ZEISS LRP S3 636-56 ZF-MRi Reticle

Includes Free Pro Series Throw Lever and Billet Level

The ZEISS LRP S3 636-56 ZF-MRi Reticle first focal plane riflescopes provide the best-in-class total elevation travel. In the world of long-range rimfire competition, the little 22 LR cartridge is frequently pushed beyond its intended limits. In turn, the capabilities and performance of the riflescope are tested at the extreme – with a key limiting factor for many scopes being sufficient elevation travel. ZEISS LRP S3 636-56 offers the best solution for medium to extreme long-range shooting. The 6x-36x magnification range is combined with a 32 MRAD elevation turret which supports more precise shot placements.

In the world of long-range competition shooting, the goal is to easily locate and swiftly engage distant targets successfully with each shot. Easier said than done! Why? Obstacles between the shooter and the targets are vast. They can include extreme distances, where today’s, cartridges are pushed well beyond their intended limits. They may also include hidden targets, switching winds, poor and harsh lighting, sloppy field conditions, the stress of time, challenging stage barriers, and faulty handling that leads to dropped firearms – never a good thing. To overcome these obstacles, it will test every parameter of the riflescope’s capability. You may not be able to control the conditions, but you can certainly adjust for them based upon your choice of a riflescope.


ZEISS LRP S3 636-56 Features

Best-in-class total elevation travel

With a staggering amount of total elevation travel

  • 160 MOA or 46.5 MRAD for the 425-50 model
  • 110 MOA or 32 MRAD for the 636-56 model

Advanced optics

With Extra Low Dispersion (ED) glass elements, ZEISS T* multi-coated lenses, and 90% light transmission, the ZEISS LRP S3 models deliver advanced optical performance.

Ballistic Stop and External Locking Windage Turret

ZEISS LRP S3 riflescopes utilize ZEISS’ proven Ballistic Stop to provide an absolute and true return to zero. Furthermore, they offer an External Locking Windage Turret that provides immediate access for wind corrections, with a locking feature.

Daylight visible illuminated reticle

Digitally controlled diffractive reticle illumination technology delivers an exceptionally bright point of aim – regardless of the amount of incoming light – allowing you to confirm precise shot placement on target.

A clear view, whatever the weather

Sooner or later, your shooting time and bad weather will collide. This is why ZEISS developed LotuTec. A protective exterior lens coating for ZEISS optics that enables a clearer and unhindered view in all weather conditions. It helps to greatly repel rain, snow, dust, and fingerprints, and makes lens cleaning easier.

ZEISS T* Coating

ZEISS T* coating is a guarantee of the brilliant, high-contrast images­­ which you will experience above all in adverse light conditions and in the twilight. Behind it, however, there is no specific formula for building up the layers. Instead, it is a technology that is constantly adjusted to suit new glass materials and requirements, which varies from lens to lens.

Reticle ZF-MRi | Reticle 16Illuminated

The ZF-MRi smart reticle was designed with professional input from active competitors and instructors. Its purpose is to dominate at PRS and NRL matches. The milliradian (MRAD) reticle incorporates a “tree-style” primary structure with useful hash marks, dots, and reference numbers –without the clutter. The points-of-aim and holds are represented in 0.2, 0.5, and 1.0 MRAD increments; and even numbers are displayed for fast and intuitive visual reference. If winning is your goal, then the ZF-MRi reticle was made for you. Reticle Datasheet
