INTRODUCTION

STEINER is one of the largest manufacturers of high-quality optics in the world. STEINER products meet the highest standards in precision and technology. The riflescopes were developed in cooperation with international weapons experts for the particularly strict requirements of military missions all around the globe. They have been tested in harshest operating conditions by special forces in the field and proven highly successful in combat. The riflescopes from STEINER set new standards in terms of performance, quality, and reliability. They are perfectly suitable both for military missions and official operational purposes.

The latest generation of STEINER riflescopes are available with Intelligent Firing Solution (IFS). The IFS provides all relevant data in real time at any given time. The integrated ballistics calculator with environmental sensor system (temperature, atmospheric pressure, inclination, wind drift) determines the projectile's point of impact. The display provides information about leveling and the current turret setting in the field of view.

The display can be customized to user needs. All the displayed information can be easily added, moved or deactivated if needed with a smart phone or mobile app. To do so, the riflescopes with IFS are equipped with a Bluetooth interface.

The scope includes the protective lens covers and an Allen wrench.

This user manual contains all the information you need for the use and care of the riflescopes.

Any references in the text to figures and item numbers in the images are indicated in parentheses. Example: (3/4) means fig. 3, item 4.

The definitions "on the right" and "on the left" in the text are always related to the direction of fire.

The appearance of the riflescopes may differ from the illustrations in the present user manual depending on the model in use.

Important instructions concerning safe handling of the riflescope are emphasized by the warning signs CAUTION, IMPORTANT, or NOTE.

⚠️ CAUTION: Observe these notes to avoid a hazardous situation for the shooter.

⚠️ IMPORTANT: Observe these notes to avoid any damage to the riflescope.

SAFETY INSTRUCTIONS

⚠️ CAUTION: To avoid eye injury, do not look directly at the sun or bright light sources through the riflescope.

IMPORTANT: The riflescope may only be repaired by the manufacturer.

DESCRIPTION AND CONTROLS

The diopter adjustment ring (1/1 or 2/1) is used to adjust the individual reticle focus.

The magnification adjustment ring (1/2 or 2/2) is used to magnify the target.

The reticle illumination enhances the visibility of the reticle in adverse light conditions. The intensity of the illumination is adjusted with the adjustment ring (1/3 or 2/3). The adjustment ring for the illumination has 11 levels. Between each level, there is an "OFF" position, where the illumination is switched off. Levels 1 to 4 are intended for the use with attachments (e.g. image intensifiers). Levels 5 and 6 are suitable for application without attachments during the night. Levels 7 to 11 have been planned for use during daylight. In positions "0", the illumination is completely switched off. A 3-volt lithium battery (refer to technical data) is required for the illumination. The battery is located underneath the reticle illumination adjustment ring.

6 Second rotation indicator

On the M7Xi riflescopes, the adjustment ring (2/7) is used to correct the parallax. The M8Xi riflescopes are adjusted to be parallax free at 100 m.

The adjustment scale rings for elevation and windage (1/4 and 1/5 or 2/4 and 2/5) are calibrated such that one click represents 0.1 mrad (= 1 cm over 100 m). 270 clicks (M7Xi/M8Xi)) are available for elevation adjustment, and 60 clicks both to the right and to the left for windage adjustment. The adjustment can be felt and heard with audible clicks. Mechanical stops at both ends of the adjustment range serve as reference points.

A pin coming out of the housing after the first full turn of the adjustment scale ring for elevation (1/4 or 2/4) serves as Second rotation indicator (1/6 or 2/6). In this way, a perceptible control of the elevation adjustment is possible.

MOUNTING

Mounting the riflescope on the weapon requires 34-mm rings. High-quality, rugged rings and bases made from steel are recommended. For shots aimed at very distant targets, where the entire elevation adjustment range (26 mrad or 27 mrad) must be used, mounting with a forward tilt of 45 MOA (13.1 mrad) is recommended. Observe the manufacturer's mounting instructions.

MOUNTING AND ZEROING IN

This riflescope is shipped from the factory with the optical center (knob at '0' position) set below center. Without tapered bases the initial sight-in will likely produce an initial point of impact considerably high. For best results, Steiner recommends a 40 MOA canted base.

Instructions for mounting & zeroing M7Xi and M8Xi

Mount 0 MOA on the weapon, rail inclined 30 MOA:

• Mount the riflescope (check the torque of the mount manufacturer)
  • Zero in at 100 m (0 at approx. 48 clicks)
• Set the turrets mechanically to -0 (see page 8, point 2 (5/1 and 5/2)).
  • The scope is then ready for use

Instructions for mounting & zeroing M7Xi IFS (see IFS manual for illustrations)

Mount 0 MOA on the weapon, rail inclined 30 MOA

• Mount IFS (check torque of mount manufacturer)
  • Zero in at 100 m (0 at approx. 48 clicks)
• Set the turrets mechanically to 0 (see page 8, point 2 (5/1 and 5/2)).
• Insert battery
• Switch on IFS
• Briefly press the on/off button to electronically confirm the zero position of the turrets.
• Then program ammunition data (muzzle velocity, ballistics data, etc.) via the Steiner IFS App.

• The IFS is now ready for use

OPERATION

Adjusting image sharpness and magnification

CAUTION: Do not point riflescope at the sun or at bright light sources.

1. Point riflescope toward the sky or at a bright wall and look through it. If the reticle appears sharp and black, no further adjustment is required.
2. If necessary, turn diopter adjustment ring until the reticle appears sharp and black.
3. Adjust the desired size in the first image plane of the reticle with the magnification adjustment ring.

Adjusting windage and elevation deviation - adjustment of zero position

The zero position and the elevation and windage adjustment can be customized.

1. Sight-in the riflescope at the desired distance (e.g. 100 m).
2. Release the two adjustment screws (3/1 and 3/2) on the adjustment scale ring for elevation half a turn with the included Allen wrench.

The scale ring can now be turned without click stops.

IMPORTANT: Do not release the adjustment screws any further. Otherwise, the turret may be accidentally removed.

1. Turn scale ring to "0".

2. Tighten the adjustment screws.

3. Release the two adjustment screws (3/3 and 3/4) on the adjustment scale ring for windage half a turn with the included Allen wrench. The scale ring can now be turned without click stops.

Illustration 3

IMPORTANT: Do not release the adjustment screws any further. Otherwise, the turret may be accidentally removed.

1. Turn scale ring to "0".
2. Tighten the adjustment screws.

Adjusting reticle illumination

1. Adjust the desired illumination level with the reticle illumination adjustment ring.
2. Turn the adjustment ring to the position (4/1) between the adjusted and the next value to switch the reticle illumination off.

Illustration 4

Adjusting parallax and focus

1. Turn adjustment ring (5/2) until the number that approximately matches the distance to the target is aligned with the reference mark (5/1). If the distance is not known, turn adjustment ring until the target appears sharp.

Illustration 5

NOTE: The value adjusted on the scale of the adjustment ring does not match the actual distance. These values are approximate values, that may vary depending on the eye.

The riflescope is adjusted to be parallax-free if you can move the eye to the sides, up and/or down, without any movement of the reticle in relation to the target.

ACCESSORIES

Only use original STEINER accessories. STEINER offers a wide selection of accessories. Riflescopes with 50-mm and 56-mm objective lenses are suitable for the attachment of anti-reflective devices, sun shields, filters, and other accessories.

Replacing battery of the reticle illumination

1. Unscrew cap (6/1).
2. Take battery out and replace with new battery (refer to technical data).
3. Screw cap (6/1) on.
