Neither of those two have clicks. The VX-I is marked for 1/4 inch adjustments, while the rifleman is 1/2 inch. Though, not being clicks it does not matter. The rifleman has a different power ring adjustment, and the VX-I has slightly better coatings. Optically, they are both good, having generous amounts of eye relief, and superiour quality optics when compared to an Elite or Grand Slam, in my opinion that is.
