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
- + 30 MIL of total elevation travel in a 34 mm tube at a $499.99 list price
- + Japanese ED glass with an illuminated FFP reticle and AZS zero stop
- + Choice of VHR or VPR reticle, each in MIL or MOA with matching turrets
Against it, on paper
- − 36.6 oz: heavy for a 6-24x50, a bench or PRS scope rather than a mountain-rifle scope
- − Side focus stops at 25 yd, ruling out close-range rimfire or airgun use
- − 6x bottom end and a 20.9 ft field of view at 100 yd make it a poor fit for close or fast shooting
