Description
The Leupold Mark 4HD 8-32×56 Illum MIL is item 188486, the illuminated PR2-MIL version of the highest-magnification scope in this line. It is the lit twin of one we already carry unlit, and one of five 8-32×56 bodies on the shelf.
Which of the five 8-32×56 scopes this is
All five share a 34 mm tube, a 56 mm objective, first focal plane glass, side focus to 25 yards, 30 ounces and 15.6 inches. Turret, reticle and illumination are the only variables.
This one is the M5C3 turret clicking in 0.1 MIL with an illuminated PR2-MIL reticle. Item 183970 is the same scope unlit. Item 188485 is the illuminated M1C3 in 1/4 MOA with a PR2-MOA, item 183969 is that one unlit, and item 183971 carries a PR3-MIL.
Choose the units first. The Leupold Mark 4HD 8-32×56 Illum MIL has a mil reticle and mil turrets, so a correction you read off the glass is dialled without conversion. A mil reticle over MOA turrets is how people lose shots.
The illumination
Eight brightness settings run from a CR2032 through a push button, rated 1600 hours on low, 1000 on medium and 300 on high. The manufacturer rates the illumination daylight bright.
On a first focal plane scope at 8x, a PR2 grid is fine enough that a lit centre earns its price at the edges of the day. That is the argument for this over the unlit version, which is otherwise identical.
Night vision compatibility is not published for this item, and neither is a motion sensor row. An absent row is not a stated answer, so confirm with Leupold before planning around a clip-on device.
Magnification bought at the cost of travel
This scope publishes 20 MIL, or 70 MOA, of total elevation and 13 MIL, or 45 MOA, of windage. The mechanically smaller 6-24×52 in the same family publishes 36 MIL and 18 MIL. More magnification, less dial.
Both axes move 10 MIL per revolution. The elevation dial travel limit is published as the phrase Total Scope Travel rather than a number, on every 8-32×56 in the line, where each other Mark 4HD gives a figure.
Plan on a canted base if you intend to reach a long way, and centre your zero at the mounting stage, because 13 mils of windage is not much when the wind gets up at distance.
Turrets, parallax and glass
Elevation is the M5C3: locking, with a revolution indicator and a set screw rezero. Windage is a zero-lock turret. Precision side focus adjusts parallax down to a 25 yard minimum.
Field of view is 13.1 feet at 8x and 3.4 feet at 32x, per 100 yards. Eye relief is published at 4.2 inches at low magnification and 3.9 at high, which runs backwards against most of the range.
Mount the Leupold Mark 4HD 8-32×56 Illum MIL so that 3.9 inches is what you actually have at 32x with your normal cheek weld, rather than setting it up at 8x and hoping.
Honest notes
Worth knowing if you shop by photograph: the manufacturer page for this item serves gallery images that belong to 188483 and 188484, which are 6-24×52 scopes, not 8-32×56. Use the item number rather than the pictures to confirm what you are buying.
No BDC dial is included and the scope is not Custom Dial System compatible, though the turret is published as custom BDC dial compatible. Illumination means a battery: the etched reticle survives a dead cell, the lit centre does not.
At 30 ounces plus 34 mm rings this is a bench, bipod or F-class optic. No finish colour, coating list or light transmission figure is published, so we print none of the three.
Who this scope suits
Competitors and long-range shooters working in mils who want a lit reticle for first and last light, and anyone calling their own impacts at magnification. The Leupold Mark 4HD 8-32×56 Illum MIL is waterproof, fogproof and backed by the lifetime guarantee.
Skip it if you think in MOA, if you would rather not carry a battery, or if you need elevation range more than magnification.
