Its generous field of view maximizes situational awareness, a crucial factor whether you're engaging multiple targets quickly or scanning a vast landscape for elusive game.

Unparalleled Optical Clarity and Performance

At the heart of the Steiner M7Xi 2.9-20x50mm is an optical system crafted to deliver outstanding detail recognition and unmatched image quality. The 50mm objective lens gathers ample light, ensuring bright, high-contrast images even in challenging low-light conditions, such as dawn, dusk, or heavily overcast days. When you need to resolve fine details on distant targets, the 2.9x to 20x magnification range provides the versatility required for both wide situational awareness at lower powers and precise target identification at maximum zoom.

This superior optical clarity is essential for:

• Target Identification: Quickly and accurately distinguishing between targets and their surroundings, even against complex backgrounds.
• Impact Verification: Confirming precise shot placement for immediate follow-up adjustments.
• Environmental Reading: Observing mirage, wind flags, and other indicators to make informed ballistic corrections.

The generous exit pupil diameter, ranging from 9.20mm at 2.9x to 2.50mm at 20x, ensures that the light transmitted through the scope efficiently reaches your eye, reducing eye strain during prolonged observation and providing a bright sight picture across the entire magnification range. This optical excellence ensures that every detail, no matter how small or distant, is presented with exceptional fidelity, allowing shooters to make critical decisions with confidence.

The Game-Changing Tremor 3 Reticle: First Focal Plane Advantage

The Steiner M7Xi 2.9-20x50mm (MPN: 8717T3) is equipped with the highly sought-after Tremor 3 reticle, positioned in the first focal plane (FFP). Why is a First Focal Plane reticle crucial for long-range precision? In an FFP design, the reticle scales proportionally with the magnification. This means that your holdover points, wind dots, and milling references remain accurate and true at every magnification setting. There’s no need for mental calculations or conversions; if a target measures 2 Mils at 5x, it will still measure 2 Mils at 20x, simplifying target ranging and ballistic solutions.

The Tremor 3 reticle itself is a masterpiece of design, optimized for speed and precision. Its key features include:

• Wind Dots: A series of dots extending horizontally from the main aiming point, providing precise holdover references for various wind speeds. This allows for rapid, intuitive windage corrections without clicking turrets, ideal for dynamic shooting scenarios.
• Milling Scale: Integrated into the reticle, enabling accurate target ranging and size estimation when combined with known dimensions.
• Horizontal Ranging Stadia: Lines below the main horizontal axis assist in rapid ranging of targets of known height.
• Vertical Holdover Tree: A Christmas-tree-style design offers multiple precise hold points for elevation, allowing for quick adjustments for bullet drop across different distances without needing to adjust the elevation turret for every shot. This is especially valuable in competitions where speed is critical, or in tactical situations requiring rapid engagement.
• Uncluttered Center: The design ensures a clean and precise aiming point for minimal obstruction of the target.

For users asking "What is the best reticle for PRS competition?" or "How do I make rapid wind calls without adjusting my turrets?", the Tremor 3 reticle in the Steiner M7Xi provides a direct, highly effective solution. It empowers shooters to quickly adapt to changing conditions and engage targets with speed and confidence.

Engineered for Extreme Ruggedness and Reliability

When operating in demanding environments, the durability of your equipment is paramount. The Steiner M7Xi 2.9-20x50mm is built to withstand the harshest conditions imaginable. Its sturdy 34mm main tube, crafted from high-grade aluminum, provides exceptional structural integrity and more internal space for generous windage and elevation adjustments—essential for dialing in those extreme long shots.

The scope's construction incorporates Steiner's legendary German engineering and commitment to robust design. This means it is:

• Shockproof: Designed to absorb recoil from powerful calibers and withstand accidental drops or impacts without losing zero or compromising optical integrity.
• Waterproof: Impervious to water ingress, ensuring reliable performance even in heavy rain, snow, or submersion. This is critical for preventing internal fogging and protecting sensitive optical components.
• Fogproof: Nitrogen-purged internals prevent internal condensation and fogging, guaranteeing a clear sight picture regardless of temperature fluctuations or humidity changes.

This extreme ruggedness and reliability ensure that the Steiner M7Xi remains operational and precise when it matters most, making it the optic of choice for military and law enforcement professionals who depend on their gear in life-or-death situations, as well as hunters who face unpredictable weather, and competitive shooters who push their equipment to the limits.

Precision Adjustments for Unwavering Accuracy

Repeatable accuracy is a hallmark of any top-tier riflescope, and the Steiner M7Xi excels in this regard. The precise windage and elevation adjustment turrets offer tactile click-by-click feedback that you can both hear and feel. Each click translates to a consistent and verifiable change in the point of impact, allowing for highly accurate and repeatable zeroing and ballistic corrections. This audible and tactile feedback is invaluable, particularly when making adjustments in low light or while maintaining focus on the target.

The low-profile turrets are thoughtfully designed to provide outstanding situational awareness. Their unobtrusive nature reduces the likelihood of snagging on gear or vegetation, and they contribute to the scope's compact profile, freeing up more rail space for essential clip-on devices such as thermal imagers or night vision units. This modularity enhances the scope's versatility, providing superior operational capabilities in any combat or hunting situation, day or night.

Furthermore, the side focus parallax adjustment, ranging from 50 yards to infinity, allows for precise elimination of parallax error at various distances. This ensures that the reticle and the target remain in the same focal plane, preventing apparent reticle shift and guaranteeing consistent accuracy regardless of eye position.

Optimized for Operational Readiness and Versatility

The overall length of the Steiner M7Xi 2.9-20x50mm is a compact 13.80 inches, a design choice that significantly contributes to its operational utility. This shorter profile creates more available rail space on your rifle, which is vital for mounting clip-on devices such as:

• Thermal Imaging Devices: For target detection and engagement in complete darkness or through obscuration.
• Night Vision Devices: To extend your operational capabilities into low-light and nighttime environments.

This integrated capability means that a single rifle setup can seamlessly transition from day to night operations without extensive reconfiguration, offering unparalleled flexibility for military personnel, law enforcement, and dedicated nocturnal hunters. The generous field of view (12 - 1.78 meters at 100 meters, or approximately 36 to 5.3 feet at 100 yards) provides a wide panoramic sight picture at lower magnifications, crucial for rapidly acquiring targets and maintaining awareness of your surroundings. Even at maximum 20x magnification, the field of view remains sufficient for precision engagements.

Eye relief, crucial for shooter comfort and safety, is consistently maintained between 3.23 inches and 3.43 inches across the entire magnification range. This comfortable eye relief reduces the risk of scope bite from heavy recoiling firearms and ensures a clear, full sight picture for a wide range of shooting positions.
