The glass on the Mark AR is good at its price point, it is lighter than any competitive scope with similar features, well-constructed (failures are practically unheard of), it has a very useful reticle for its intended purpose of shooting primarily inside three hundred yards with an extended range capability largely depending on dialing with the turrets. Those turrets are mrad calibrated, very precise and repeatable, and match the reticle.
The "big thing" about this scope is the combination of light weight and the incredible motion-activated full noon daylight bright capable Firedot illumination. No one beats the weight or that Firedot illumination. The motion-activation means you leave it on 24/7/365. It is always ready like an Aimpoint with a battery life that you will measure in years. The system is identical to that in my VX-R Patrol other than your dot is green, mine red. I'm well beyond three years on the original battery and thinking of replacing it "just because" like Aimpoint users do every few years, rather than waiting for it to eventually fail.
It's an incredible scope at its price point. The only criticism is that it does not go down to "true" 1x. I think that is an exaggerated benefit. Most low cost 1x scopes have a lot of distracting fish eye distortion at 1x. Leupold was wise to not try that at this price point. Some will criticize the 2.5 mil spacing on the hash marks in the reticle as being too widely spaced. But the reticle was designed for a different purpose: Get on target rapidly at close to medium range, and to track and engage moving targets out to 300 yards where hold overs are not needed and 4x is sufficient. Beyond that either use the turrets or know the yardage values for the hold over reticle subtensions.
I opted for the Patrol only because I hunt and shoot in low light dawn and dusk. The Patrol has better glass for those more demanding conditions. Otherwise, the Mark AR would have been fine and saved me money.
