[LEUPOLD]Mark 4HD 2.5-10x42 M5C3 FFP Illum. TMR

The Mark 4HD is a versatile riflescope.
While inheriting the legendary performance of the previous model,
It features a slimmer main tube and professional features.
From shooting hobbyists to experienced shooters,
The Mark 4HD's high optical performance and lightweight design allow
It demonstrates its capabilities both at the shooting range and in actual combat.

The Mark 4HD series offers five different magnification ranges:
From quick response at close range to accurate shooting at long range,
It can be used in a wide range of situations.
This scope is equipped with a height adjustment dial that allows for three full rotations of adjustment.
It supports accurate shooting even at extreme distances.
In addition, the ZeroLock wind direction adjustment function means you don't have to worry about the settings shifting even if it receives an impact.
It features side focus for clear images even at close ranges of up to 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.

・M5C3 ZeroLock Adjustments
The M5C3 ZeroLock adjustment system provides precise and reliable click adjustment.

・FFP/ First Focal Plane
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.

TMR
mil scale for measuring distance
The reticle has evenly spaced mil (mrad) scales.
It can be used to measure the distance to a target. The scale is divided into 0.2 mil increments, allowing for high accuracy.

Ballistic correction design
The scale allows for accurate corrections when the target is far away or in windy conditions.

Simple and highly visible structure
The design eliminates unnecessary elements, making it easier to focus on the target and allowing for quicker aiming.
