Leupold Mark 4HD 2.5-10x42 FFP Riflescope: 30mm Tube, M5C3, TMR Reticle, Model 183740

Ready your rifles with a versatile Mark 4HD. We took the legendary performance of its predecessors and gave it a slimmer maintube that’s been packed full of professional-grade features. Whether you’re a dedicated enthusiast or a seasoned expert, the Mark 4HD’s optical clarity and lightweight design will get the job done at the range or in the field.

The Mark 4HD series features five magnification ranges, providing you with an accurate and reliable option for close-quarter engagements, long-range dominance, and everything in between. They’re available with a three-turn elevation dial for unmatched confidence at extreme distances, a precise ZeroLock windage adjustment that won’t budge when knocked around, and a side focus that delivers tack-sharp images as close as 25 yards. And like all Leupold riflescopes, they’re waterproof, fogproof, and backed by our lifetime guarantee.

FEATURES

• 4:1 Zoom Ratio
  A 4:1 zoom ratio strikes the perfect balance between weight and versatility, giving you plenty of magnification options without weighing you down. Model magnification ranges are available in powers of 4x: 1-4.5, 2.5-10, 4.5-18, and 8-32.
  
  
• 25-Yard Side Focus
  The 25-yard side focus allows you to adjust the scope's parallax from 25 yards to infinity, ensuring a crisp, stationary reticle at almost any distance.
  
  
• Professional-Grade Optical System
  Leupold’s Professional-Grade Optical System offers unmatched light transmission that’s designed to outperform in the most challenging lighting conditions, industry-leading glare reduction for a clear image in harsh, direct light, and the resolution and clarity that professional guides and shooters demand in the field.
  
  
• Custom BDC Dial Compatible
  Leupold's Custom Dial System® (CDS®) gives you the ability to customize your turret (adjustment dial) to your exact ballistics and environmental conditions. Once your new custom dial is installed, simply range the target, turn the dial to that number, and aim dead on.
  
  
• M5C3 ZeroLock® Adjustments
  These low-profile dials are available on select models and provide up to 30-MILs of adjustment in 3 revolutions and 0.1 MIL clicks. Visual and tactile revolution indicators ensure you don’t get lost in the travel. The ZeroLock® feature prevents inadvertent adjustments and ensures accurate return to zero.
  
  
• First Focal Plane
  In First Focal Plane (front focal plane) scopes, the reticle grows and shrinks at the same rate as the target when you adjust the magnification. This allows you to accurately use the reticle feature at any magnification setting. These reticles are ideal in tactical situations but can also aid in range estimation for hunters and target shooters.
  
  
• Zero Lock Dial
  The ZeroLock® system eliminates accidental dial movement by locking it in place.
  
  
• Waterproof, Fogproof, & Shockproof
  Leupold pioneered modern waterproof and fogproof technology using advanced internal gasses and sealing methods that withstand extreme temperatures, elevation changes, and shocks, so the internals of the optics stay moisture free and crystal clear for life.

  • Uses hash marks instead of dots for increased ranging and holdover precision
  • Provides aiming points for both wind and bullet drop compensation
  • 1 MIL is approximately 3.6 inches at 100 yards
  • Hash marks are spaced 0.5 MIL apart, transitioning to 0.2 MIL spacing on the outer edges
  • Not caliber specific
  • Front (first) focal plane
  • MIL based systems are the current military standard
