The Holosun AEMS EVO Red Dot Sight (AEMS-EVO-RD) is an enclosed-emitter rifle red dot sight with Holosun's Multi-Reticle System — a 2 MOA red dot, a 65 MOA circle, or both as a circle-dot — behind a large 1.26 × 0.98 in (32 × 25 mm) window, weighing 3.9 oz (111 g) and supplied with a lower-1/3 co-witness mount.
The square, wide window is the point of the AEMS design: it keeps both eyes open and makes target transitions quick. Red is the most widely used emitter colour and the most economical on battery. The sealed emitter shrugs off mud, rain and debris, and Solar Failsafe backs a CR2032 cell rated for up to 50,000 hours. The housing is IPX8 rated for water immersion.
How It Compares
The same sight is offered as the AEMS EVO green dot sight and the AEMS EVO gold dot sight. Step up to the AEMS PRO X2 red dot sight for a larger window and a forward-facing light sensor, or down to the AEMS CORE X2 red dot sight for a simpler single-dot sight without the Multi-Reticle System. For a much smaller enclosed option see the AEMS Micro red dot sight. Browse all enclosed red dot sights and straight-pull rifle optics, or read our guide to choosing an optic for an AR-pattern rifle.
Ideal For
- Civilian Service Rifle and practical rifle shooting on straight-pull AR-pattern carbines
- Practical shotgun and 3-Gun stages, where the wide window makes target pick-up fast
- All-weather work on the hill and in the rain, where a sealed emitter cannot be blocked
- Airsoft skirmishing and training rifles that need a rugged, weatherproof sight

Frequently Asked Questions
What reticles does the Holosun AEMS EVO Red Dot Sight offer?
The Holosun AEMS EVO Red Dot Sight uses Holosun's Multi-Reticle System, which switches between a 2 MOA red dot on its own, a 65 MOA circle on its own, and both together as a circle-dot.
Will the Holosun AEMS EVO co-witness with AR-pattern iron sights?
Yes. The Holosun AEMS EVO is supplied with a lower-1/3 co-witness mount, which sits the reticle high enough that standard AR-height iron sights appear in the lower third of the window.
What battery does the Holosun AEMS EVO take and how long does it last?
The Holosun AEMS EVO runs on a single CR2032 coin cell and is rated for up to 50,000 hours. Solar Failsafe supplements the cell in daylight and will keep the sight running if the battery fails.
Is the Holosun AEMS EVO an enclosed red dot sight?
Yes, the Holosun AEMS EVO uses a fully enclosed emitter and the housing is rated IPX8 for water immersion, so mud, rain and debris cannot reach the emitter and block the reticle.
How does the AEMS EVO differ from the AEMS PRO X2?
The AEMS EVO is the streamlined enclosed model with a 1.26 × 0.98 in (32 × 25 mm) window. The AEMS PRO X2 has a larger window and adds a forward-facing light sensor, which reads the light in front of the shooter rather than above the sight.
Is the Holosun AEMS EVO night-vision compatible?
Yes. The Holosun AEMS EVO has 12 brightness settings, of which 10 are daylight settings and 2 are night-vision compatible, so the reticle can be dimmed far enough to use behind a night vision device.
