Leupold Mark 5HD 3.6-18×44 TMR FFP Scope

The Leupold Mark 5HD TMR combines a 3.6-18x magnification range with a clean first focal plane MIL reticle and straightforward turret controls.

The TMR uses hash marks rather than traditional dots. Therefore, the reticle gives the shooter clear MIL reference points without filling the view with an overly busy grid.

Leupold pairs this reticle with its M5C3 ZeroLock elevation system. As a result, the reticle and adjustment controls use the same MIL measurement system.

The scope also uses a 35mm maintube, 44mm objective lens and side-focus control. In addition, it weighs about 26 ounces, which keeps the optic relatively light for its size and adjustment range.

Leupold Mark 5HD TMR Magnification

The Leupold Mark 5HD TMR provides magnification from 3.6x to 18x.

At 3.6x, the wider field of view helps you see more of the area around the target. Meanwhile, increasing magnification brings smaller details closer.

This 5:1 zoom range gives the scope useful flexibility without making it unnecessarily large.

The field of view measures approximately 28.3 feet at 100 yards on 3.6x and 5.8 feet at 100 yards on 18x.

TMR First Focal Plane Reticle

The TMR reticle sits in the first focal plane.

Therefore, the reticle changes apparent size as you move through the magnification range. Its MIL measurements remain proportional to the target image at different magnification settings.

This matters because the shooter does not have to use one particular magnification for the reticle measurements to stay consistent.

The layout also stays cleaner than many full-grid reticles, which may appeal to shooters who want useful reference marks without covering too much of the image.

TMR Hash Mark Design

The TMR expands on a traditional MIL-style reticle by using hash marks instead of dots.

These marks provide clear reference points for measurement and adjustment.

The main markings use 0.5 MIL spacing, while finer markings appear toward parts of the outer layout.

Because the reticle uses MIL measurements, it also matches the scope’s 0.1 MIL turret adjustments.

As a result, the reticle and adjustment system work together without requiring MIL-to-MOA conversions.

Leupold Mark 5HD TMR MIL System

The Leupold Mark 5HD TMR keeps both the reticle and turrets in MIL.

Each turret click equals 0.1 MIL.

Therefore, ten clicks equal one full MIL of adjustment.

Using one measurement system throughout the scope keeps the controls easier to follow, especially for someone already familiar with MIL-based optics.

M5C3 ZeroLock Elevation Turret

Leupold equips this Mark 5HD with the M5C3 elevation dial.

The turret adjusts in 0.1 MIL clicks and provides approximately 29 MIL of total elevation adjustment.

In addition, the dial works across three revolutions.

A visual and tactile revolution indicator helps the user keep track of the turret position. Therefore, it becomes easier to know which revolution you are on after making larger adjustments.

ZeroLock System

The ZeroLock system helps prevent accidental turret movement.

When you want the elevation dial to stay in place, the locking design reduces the chance of the setting changing through normal handling.

This can be useful when moving equipment or carrying the rifle between shooting positions.

The control remains straightforward, so you do not need to deal with a complicated locking arrangement.

ZeroStop Function

The elevation system also includes a ZeroStop.

After the zero position is set correctly, the system creates a firm stopping point when you return the dial.

Therefore, you can come back to the established starting point without turning past it.

ZeroLock and ZeroStop work together to make the elevation turret easier to keep track of.

29 MIL Elevation Range

The scope offers approximately 29 MIL of total elevation adjustment.

That gives the M5C3 turret a broad adjustment range within its compact design.

Because each click equals 0.1 MIL, small changes remain easy to understand.

The multi-revolution design also lets the dial provide more adjustment than a basic single-turn turret.

Windage Adjustment

Windage uses the same 0.1 MIL click value.

The scope provides approximately 23 MIL of total windage adjustment.

Unlike the exposed elevation turret, the windage control uses a cap. As a result, the cap helps protect the setting from accidental movement.

The windage turret also stays within the same MIL measurement system as the TMR reticle.

35mm Maintube

The Mark 5HD uses a 35mm maintube.

Therefore, the scope requires rings or a mount made specifically for a 35mm tube.

A standard 30mm or 1-inch mounting system will not fit correctly.

The larger tube also gives the internal adjustment system room for its broad elevation and windage ranges.

44mm Objective Lens

A 44mm objective lens keeps the front of the scope reasonably compact.

It works well with the 3.6-18x magnification range without adding the extra bulk of a much larger 50mm or 56mm objective.

As a result, the scope keeps a useful balance between optical size and overall dimensions.

The 44mm objective also helps the Mark 5HD maintain its relatively short profile.

Side Focus

The scope includes a side-focus control.

This control allows the shooter to adjust parallax for different target distances.

The adjustment begins at approximately 50 yards.

Because the control sits on the side of the scope, it remains easy to reach without turning the front objective.

Parallax Adjustment

Correct side-focus adjustment helps keep the reticle and target image from appearing to move in relation to each other when the shooter’s eye position changes.

Therefore, it can make the sight picture feel more stable at different distances.

The important point is to set the control for the actual target distance rather than simply leaving it in one position.

The 50-yard minimum setting gives the scope a useful starting point for this type of optic.

Eye Relief

Eye relief measures approximately 3.5 to 3.8 inches through the magnification range.

This gives some room to position the optic according to the rifle, mount and user’s natural head position.

However, the final mounting position should allow a full sight picture without forcing the shooter to move the head unnaturally.

Always check eye relief across more than one magnification setting before finalizing the mount position.

Non-Illuminated TMR Reticle

This TMR version does not use illumination.

Therefore, the scope does not require a battery for the reticle.

There is also no brightness control or illumination dial to manage.

For someone who prefers a straightforward etched reticle, this keeps the design simple.

No Battery Required

Because the TMR reticle is non-illuminated, the scope works without a battery.

This removes one maintenance item from the optic.

It also means you do not have to check battery condition before normal use.

The reticle remains visible through the optical system under suitable light conditions.

Lightweight Mark 5HD Design

The scope weighs approximately 26 ounces.

That is fairly light considering the 35mm tube, 18x maximum magnification and wide adjustment range.

The shorter body also helps prevent the scope from feeling unnecessarily bulky.

As a result, the Mark 5HD gives you a substantial adjustment system without turning into an oversized optic.

Leupold Optical System

Leupold builds the Mark 5HD optical system to provide a clear image across changing outdoor light conditions.

The lenses also work to control glare when light comes from difficult angles.

Rather than filling the page with exaggerated claims, the important point is simple: the optical system aims to keep the view clear and usable.

The 3.6-18x range also gives the user several magnification choices for different viewing distances.

Waterproof and Fogproof Design

Leupold seals the scope to help keep moisture away from the internal optical system.

Therefore, normal changes in weather and temperature should not cause internal fogging when the optic remains in proper condition.

The sealed construction also helps protect the internal parts from rain and moisture.

For cleaning and maintenance, follow Leupold’s instructions rather than opening the scope body.
