Twilight factor: 40 at 32×
Zoom ratio: 8×

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

+ 8x zoom ratio: 4-32x in a 13.4 in, 28.6 oz package
+ Parallax focuses down to 11 yd, so it also works on rimfire and airgun rifles
+ Exposed ZeroStop elevation turret with 26 mil (90 MOA) of travel and 0.1 mil clicks
+ First-focal-plane Mil-XT reticle with DigIllum illumination
+ Power Throw Lever fitted as standard

Against it, on paper

− 30 mm maintube caps travel at 26 mil elevation and 20 mil windage, less than the 34 mm ATACR's 29 mil
− 1.6 mm exit pupil at 32x, so full magnification is only usable in bright light
− 3.5 in eye relief is short for a hard-recoiling rifle
− 4.6 ft field of view at 32x makes target reacquisition slow
