These Leupold LR/T models – the Mark 4 10x40mm LR/T M1 and Mark 4 16x40mm LR/T M1 – are arguably the toughest, highest performing riflescopes you’ll find anywhere. It’s no surprise that the Mark 4 10x40mm LR/T M3 was chosen as the primary day optic of the U.S. Army M-24 Sniper System. The reasons why are clear.

Superior edge-to-edge sharpness – total clarity across visual field and outstanding brightness for optimal low-light capability.

Click adjustments – audible, tactile “click” windage and elevation adjustments for extreme accuracy.

Precision parallax adjustment – adjust for specific ranges from 50 yards to infinity using turret mounted focus knob, without taking your eyes off the target.

Zeroed adjustment knobs – once sighted-in, adjustment knobs can be zeroed.

30mm maintubes – the wider diameter body offers increased windage and elevation adjustment.

Solid construction – milled from one solid piece of 6061-T6 aircraft-grade aluminum, these scopes are rugged and absolutely waterproof in all conditions.

Leupold' s goal of a scope that would be ideally suited to the special needs of the military and high intensity law enforcement organizations was achieved in the creation of the Mark 4 series. The Mark 4 10x40mm LR/T M1 is not only astoundingly durable, it is optically outstanding as well. The M1's oversized adjustment knobs give the user audible and tactile confirmation of each 1/4-MOA click.

The Mark 4 10x40mm LR/T M3 features bullet drop compensation adjustments. The M3 adjustment dials are specially calibrated and interchangeable to allow bullet drop compensation. Adjustment increments of 1 MOA elevation and ½ MOA windage allow for easy adjustment, while the side parallax adjustment dial makes it possible to eliminate parallax while remaining in shooting position.

With a 30mm maintube, edge-to-edge optical sharpness and excellent low-light capability, the Mark 4 16x40mm LR/T M1 is not only astoundingly durable, it is optically outstanding as well. The M1's oversized adjustment knobs give the user audible and tactile confirmation of each 1/4-MOA click, and can be zeroed after sighting in.
