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.

Against it, on paper

− MOA only: no MIL reticle or turret option is offered
− No zero stop is listed, so returning to zero after dialing means counting 20 MOA revolutions
− Non-illuminated reticle, a handicap at last light against dark backgrounds
− Eye relief runs 86-100 mm (3.39-3.94 in), on the short side for a hard-kicking hunting rifle
