The 3.8-18X44 variant has been picked for the M110 SASS while the 5-25X56 has been selected for the M22 Mod 0 sniper rifle. There is also a 7-35X56 model available for extreme long range use. All variants are available in a selection of different reticles, both illuminated and non-illuminated.

Coming in over a pound lighter than competing scopes, the Mark 5HD 5-25X56 is a versatile high performance optic. With its 5X magnification range and ample field of view, this optic is capable of clearing courses and topping podiums. Excellent light transmission and image clarity come from high quality glass and Leupold’s Professional-Grade Optical System. The 35mm main tube gives the erector system plenty space for the adjustments that demanding long range competitions require. A locking elevation turret features tactile clicks and a revolution indicator while an included power throw lever makes magnification changes smooth and fast. Like all Leupold scopes, the Mark 5HD is manufactured in America. They are waterproof, fogproof, shockproof, and guaranteed for life.

About the Tremor 3 reticle

The Tremor 3 Reticle, designed by Horus Vision, is a reticle style meant to boost the shooting efficacy of users. It maximizes speed and accuracy by implementing unique, patented features1. The reticle utilizes a MIL-based system with a grid design, offering precise aiming points for bullet drop compensation and wind2.

The TREMOR 3 reticle builds the Accuracy 1st – Speed Shooting Formula into the elevation hold, further facilitating faster shooting3. It also employs the patented Time Of Flight Wind Dots for rapid and reliable wind reading, a feature that various military units globally are adopting4.

When you move down the reticle to 10 mils, the TREMOR 3 design includes solid mil lines every 2 mils5. This formatting aids in better target engagement, allowing the shooter to make quick adjustments more effectively5.

The TREMOR 3 reticle is also deliberately designed for usage without the need to dial in windage6. This strategic configuration prevents unintentional alterations in the windage turret.

Let's delve deeper into the features of the TREMOR3™ reticle:

  • Horus Grid: This feature uses a uniform grid of 0.2 milliradians that enable the user to compensate for bullet drop under any conditions without requiring the user to hold out in space.

  • Time of Flight Wind Dots: These patented wind dots offer accurate wind holds in wind speed values to allow for quick and easy holds without a ballistic solver or needing to count numerous subtensions.

  • Highly-Refined Mil Markers: This reticle includes “Chevron” mil markers that subtend to 0.1 milliradians for accurate target range estimation.

  • Rapid Range Bars: These patented bars allow for quick estimates of the range to known size targets.

  • Moving Target Holds: These are used for targets moving at speeds up to 10 mph.
