One Hundred Concepts HexCap Red Dot Sight Cover Holosun 507C

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.
