Leupold Mark 5HD

Mark 5HD Configurations: 5-25x56 and 3.6-18x44

The Mark 5HD is available in two primary configurations. The 5-25x56 is the flagship long-range variant—at 25x maximum magnification with a 56mm objective, it provides the resolution and light transmission needed for precise target identification and bullet trace at 1,000+ yards. The 3.6-18x44 is a more compact variant with a lighter weight and shorter overall length, offering a useful magnification range for PRS shooters who prefer a smaller package or for hunters who want military-grade precision in a more field-practical scope. Both use the same first focal plane reticle system and M5C3 turret, ensuring holdovers remain accurate at all magnification settings.

M5C3 Elevation System: Competition-Grade Tracking

The Mark 5HD’s M5C3 elevation system is one of its most important features for precision shooting. The M5C3 provides a zero-stop function that allows return to zero after dialing elevation without counting revolutions—critical in competition where rapid stage transitions require resetting the turret quickly. It also features a locking mechanism that prevents accidental adjustment during handling. The turret produces audible and tactile clicks with consistent values across the full adjustment range, which is the basic requirement for reliable ballistic solutions at long distances. Leupold offers the Mark 5HD in MOA and MRAD turret configurations to match the shooter’s preferred measurement system.

Mark 5HD vs. Nightforce ATACR: The Premium Comparison

The Nightforce ATACR is the Mark 5HD’s most direct competitor at the premium precision scope tier. Both are mil-spec, first focal plane, 5-25x scopes with zero-stop elevation systems used in military and PRS competition. The Nightforce has a longer military qualification testing history and a larger PRS adoption base. The Leupold Mark 5HD has U.S. military procurement behind it, superb optical quality, and Leupold’s Full Lifetime Guarantee covering accidental damage—a warranty advantage Nightforce does not match. For most civilian precision shooters, either is an excellent choice. See also: Nightforce Scopes.

Mark 5HD for PRS Competition

The Mark 5HD has seen significant adoption in Precision Rifle Series competition, though it faces strong competition from Nightforce and Schmidt & Bender at the top level. Its 5-25x magnification range covers the full spectrum of PRS stages from 100-yard positional work to 1,000-yard cold bore challenges. The first focal plane TMR or H-59 reticle provides accurate holdovers for wind and elevation at all magnification levels. For PRS competitors who want a domestic option with military credentials and the Leupold warranty, the Mark 5HD is a serious choice that has won at national-level matches.

Mounting the Mark 5HD: 35mm Rings Required

The Mark 5HD uses a 35mm main tube, which requires 35mm scope rings or a 35mm cantilever mount. This is a larger tube diameter than the standard 30mm used on most hunting scopes—the larger tube provides a wider internal adjustment range, which is critical for long-range shooting where large elevation adjustments are needed. Leupold produces their own Mark 4 rings and IMS (Integrated Mount System) for the Mark 5HD. Third-party mounts from Badger Ordnance, American Defense, and Larue Tactical also produce 35mm mounts compatible with the Mark 5HD. See also: Leupold Optics.
