  • Designed for Holosun 509T red dot sights
  • Minimizes downrange reflection
  • Snap-fit design for tool-free installation
  • Durable construction for field use
  • Hexagonal lattice design maintains a low profile
  • Reduces glare for viewers in front of the optic
  • One-piece Nylon polymer construction

The HexCap is constructed from a durable one-piece nylon polymer that can withstand the rigors of field use. It works by eliminating downrange reflections at 33 degrees from the viewing axis, making it easier for you to see your target. The HexCap also significantly reduces reflections to viewers directly in front of the optic, making it more difficult for others to spot your optic.
