Hammy3DPrints Killflash Hex ARD for EOTech 512/552 – Forest Green

Overview

Meet the Killflash Hex Anti-Reflection Device (ARD) in forest green, designed to pair with EOTech 512 and 552 holographic sights. The friction-fit design sits compactly on the front end of the optic, delivering a secure seat that may require a firm press to install. This accessory aims to minimize reflections while preserving a clear sight picture, offering a practical upgrade for varied lighting conditions without changing the core aiming experience.

Crafted to support real-world use, the Hex ARD emphasizes both function and compatibility. Its geometric hex/honeycomb pattern is visible up close, but it remains discreet at typical viewing distances. The result is a subtle enhancement that helps manage light without dominating the lens or distracting the eye during engagement or training drills.

Key Benefits

• Secure, friction-fit attachment for EOTech 512/552 optics.
• Reduces glare and reflections at the objective end of the sight for crisper targets.
• Hex/honeycomb pattern that stays unobtrusive during live-fire or training scenarios.
• PETG-CF material delivers greater heat tolerance than standard filaments.
• Original design crafted in St. Louis, Missouri by Hammy3DPrints.

Materials & Durability

The ARD is produced with carbon fiber reinforced PETG (PETG-CF), chosen to withstand higher temperatures and demanding field conditions compared with common filaments. The forest green finish complements tactical setups, while the compact form preserves overall sight geometry. If you notice a slight shine from printing, a light sanding or a thin coat of paint can help minimize it without affecting performance.

Usage Tips

• For best results, shoot with both eyes open and keep focus on the target to minimize perceived disruption from the hex pattern.
• If the surface shows light reflectivity, consider a gentle sanding or spray coating to reduce shine while maintaining fit and function.

The Killflash Hex ARD for EOTech 512/552 in forest green offers a compact, purpose-built upgrade that can help manage glare and preserve sight geometry. It’s a practical accessory that stays out of the way while you maintain target awareness in varying lighting conditions.
