The Ultimate Anti-Reflection Device for EOTech Optics

When running an EOTech holographic sight, staying concealed can be just as important as having a clear sight picture. That’s where the EOtech HWS ARD (Anti-Reflection Device) comes in. Designed specifically for EOTech optics, this accessory is a game-changer for shooters who want to maintain stealth without sacrificing performance. Similar to a killflash, but with major improvements, the HWS ARD combines durability, protection, and advanced anti-reflective technology in a low-profile, American-made package.

Our team at Covert Arms is going to break it down.

What Is a Killflash?

A killflash, sometimes referred to as a honeycomb filter, is a device that sits over the front of a rifle optic. Its honeycomb-like design prevents sunlight or artificial light from reflecting off the optic’s glass—an issue that can easily give away a shooter’s position and make them a target. Killflashes have long been used by military and law enforcement professionals because even the slightest glint off an optic can alert an opponent or target.

What Is an Anti-Reflection Device (ARD)?

An anti-reflection device (ARD) is a modern evolution of the killflash. While traditional killflashes rely heavily on a mesh or honeycomb insert, an ARD uses advanced anti-reflective materials and specialized coatings to minimize glare even more effectively. This makes them crucial for:

• Concealment: Preventing enemy detection caused by optic glint.

• Tactical Advantage: Keeping the shooter hidden in both bright daylight and artificial lighting conditions.

• Optic Protection: Acting as a barrier against debris, paint rounds, or airsoft BBs without interfering with sight clarity.

The HWS ARD for EOTech optics delivers all of these benefits in a streamlined, easy-to-use design.

Why the EOtech HWS ARD Stands Out

Unlike generic or 3D-printed killflash alternatives, the HWS ARD is purpose-built for EOTech holographic sights. It clips directly into the optic internally, creating a secure, one-piece system that won’t rattle, shift, or snag. Removal is just as quick and effortless, so you can adapt on the fly.

Key Advantages Over Traditional Killflashes

• No Glint: Thanks to its anti-reflective material, the HWS ARD eliminates the shine that often comes with cheaper or homemade solutions.

• Low Profile: It won’t bulk up your optic or obstruct your field of view.

• Built to Last: Made in America, the HWS ARD is designed to withstand the rigors of live fire, training scenarios, and force-on-force drills.

• Impact Protection: Not just for stealth, it also shields your EOTech lens from paint marking rounds, airsoft BBs, and debris—extending the life of your optic.

Perfect for Tactical, Training, and Airsoft Use

Whether you’re a law enforcement professional, military operator, competitive shooter, or airsoft enthusiast, the HWS ARD provides a critical edge. Its stealth-enhancing design ensures you remain undetected, while its rugged build gives peace of mind that your expensive EOTech optic is protected.

Final Verdict

If you rely on your EOTech for accuracy and tactical advantage, the HWS ARD is one of the most important accessories you can add. More than just a killflash, it’s a modern, purpose-built anti-reflection device that enhances concealment, improves durability, and ensures your optic stays protected in any environment.
