World’s first riflescope with an external thread for directly screw-mounted clip-on devices

With the world’s first integrated external thread on the objective, ALPEN OPTICS, in cooperation with Präzise Jagen, sets new standards in the connection between riflescope and clip-on technology. Instead of conventional clamping or plug-in solutions, the clip-on device is mounted directly via a precise screw connection on the riflescope – ensuring maximum stability, absolute repeatability, and reduced adapter weight.

In combination with the optional Präzise Jagen Fusion Adapter and the Präzise Jagen Duo Connector, the innovative thread system enables a play-free and permanently durable connection between the optic and the clip-on device. The direct form-fit connection creates an exceptionally robust unit that reliably withstands even strong recoil forces.

Another advantage: the compact design saves valuable space at the objective and ensures optimized weapon balance. This solution particularly excels in lightweight setups or combination firearms. At the same time, handling is noticeably improved – especially during extended use.

With this technical innovation, ALPEN OPTICS – in cooperation with Präzise Jagen – redefines the mounting of clip-on devices: more precise, more secure, and consistently practice-oriented.

Greater ease of use for maximum precision

The high-quality, rubberized adjustment elements allow precise operation even under adverse conditions. The elevation adjustment is equipped with a locking mechanism that reliably prevents accidental adjustment. In addition, the integrated Zero Stop enables a safe return to the zero position – a real advantage, especially when switching between different distances. And the throw lever speeds up magnification changes, allowing you to react in a flash in the field.

Innovative SmartDot-Technologie
MADE IN GERMANY

The integrated SmartDot technology uses a tilt sensor to conserve battery power while ensuring the riflescope is always ready for use. The illuminated dot automatically activates when the rifle is brought into the firing position and switches off again when the rifle is lowered. The illumination unit is located on the left-hand side, combined with the parallax adjustment. This automatic control of the illuminated reticle not only saves energy but also ensures faster readiness, giving you valuable time when it matters most.

Fully weatherproof and recoil resistant

Even in demanding weather conditions, the high-quality optics from ALPEN OPTICS allow you to keep your target clearly in view. Heavy rain, snow, fog, or even brief immersion in water pose no problem for this riflescope, which is waterproof up to a depth of 1 m (IPX7). The robust, sealed housing reliably protects the internal components from moisture. To ensure clear vision during extreme temperature changes, the optics are nitrogen filled, preventing internal fogging. As a true premium riflescope, the ALPEN OPTICS Apex LT is also recoil resistant up to 1,000 g for magnum calibres.

What Others Are Saying

The video addresses a common issue with clip-on adapters mounted on riflescopes: the adapter tends to slide forward under recoil and does not remain securely in place. The presenter explains why many supposed “solutions” fail to provide a lasting fix and analyzes the underlying causes of the problem – a frustrating technical challenge in real-world use for owners of clip-on systems.

Side Parallax Adjustment

Parallax compensation for perfect positioning

Simply set the parallax compensation to the desired range and the position of the reticle will remain the same. This is particularly useful if you look into the eyepiece at a slight angle, as the reticle will stay locked on your target.
Fully Multi-Coated Lenses

More light for clearer images

The optics are fully coated with a premium multi-layer coating, which increases the light transmission to up to 95% to produce stunningly bright images.
SmartDot Technology

Always spot on

Thanks to the innovative SmartDot technology with a built-in tilt sensor, the light spot switches on and off automatically based on the position of the rifle. This saves you valuable time and prevents the battery from draining.
Second Focal Plane

Second focal plane (SFP) reticle

The reticle is located in the second focal plane, and therefore does not increase in size when you zoom in. As a result, the subtension depends on the zoom level.
Fogproof

Weatherproof design

The binoculars are filled with nitrogen, which prevents the inside of the lenses from fogging up and obstructing your view during abrupt changes in temperature.
Shootproof

Premium recoil-resistant optics

This premium riflescope can withstand recoil forces of up to 1000 grams, equivalent to a Magnum caliber.
Tube Diameter 30mm

Shows your target in the right light

In general, larger tube diameters provide better light transmission. Featuring a tube diameter of 30 mm, this scope lets in plenty of light to render your target clearly.
Nitrogen Purged

Nitrogen filling

The temperature can change rapidly when you’re out in the wild. To prevent the lenses from fogging up on the inside and obstructing your view, the optics are filled with nitrogen.
Zero Stop Function

Zero stop

This riflescope is equipped with a zero stop function so that you can readjust the optics, e.g. due to a change in the wind conditions. With a correctly configured zero stop, you can return to the zero position without conducting a visual check. The zero stop prevents you from going below the zero position.
Waterproof housing

Withstands streams and heavy rain

A brief moment of inattention and the binoculars end up in a puddle. No problem – the waterproof housing reliably keeps liquids out of the optics. Even during heavy downpours, no water can penetrate the interior.
Fusion Adapter compatible

Fusion Adapter Compatible

Difference MOA andd MRAD

The MOA and MRAD turrent systems refer to two different measurement systems: metric and imperial. The Metric and the Imperial. Thus, the imperial system uses MOA and inches, and the metric system uses MRAD and centimeters. Therefore, at some point the question arises which turrent system is the better one. First and foremost, it's a matter of habit and personal preference.

MOA

MOA
MOA stands for Minute Of Angle and corresponds to 1 / 60 of a degree. The system is suitable for those familiar with the imperial system, since it is calculated in inches. 1 MOA is equivalent to 1.047'' at 100 yd (2.9 cm at 100 m).

MRAD

MRAD
MRAD stands for milliradian and is 1 / 1000 of a radian (angular measure). 0.1 MRAD / MIL is equivalent to 1 cm at 100 m and is suitable for those using the metric system. One advantage of the metric system is, that it is very easy to calculate. The shooting distance (unit meter) can be quickly converted into the unit of turret adjustment (centimeter). One click of an MRAD click adjustment thus corresponds to 3 cm (0.03 m) at a firing distance of 300 m. ALPEN Optics uses MRAD 0.1 click adjustments for all riflescopes.

Präzise Jagen Fusion Adapter for Alpen APEX LT 2–12x44 Gen 2
The new Fusion Adapter was specifically developed for the secure and precise mounting of clip-on devices onto the riflescope. Unlike the traditional clamping sleeve, the adapter is not pushed on but screwed directly onto the riflescope and secured using thread clamping. This results in an especially stable and play-free connection between the clip-on device and the optic. Mounting can be carried out on the APEX LT 2–12x44 Gen 2. Thanks to its compact design, the Fusion Adapter is particularly suitable for combination weapons or setups with very limited space at the objective lens. A major advantage is the significant weight saving compared to conventional adapter solutions. The reduced weight improves the weapon's balance, facilitates handling, and increases comfort during longer use. At the same time, the adapter is recoil-proof up to 1000G Magnum – making it perfectly suitable even for the most powerful calibres. The precisely manufactured internal thread ensures exact alignment of the adapter on the riflescope. The integrated bayonet on the front guarantees absolutely repeatable positioning with each attachment and removal. The Fusion Adapter is made from high-quality aluminium, which is reliably protected against corrosion and wear by a hard anodised coating. This combines maximum stability with a modern, lightweight design. Advantages at a glance: Screw-on system instead of clamping → extremely stable connection Significant weight saving for improved balance and handling Also ideal where space at the objective is limited (e.g. combination weapons) Recoil-proof up to 1000G Magnum Exact alignment and repeatable mounting through precision internal thread & bayonet Robust, corrosion-protected aluminium construction We explicitly point out that a clip-on device may only be mounted on a weapon if permitted by the legislation of the respective country. Mounting is carried out at your own risk and responsibility.

Product information "ALPEN OPTICS APEX LT Riflescope 2–12x44 A4 Gen 2"

The ALPEN OPTICS Apex LT 2–12x44 Gen 2 is a truly versatile riflescope for daytime and low-light hunting – and it raises the bar in every sense. The second generation of this much-loved optical instrument brings a host of meaningful improvements that make a real difference where it counts.

The world's first riflescope with an external thread for directly mounted clip-on devices

In collaboration with Präzise Jagen, ALPEN OPTICS has introduced the world's first integrated external thread on the objective lens – a genuine leap forward in how riflescopes and clip-on devices work together. Rather than relying on conventional clamping or slide-on solutions, the clip-on device threads directly onto the riflescope for a secure, precision-engineered connection that delivers outstanding stability, true return-to-zero repeatability and a lighter overall setup.

Paired with the optional Präzise Jagen Fusion Adapter and connected via the Präzise Jagen Duo Connector, the innovative thread system creates a rock-solid, play-free bond between optic and clip-on device that holds firm even under heavy recoil.

The compact design also frees up valuable space around the objective end, improving the overall balance of the firearm – a real benefit with well-balanced or combination setups. Day-to-day handling feels noticeably better too, especially during longer outings.

Together, ALPEN OPTICS and Präzise Jagen have fundamentally rethought how clip-on devices are mounted – and the result is cleaner, more reliable and built for real-world use.

Effortless precision, even under pressure

The high-quality rubberised turrets give you confident, precise adjustments in any conditions. The elevation turret features a locking mechanism to prevent accidental movement, while the integrated Zero Stop lets you return to your zero quickly and reliably – invaluable when switching between distances. The throw lever makes changing magnification fast and intuitive, so you're always ready the moment an opportunity presents itself.

Built-in flexibility

The riflescope is fully compatible with the optional ALPEN OPTICS ballistic turret (item no.: 15682), giving you straightforward custom adjustments out to 500 m. 

Proven optical performance

The riflescope features a 30 mm main tube and comes fitted with an illuminated reticle 4 (A4) in the second focal plane (SFP), meaning the reticle size remains constant regardless of magnification. Adjustments are made in clean 0.1 MRAD clicks – that's 1 cm per click at 100 m.

Engineered for the field

At just 812 g, the slim, lightweight build makes this an ideal pairing for clip-on devices, while the new external thread keeps the whole mounting process refreshingly straightforward. The rugged housing is fully recoil-proof and waterproof, ready to perform no matter what the conditions throw at it.

Outstanding lens coating

The premium FMC multi-layer coating (Fully Multi-Coated) is a hallmark of quality, delivering maximum light transmission with minimal unwanted reflections. The result is a bright, high-contrast image that stays sharp edge to edge – even when the light gets tough.

Innovative SmartDot Technology

SmartDot Technology, built directly into the riflescope, keeps battery drain to a minimum while ensuring you're always ready to shoot. A tilt sensor detects when the rifle is raised to the shoulder and switches the illuminated dot on automatically – and turns it straight off again when the rifle is lowered. The illumination unit sits on the left side of the tube, keeping everything neat and accessible.

Weatherproof and recoil-proof – without compromise

Whatever the weather, ALPEN OPTICS keeps your target in clear view. Heavy rain, snow, fog or even a brief dip in a stream are no problem – the optics are waterproof to 1 m (IPX7) and built to take it. Nitrogen purging prevents internal fogging across extreme temperature swings, and as a true premium riflescope, the ALPEN OPTICS Apex LT Gen 2 is recoil-proof up to 1,000 g Magnum calibres.
