Leupold Mark 4HD 2.5-10X42 M5C3 Riflescope

Precision Revamp: The Marksman's Companion - Second Focal Plane - Illuminated TMR Reticle

Imagine standing on the firing line with breath steadily held and focus clear; at that precise moment, an optic is required that goes beyond simply serving its function and becomes an extension of user will. At that time, Leupold Mark 4HD 2.5-10 Scope with its American engineering provides the confidence to take the first shot and then the second.

Mark 4HD scopes are rich in heritage. Born from SODOM-selected optics but refined for civilian life use, these statement pieces whisper of long range days, impossible shots, and quiet assurance in knowing you can always count on your equipment - more than simply hitting targets but pushing beyond their potential limits.

Features and Benefits:

• M5C3 Zerolock elevation adjustment: Delivers precision with its generous 24-MIL range to offer both accuracy and versatility. 
• Professional-Grade System Optical: HD lenses that absorb light to provide crystal-clear images regardless of weather conditions.
• Second Focal Plane:  Often thought of as easier to learn and more familiar
• Illuminated Reticle: Capturing that perfect shot may not always occur under ideal lighting conditions. With an illuminated reticle, shooting can still take place even under less-than-ideal circumstances.
• 4X Zoom (2.5-10X), A sweet spot that combines optical excellence with versatility.

Mark 4HD goes beyond specs; it represents an approach. Leupold engineers did not merely install features with hopes that something would stick; each element was chosen carefully and planned with intention.

Consider Leupold's 4X zoom ratio; while not designed as the highest available ratio, Leupold has achieved optical perfection and versatility by concentrating on this range. An optical that understands its purpose perfectly!

The TMR reticle on the second focal plane is an excellent example of a cleverly designed reticle that is simple to understand.  When zoomed-in your aim remains clear without being obscured by obstructions in aiming. MIL-based and aligning with current military standards - however, it should feel equally at home in both competitive shooting scenarios as in combat ones.

Mark 4HD lenses excel optically. HD lenses go beyond mere marketing hype - they deliver results. Fighting light scattering to achieve crisp clarity; and offering edge-to-edge sharpness so remarkable you'll forget you're viewing through a scope altogether!

The M5C3 ZeroLock strikes the perfect balance between precision and practicality. Boasting 0.1 MIL clicks over 24.7-MIL range, this zero lock allows for pinpoint accuracy when dialing in extreme long range shots without compromising your ability to return reliably to zero. Each click provides pleasing tactile feedback confirming adjustments made.

Durability has always been at the core of our DNA. The main 30mm tube boasts durability, resilience and versatility.  Designed to withstand recoil while withstanding any elements it encounters, and keeping zero as tight as a drum.  30mm provides a wide variety of mounting options, as this tube diameter has been used for over two decades.

Leupold Mark 4HD optics are an exceptional example of American innovation when it comes to optics. Instead of trying to cater to all shooters equally, this gun excels within its niche; providing durability, clarity, and precision unrivaled by any other gun currently available on the market today. As such, it makes an excellent choice for those who seek excellence without making concessions in performance or durability.

Comparative Insights:  Mark 4HD verses the Mark 5HD

• Versus Older Mark 4 Models: The Mark 4HD introduces advancements in optical clarity, turret precision, and a more streamlined main tube packed with professional-grade features.

• Versus Mark 5HD: Instead of using a 35mm maintube, like the Mark 5HD, the Mark 4HD opts for a more streamlined design, but offers the same level of performance. This design choice allows for compatibility with a broader range of mounts.  

The Mark 5HD, with its 35mm tube, represents Leupold's top-tier offering with best-in-class coatings and military-grade durability. In contrast, the Mark 4HD, with its 30mm tube, provides a balance of performance and versatility, suitable for a wide range of applications.

The Mark 4HD's coatings and construction are designed to meet the needs of both professional and recreational users, offering high performance in a variety of conditions.  For a mid-range scope, Leupold is pushing the standard 42mm objective to its optical limits which results in better light transmission and image clarity.

Finally, there is a cost to the manufacturer in every step up in zoom factor to keep the consistency of image correct. By limiting the zoom factor to 4:1, Leupold achieves some cost savings and while still fielding a wide range for a mid-range magnification scope (2.5-10x) and including HD glass for great image resolution.

Comparative Insights:  Mark 4HD in SFP compared to FFP

In a Second Focal Plane scope like the Leupold Mark 4HD with Illuminated TMR reticle, the reticle is positioned behind the magnification lenses. This means the reticle appears the same size regardless of the magnification setting. In contrast, a First Focal Plane scope has the reticle in front of the magnification lenses, causing the reticle to grow or shrink as you adjust magnification.

Reasons a buyer might opt for the Mark 4HD with SFP over an FFP variant:

1. Clearer sight picture at high magnification: The SFP reticle remains thin and precise even at maximum zoom, potentially obscuring less of the target. This can be particularly beneficial for precise shot placement at long ranges.
2. Simpler rangefinding at a specific magnification: With SFP, rangefinding calculations are typically done at maximum magnification. Some shooters find this more straightforward, as they can memorize one set of values for use at a specific power setting.
3. Familiarity: Many shooters, especially those transitioning from traditional hunting scopes, are more accustomed to SFP scopes. This familiarity can make the transition to a high-end optic like the Mark 4HD more intuitive for some users.

While FFP scopes offer the advantage of consistent holdovers and ranging at all magnifications, the SFP design of the Mark 4HD caters to shooters who prioritize a clean sight picture at high magnifications and are comfortable performing ballistic calculations at a specific power setting. This makes the SFP Mark 4HD particularly appealing for precision long-range shooting where targets are typically engaged at higher magnifications and a fine aiming point is crucial.

It's important to note that the choice between SFP and FFP often comes down to personal preference, shooting style, and specific use cases. The Leupold Mark 4HD in SFP configuration offers a blend of traditional scope functionality with advanced features, appealing to shooters who value precision and clarity in their long-range optics.

TMR Reticle Highlights

• An open center with fine aiming dot prevents obscuring the target at long range
• Uses hash marks instead of dots for increased ranging and holdover precision
• Provides aiming points for both wind and bullet drop compensation
• Hash marks are spaced 0.5 MIL apart, transitioning to 0.2 MIL spacing on the outer edges
• Not caliber specific
• Second (rear) focal plane
• Reticle scaled for highest magnification
• MIL based systems are the current military standard
