Leupold Mark 4.5-14x50e Mil-Dot Illuminated Rifle Scopes
Over the last few years the interest in higher power scopes with more durability has increased among hunters. Some hunters look to these scopes to improve visual clarity at longer ranges in order to increase the range at which they can consistently make a kill shot, while others want a more rugged scope that can take a few bumps and scrapes. For decades Leupold has developed their line of tactical Mark 4 scopes that offer both a rugged scope and optical superiority. For this review we'll be taking a look a the Mark 4 lineup of scopes along with a closer look at a Mark 4 LR/T 4.5-14x50mm Illuminated Mil-Dot scope.
The Leupold Mark 4 Riflescope. Our review model is a LR/T
4.5-14x50mm with Illuminated Mil Dot reticle and M1 turrets.
The Leupold Mark 4 line is diverse with three main lines of scopes and some additional AR-style rifle focused scopes that we will not be covering at this time. Broadly the Mark 4 line is divided into the LR/T, the ER/T, and MR/T series. The LR/T features a 30mm main tube which allows for an extensive amount of adjustment in elevation and windage. The ER/T is a higher end version of the LR/T with improved optics which allows better low-light clarity at a much higher cost than the LR/T. The MR/T series is based around smaller scopes with lower magnification that are best suited on AR-style rifles.
The excellent end to end turret adjustment of 100 MOA with the LR/T allows the long range shooter to correct bullet drops of at least 50 MOA assuming the reticle was originally sighted in at the middle of the elevation adjustment. By sighting in toward the top end of the turret adjustment (and using a canted 10-20 MOA base ) it is possible to get even more of the 100 MOA geared toward the bullet drop at longer ranges. Considering that 308 Win will drop around 37" at 1000 yards (168gr Sierra Match King at 2650 fps muzzle velocity with a 300yard zero), this allows the Mark 4 LR/T to accomplish all the long range adjustment necessary without using a canted based. Magnum cartridges that drive the bullet faster will drop less at further distances and need less correction.
Both M1 turrets are marked in 1/4 MOA with 15 clicks in one
