The Holosun AEMS CORE X2 is a compact, enclosed red dot sight designed for speed and precision.

It features an advanced optical system that reduces parallax by 50%, a new lower 1/3 co-witness mount, and is backwards compatible with original AEMS mounts.

Built from 7075-T6 aluminium with an IP67 waterproof rating, it includes Shake Awake™ Technology, 50,000-hour battery life, and a large viewing window for quick target acquisition in any environment.

Compact Power. Serious Clarity. Built for Real-World Use.

The Holosun AEMS CORE X2 is an ultra-durable enclosed reflex sight designed for rapid target acquisition and enhanced situational awareness. With a green reticle that stands out in all lighting, and a low-profile, fully enclosed design, it's the ideal optic for tactical shooters, PCC users, and modern sporting rifles.

The AEMS CORE X2 takes everything shooters loved about the original AEMS and pushes it further, delivering enhanced performance in a compact, rugged design.

With an advanced optical system that reduces parallax by 50%, the CORE X2 offers faster, more accurate target acquisition — giving you the edge when split-second decisions matter.

Built from 7075-T6 aluminium and finished with MAO coating, the housing is both lightweight and incredibly tough.

The fully enclosed design, combined with an IP67 waterproof rating and 1000G vibration resistance, ensures reliable performance in the harshest environments.

At the heart of the upgrade is an all-new four-post, lower 1/3 co-witness mount, offering ideal sight height for modern shooting setups.

It’s also backwards compatible with original AEMS mounts, giving you flexibility without compromise.

The optic features a generous 1.1 × 0.87-inch window and crystal-clear multilayer reflective glass, packed into a compact body measuring just 2.48 × 1.54 × 2.63 inches and weighing only 9.8 oz.

With unlimited eye relief, parallax-free performance, and a clean 1x magnification, the sight picture is fast, clear, and intuitive.

Power is handled by a single CR2032 battery, delivering up to 50,000 hours of battery life, while 10 daylight and 2 night vision brightness settings ensure visibility in any condition.

Holosun’s signature Shake Awake™ Technology comes as standard — automatically powering down the LED when inactive, and instantly reactivating it with the slightest movement. It’s smart, seamless, and always ready when you are.
