Steiner TM3x 2.0

• 3x magnification boost: Adds practical mid-range target detail to a non-magnified red dot setup, helping the shooter identify and engage more precisely without changing the core sighting system.
• Compact rail footprint: The short overall design leaves more room on the firearm for the primary optic and other controls, which is especially useful on carbines with limited mounting space.
• Wide field of view: A field of view of 130.00 m/1000m supports faster target acquisition and easier tracking, so added magnification does not feel overly restrictive in dynamic shooting.
• Diopter adjustment: The -2/+2 diopter range helps fine-tune the image to the shooter’s eyesight, improving reticle clarity through the magnifier and reducing visual strain during longer sessions.
• Rugged all-weather construction: Waterproof, fogproof and shockproof construction, together with a working temperature range of -46°C to +63°C, makes the magnifier suitable for hard field use across changing weather and rough handling.

About the TM3x Series

The Steiner TM3x series is built as a compact magnifier line for shooters who want to extend the capability of a red dot sight without moving to a full riflescope. In Steiner’s tactical and defensive optics range, this type of product fills the gap between true 1x speed at close distance and the added target definition needed farther out. The concept is straightforward: keep the handling advantages of a fast, unmagnified sight picture, then add magnification only when the situation calls for more detail.

What defines the series is its focus on compact dimensions, rugged construction and straightforward integration with modern carbine setups. Rather than adding unnecessary bulk, the TM3x format is intended to preserve rail space and maintain a balanced rifle. Optical performance is geared toward a clear, practical image for observation and aiming support, while the housing is designed for demanding use in changing weather and hard field conditions. For professional, defensive and range applications alike, the series is aimed at users who need a magnifier that complements a red dot system instead of complicating it.

About the Steiner TM3x 2.0

The Steiner TM3x 2.0 is a 3.00 x magnifier designed to pair with a red dot sight when a shooter wants more reach and target detail from the same rifle. This makes it particularly useful on carbines set up for defensive use, training, patrol work or practical shooting, where distances can change quickly and a pure 1x sight may not always provide enough visual information. By adding magnification behind the primary optic, the TM3x 2.0 helps the shooter read targets more clearly and place shots with greater confidence at intermediate distances.

Its 25.00 mm lens diameter and 130.00 m/1000m field of view support a sight picture that remains usable and easy to work with, rather than feeling overly tunnelled. The -2/+2 diopter range is an important practical feature because it allows the image to be tuned to the user’s eyesight, improving perceived sharpness and making the red dot appear cleaner through the magnifier. An 8.50 mm exit pupil also helps maintain a forgiving viewing experience, which is valuable when shooting from less-than-ideal positions.

Mechanically, the TM3x 2.0 is built for hard use. Its waterproof, fogproof and shockproof construction supports reliable performance in rain, temperature swings and recoil-heavy environments, while the -46°C to +63°C operating range underlines its suitability for demanding outdoor conditions. At 296.00 g and with dimensions of 101.60 mm in length, 58.10 mm in width and 57.40 mm in height, it remains compact enough to fit naturally into a modern tactical optics setup without making the rifle feel unnecessarily large or front-heavy.

About Steiner

Steiner was founded by Karl Steiner in 1947 in Bayreuth, Germany, and the company remains headquartered in Bayreuth. It has long focused on optics for demanding field use, with a product range that includes binoculars, riflescopes and thermal-imaging products. Steiner equipment is used across hunting, outdoor, marine, defense and law-enforcement applications, which helps explain the brand’s emphasis on durability and dependable performance in difficult conditions.

A notable part of Steiner’s history is its early work on weather-resistant optical construction. In 1973, the company introduced binoculars with nitrogen filling to reduce internal fogging during temperature changes. Steiner has been part of Beretta Holding since August 2008, and its modern lineup continues to reflect the same practical approach: robust housings, field-oriented optical design and products intended for real use rather than display.
