Twilight factor: 41 at 30×
Zoom ratio: 5.5×

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

+ First focal plane SCR 2 MIL reticle, so holdovers are correct at every magnification
+ Zero Click Stop turrets: dial back to zero without counting clicks
+ Illumination in both red and green, 11 levels each
+ 34 mm tube with 26 MIL of elevation travel, enough to dial a .308 or 6.5 Creedmoor past 1,000 yd from a 20 MOA base
+ Side focus down to 20 yd, so it also covers NRL22-style close targets
+ 3.5-4 in eye relief is a forgiving box for a 30x scope

Against it, on paper

− 31.4 oz and 15.16 in: a 2 lb optic before rings, not a carry-hunting scope
− Windage travel is only 15 MIL, well under the 26 MIL of elevation
− 5.5x bottom end limits it to open-country use with no low-power option for close shots
