What makes the Leupold Mark 4HD 4.5-18x52 ideal for precise long-range shooting and tactical applications?

This riflescope features a First Focal Plane (FFP) Illuminated PR1-MIL reticle that scales with magnification for accurate holdovers at any power. It also boasts M5C3 ZeroLock® turrets with precise 0.1 MIL click adjustments, 10 MIL per revolution, and up to 36 MIL of total elevation travel, ensuring exceptional precision.

Is this riflescope durable enough for use in challenging Australian outdoor conditions?

Yes, the Leupold Mark 4HD is built with rugged construction, making it fully waterproof, fogproof, and shockproof. Its Professional-Grade Optical System also ensures elite light transmission and glare reduction, performing reliably in diverse and extreme field conditions, including the Australian bush and outback.

How does the illuminated reticle function and what is its power source?

The illuminated PR1-MIL reticle provides daylight-bright red illumination for enhanced visibility. To conserve battery life, it incorporates Motion Sensor Technology (MST™) which automatically deactivates the illumination after 5 minutes of inactivity and instantly reactivates upon movement. It is powered by a single standard CR2032 coin-cell battery.

What type of mounting rings are compatible with the Leupold Mark 4HD 4.5-18x52 riflescope?

This riflescope features a 34mm maintube, so it requires 34mm mounting rings. We recommend considering options such as the Leupold LE175120 Backcountry Rings or the Leupold LE174074 QRW2 Quick Release Weaver Style Rings, depending on your specific rifle and mounting preference.

What kind of local support or warranty is available for this Leupold riflescope in Australia?

Australian buyers benefit from Leupold’s legendary lifetime guarantee, which ensures long-term peace of mind. This warranty is fully supported locally by authorized Australian distributors and repair centers, providing convenient access to service if ever needed.

Who It Is For:

The Leupold Mark 4HD 4.5-18x52 is designed for precision rifle shooters, PRS competitors, and tactical law enforcement professionals who require absolute reliability and precise tracking. It is also an excellent choice for Australian open-country hunters who need to dial for elevation at extended distances. Because it is powered internally by a standard CR2032 battery, it does not connect to mains power, making 240V SAA/RCM electrical safety certifications and Australian plug configurations non-applicable. Additionally, the lack of active wireless transmitters means no ACMA telecommunications licensing is required. Australian buyers can purchase with confidence knowing that local support is available through authorized Australian distributors and service centers.
