Zoom ratio: 3×

Exit pupil and twilight factor are computed from the published magnification and objective diameter, not measured. Real exit pupil is also capped by the erector at low magnification, and coatings and glass quality move low-light performance in ways the formula cannot see — read these as comparisons between layouts, not verdicts on scopes.

For it, on paper

+ Dead-Hold BDC hash marks give holdover and windage references without touching the turrets
+ 14.8 oz and 12.2 in on a 1 in tube
+ 3.8 in of eye relief
+ 60 MOA of elevation and windage travel

Against it, on paper

− Fixed 100 yd parallax: the image softens and parallax error grows inside 50 yd
− Second focal plane, so the BDC holds are only true at 9x
− No illumination on this reticle; the V-Brite version adds it for 1.2 oz and $50 more
