It can be used in a wide range of situations.
This series is equipped with a height adjustment dial that can be adjusted by three turns,
It can be used with great confidence even at extreme distances.
In addition, it has a ZeroLock wind direction adjustment function that prevents the settings from shifting even when subjected to impact,
It also features a side focus feature that provides clear images from close range of 25 yards (approximately 22.9 meters).

A common feature of all Leupold scopes is that they are waterproof and fog-proof, allowing for long-term use with peace of mind.

・4:1 Zoom Ratio
The 4:1 zoom ratio allows for a wide range of shooting situations, from close range to long range.

・25-Yard Side Focus
It is equipped with a side focus function that allows parallax adjustment from 25 yards (approximately 22.9 meters).

・Professional-Grade Optical System
The professional-grade optical system provides excellent light transmission and high resolution, ensuring a clear view even in low or strong light conditions.

・Motion Sensor Technology (MST)
Motion sensor technology automatically turns off illumination if the scope is not used for a certain period of time, extending battery life.

・M5C3 ZeroLock® Adjustments
The M5C3 ZeroLock® adjustment system prevents accidental adjustment and provides precise, reliable click adjustments.

First Focal Plane
The First Focal Plane (FFP) design keeps the reticle scale constant as magnification changes, allowing for precise distance measurement and ballistic correction.

・Electronic Reticle Level
The electronic reticle level function allows you to accurately check the horizontal alignment of the scope, improving shooting accuracy.

・Illuminated
It is equipped with an illumination function, making the reticle easier to see even in dimly lit environments.

・Nightvision Compatible Illumination
Night vision compatible illumination makes it suitable for use in conjunction with night vision devices.

・Waterproof, Fogproof, & Shockproof
Waterproof, fog-proof, and shock-resistant, it's reliable even in harsh environments.

FFP
Reticle size changes when magnification is changed
In FFP, increasing the magnification causes the reticle to expand, and decreasing the magnification causes it to shrink.
This ensures that the reticle graduations (mils or MOA) always remain accurately scaled at any magnification.

Easy distance measurement and correction
Use the reticle scale to measure the distance of the target,
When correcting for wind direction or trajectory, you get accurate information regardless of magnification.

Ideal for long-range shooting
When shooting at long-distance targets or in situations where the effects of wind and gravity need to be taken into account,
FFP scopes offer high accuracy.

PR1-MIL
Simple and intuitive design
The minimum necessary scale is used, achieving both ease of viewing and operability.
This helps the shooter focus on the target.

Precision mill scale
The 0.1 mil graduations allow for quick distance measurement and ballistic corrections.
It is also ideal for wind direction correction.

First focal plane (FFP) compatible
Even if you change the magnification, the scale of the scale does not change,
Accurate measurements and corrections are possible at any magnification.

Versatile
Not just for long-range shooting and target shooting,
It is also suitable for tactical situations.
