORD WAS MISSING ITS FINE AIMING STROKE: the sheet draws it from 5 to 10 MOA on all four arms - measured -10.06..-5.10 and +5.05..+10.01 - and it was absent, exactly as on the PHR3 records. P=10 MOA is the vertical post's start, matching the horizontal E. Q=3.5 MOA is the centre cross's upper arm, drawn at 3.47. WEIGHTS come from the sheet's variable table, 2.5-15 column, not from the art: the drawing is the 6-24 variant, as its post measures 0.530 MOA against that column's L=0.50 and its fine stroke 0.158 against M=0.16. This scope's four weights are therefore read straight off its own published column.
