Leupold makes great hunting scopes, and great glass, but they've fallen out of favor with most of the tactical/practical shooting crowd because they haven't kept up, per price, with many of the bells and whistles those folks are wanting. When guys go looking for tactical/practical scopes, they're after side focus, locking turrets, a milling reticle, 0.1mil adjustments, and first focal plane reticles, among a dozen other features individual shooters prefer. Leupold, for the money, doesn't have a lot of these features.
For a set it and forget it low zoom scope, the Leupold Mark AR 1-4x isn't a bad scope, but you could get as much scope in a different brand for $50-100 less.
