Key Features
Optical System
- The 3.6-18x magnification range provides a broad field of view at lower power while delivering sufficient detail for precise target identification at 18x. The 44mm objective lens integrates ample light gathering capability, contributing to consistent image clarity under varying conditions.
- The integrated PR1-MIL illuminated reticle offers distinct holdover and windage references, enhancing target acquisition in varied light conditions and against complex backgrounds. Reticle illumination can be adjusted to match ambient light, mitigating washout or excessive glare and preserving the shooter’s natural night vision.
Mechanical Adjustments
- This Leupold optic incorporates robust M5C3 ZeroLock turrets, which provide precise, repeatable adjustments with tactile and audible clicks. The ZeroLock feature ensures turrets remain locked against accidental rotation, maintaining the established zero under dynamic conditions. A multi-turn indicator confirms elevation adjustments without requiring the shooter to divert attention from the target, facilitating rapid and accurate adjustments.
Construction & Durability
- Constructed from aircraft-grade aluminum, the Mark 5HD is designed for resilience and sustained performance. It is nitrogen purged for fogproof operation and is fully waterproof, ensuring reliability as critical shooting range equipment and a dependable component of tactical optics kits in challenging environments. This scope is a critical firearm accessory for those who prioritize repeatable accuracy and robust field performance.
