Extremely short design and adjustable over a wide range of 0.5 - 3.0mm
The fixed-seat iris works with individually pin-located tempered spring steel leaves.
The aim-point is precisely maintained through a wider range of adjustment by the introduction of a new system of aperture control, which is operated by varying the pressure of a steel tube against the central aiming ring - this guarantees a perfect circle at any point within the scale.
Iris made of hardened spring steel, not brass like other manufacturers, therefore extremely robust, making it also suitable for large calibres.
Iris blades are firmly connected to the base body, therefore a shift in the point of impact is completely impossible!
Light reflection is kept to a minimum by applying a special matt finish to all external and internal surfaces.
Laser engraved indications.
Thread M9.5x1 for all well-known target rifle brands.

The Gehmann 590B Biathlon Rear Sight is a precision-engineered competition sight designed specifically for the demanding conditions of biathlon shooting. Combining rugged durability with highly controlled adjustment mechanics, it delivers reliable performance in cold, fast-paced, and high-stress race environments.
A spring-assisted vertical and lateral adjustment system ensures smooth, repeatable sight changes while improving shock resistance during movement and recoil. The result is consistent performance even under the most challenging competition conditions.
Engineered for biathlon precision, the 590B features an exceptionally fine adjustment resolution of 0.04mm per click, equating to approximately 0.8 incline at 20 clicks. At 50 metres, this corresponds to a 3mm point of impact shift per click, providing the accuracy required for both standing and prone stages.
The sight is designed with a wide effective adjustment range:
Standing position: 115mm total aiming area
Prone position: 45mm total aiming area
Built for durability and long service life, the 590B incorporates larger, stable spindles that reduce internal abrasion and wear over time. This ensures smooth operation and consistent adjustment precision throughout extended use.
A longer flap lever improves ease of handling, while the precisely engineered protective flap helps prevent the ingress of snow and water, making it ideal for winter competition environments.
Large, knurled windage and elevation knobs allow for fast, accurate adjustment even when wearing gloves. Integrated scale markings on the knobs and a reference line on the sight body allow shooters to quickly verify settings at a glance.
Constructed from lightweight yet durable aluminium, the 590B offers an optimal balance between stability and weight efficiency. Its robust dovetail clamp system ensures a secure and stable fit across all popular biathlon rifles. The Gehmann 590B Biathlon Rear Sight is built for elite-level winter competition, offering precision, durability, and reliability when every shot counts.
The Gehmann 590-L 'Compact' Rear Sight has been developed specifically to meet the needs of left-handed target shooters, offering exceptional precision, quality and value in a compact, competition-ready design. Created in response to the limited availability of affordable left-hand rear sights, the 590-L combines robust construction with refined adjustment capabilities, making it an ideal choice for both club and competitive shooters.
Designed to comply with modern I.S.S.F. scoring requirements, the 590-L features finer click adjustments, providing a bullet shift of just 0.8mm at 50 metres and 0.16mm at 10 metres. These precise adjustments allow shooters to make small, repeatable corrections for maximum scoring accuracy under decimal scoring systems.
The windage adjustment knob is positioned on the opposite side to the standard 590 model, making adjustments far more convenient for left-handed shooters, while still allowing the sight to be used comfortably by both left- and right-handed competitors. Manufactured from high-quality solid aluminium with a durable matt black anti-reflection finish, the 590-L offers long-lasting reliability and a professional appearance.
Its compact mounting design provides maximum adjustment travel, ensuring excellent compatibility with a wide range of rear sight irises without compromising positioning or eye relief.
