HexCap — Snap-Fit Kill Flash / Anti-Reflection Device for Red Dot Sights

The HexCap is One Hundred Concepts' original invention — a rugged snap-fit killflash-style anti-reflection device (ARD) engineered to eliminate optic glare and protect your lens. Each HexCap is precision-fit for specific red dot sight models from leading brands like EOTech Trijicon Vortex Primary Arms Aimpoint Sig Sauer Holosun Leupold and Steiner.

In the 7 S’s of camouflage shine is one of the fastest ways to compromise your position. The lens of your optic is often the brightest most reflective surface on your kit — and even a split-second glint can give you away.

This isn’t theory. From WWII through modern combat countless soldiers and snipers have been spotted — and sometimes killed — because of reflections off their scopes. The HexCap was created to solve that problem. Its hexagonal honeycomb structure breaks up reflections while preserving a clear sight picture giving you both concealment and lens protection in one low-profile field-ready package.

Unlike most OEM and imitation ARD's the HexCap is lighter tougher and built for field use. It protects your glass from scratches dirt and debris while reducing signature — trusted by professionals hunters and serious shooters worldwide.
