Holosun Introduces Advanced AEMS PRO X2 and CORE X2 Red Dot Sights
Author: Aleksa M. | Publish Date: Jul 26, 2025 | Fact checked by: Marko Lalovic
Holosun has expanded its acclaimed AEMS (Advanced Enclosed Micro Sight) lineup with two innovative optics: the AEMS PRO X2 and AEMS CORE X2. These cutting-edge red dot sights represent the latest evolution in compact optics technology, engineered to deliver exceptional performance for tactical professionals, competitive shooters, and hunting enthusiasts alike.
Universal Design Features
Both models in the X2 series share several core characteristics that establish their foundation for superior performance. The sight window measures 1.1 x 0.87 inches, providing shooters with an expansive viewing area that enhances target acquisition speed while maintaining situational awareness. This generous window size creates an unobstructed field of view that proves invaluable in dynamic shooting situations.
The adjustment system on both models delivers precise zeroing capabilities with 50 MOA of travel in both windage and elevation directions. Each click produces a reliable 0.5 MOA adjustment, allowing for fine-tuning accuracy across various distances and conditions. This level of precision ensures consistent point of impact regardless of environmental factors or shooting positions.
Power Management and Battery Technology
Energy efficiency remains a critical consideration in modern optics design, and both X2 models address this through advanced power management systems. Operating on a single CR2032 battery, these sights incorporate Holosun's proven Shake Awake Technology, which automatically activates the reticle upon detecting movement and enters sleep mode during periods of inactivity.
The Last Setting Recall feature ensures that when the optic powers on, it returns to the previously selected brightness level, eliminating the need for constant readjustment. Under optimal conditions, users can expect up to 50,000 hours of continuous operation, making these sights ideal for extended deployments or long-term storage scenarios.
AEMS CORE X2: Streamlined Performance
Compact Construction and Durability
The AEMS CORE X2 represents the more streamlined option in the X2 series, featuring a minimalist design that prioritizes essential functionality without unnecessary complexity. Its compact profile makes it particularly suitable for applications where weight and space constraints are primary concerns.

Construction utilizes robust materials engineered to withstand harsh environmental conditions. The optic carries an IP67 rating, indicating complete protection against dust ingress and resistance to water immersion up to one meter for 30 minutes. This level of environmental protection ensures reliable operation in adverse weather conditions, from desert dust storms to tropical downpours.
Reticle Options and Brightness Settings
The CORE X2 features a crisp 2 MOA dot reticle available in three distinct colors: red, green, and gold. This color variety allows shooters to select the optimal reticle for their specific environment and visual preferences. Red works well in most conditions, green offers advantages in bright daylight or for users with red-green color vision variations, while gold provides excellent visibility against varied backgrounds.
Brightness control encompasses 10 daylight settings and 2 dedicated night vision settings, ensuring proper reticle visibility across the full spectrum of lighting conditions. The daylight settings range from subtle visibility for bright sunny conditions to maximum intensity for challenging lighting scenarios.
Mounting System
The included skeletonized riser facilitates straightforward installation on standard Picatinny rail systems. This design reduces weight while maintaining structural integrity, and the skeletonized pattern provides multiple mounting points for accessories or backup iron sights. The quick-detach mechanism enables rapid installation and removal without tools, supporting tactical applications where optic swapping might be necessary.
AEMS PRO X2: Enhanced Capabilities
Advanced Reticle System
The AEMS PRO X2 distinguishes itself through the inclusion of Holosun's Multi Reticle System, providing shooters with three distinct reticle options within a single optic. Users can select between a precise 2 MOA dot for accuracy-focused applications, a 65 MOA circle for rapid target acquisition, or a combination of both elements.
The 65 MOA circle proves particularly valuable for close-quarters engagements or hunting scenarios where quick target acquisition takes precedence over precision. The combined reticle offers the benefits of both configurations, with the large circle drawing the eye to the target area while the central dot provides the precise aiming point for accurate shot placement.

Superior Environmental Protection
Construction of the PRO X2 utilizes 7075 T6 aluminum, a premium aerospace-grade material known for its exceptional strength-to-weight ratio and corrosion resistance. This material choice ensures long-term durability even under extreme conditions while keeping overall weight to a minimum.
The IPX8 certification represents the highest level of water resistance available in consumer optics, indicating the sight can withstand continuous submersion beyond one meter. This rating makes the PRO X2 suitable for maritime applications, extreme weather conditions, or any scenario where complete water protection is essential.
Enhanced Power and Brightness Control
The PRO X2 incorporates Solar FailSafe technology, which automatically supplements battery power with solar energy when ambient light conditions permit. This feature extends battery life significantly and provides backup power should the primary battery fail during critical moments.
Brightness adjustment options include eight daylight settings and four night vision compatible settings. This expanded range provides more precise control over reticle visibility, allowing shooters to optimize the sight picture for specific conditions without over-illumination or insufficient brightness.
Protective Features
A flip-down lens cover with integrated anti-reflection device comes standard with the PRO X2. This cover protects the front lens from scratches, debris, and impact damage during transport and storage. The anti-reflection coating reduces glare and light signature, particularly valuable for tactical applications where concealment is important.
The flip-down design allows for instant deployment without removing the cover entirely, ensuring protection remains available when needed while providing immediate access to the sight picture during dynamic situations.
Applications and Use Cases
Both X2 models excel in diverse shooting disciplines and operational environments. The CORE X2's streamlined design makes it ideal for competitive shooting sports, hunting applications, and situations where simplicity and reliability are paramount. Its compact profile works well on carbines, pistol-caliber carbines, and shotguns where space is limited.
The PRO X2's advanced features make it particularly suitable for tactical applications, professional use, and scenarios requiring maximum versatility. The multiple reticle options and enhanced environmental protection address the demanding requirements of military, law enforcement, and serious civilian users who need one optic capable of handling diverse mission profiles.
Technical Excellence in Compact Form
The AEMS X2 series represents Holosun's commitment to advancing red dot sight technology while maintaining the reliability and value that has established the company's reputation. Both models deliver professional-grade performance in compact packages that complement modern firearms without adding excessive weight or bulk.
Whether selecting the streamlined CORE X2 or the feature-rich PRO X2, shooters gain access to optics that combine proven reliability with innovative features designed to enhance performance across a wide range of applications. These sights continue Holosun's tradition of delivering advanced technology at accessible price points, making professional-quality optics available to a broader range of users than traditional premium brands.
