Hammy3DPrints Killflash Hex ARD for EOTech 512/552 – Anti-Reflection Device, Black

Meet the Hammy3DPrints Killflash Hex ARD, a friction fit anti reflection device designed to attach to the end of an EOTech 512 or 552 optic. Built to reduce glare at the objective end while preserving target visibility, this accessory blends practical engineering with field ready materials. The result is a compact add-on that supports rapid target acquisition without bulky changes to your sight picture.

What sets the Hex ARD apart is its hex honeycomb surface. In real world light, the pattern helps minimize reflections without overpowering what you’re aiming at. The effect is subtle in daylight and remains comfortable when you keep both eyes open and stay focused on the target. This approach helps you maintain awareness of your surroundings while you work toward a precise sight picture.

Key benefits and how it helps

• Friction fit design provides a secure end cap for the EOTech optic, staying in place under normal use.
• Reduces glare and reflections from the objective glass, which can improve perceived clarity in bright conditions.
• Hex honeycomb pattern minimizes visual disruption while keeping the target area readable.
• PETG CF material offers improved heat resistance and durability over standard filaments, enabling longer field use.
• Original design crafted in the heart of America by Hammy3DPrints, built with attention to practical performance.

Care and usage tips help you get the most from this ARD. If you notice a bit of shine on the exterior from the printing process, a quick light sanding or a thin spray finish can help minimize it. For best results, aim with both eyes open and maintain steady focus on the target to preserve situational awareness throughout your shot sequence.

Materials, fit, and field readiness

The Killflash Hex ARD uses PETG CF for enhanced durability and temperature tolerance, making it a practical option for varying environments. The design centers the device securely on the optic and is intended for real-world use, from range days to field scenarios where a compact glare shield can make a difference in perceived clarity.
