The Holosun AEMS CORE X2 Red is a compact enclosed red dot built for rifles that want a clean, wide sight picture without a lot of extra fuss. It runs a crisp 2 MOA red dot that’s quick to pick up, and the large window makes it easy to stay on target while moving or scanning. The enclosed design keeps the emitter protected from dirt, rain, and knocks, so it’s more “grab and go” than something you need to baby. You also get shake-awake and long battery life, so it’s ready when you are without constant adjustments. Built from tough 7075 aluminum with a lower 1/3 co-witness mount included, it’s basically a simple, rugged rifle optic with modern features baked in.

DESCRIPTION

The Holosun 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.
