The Cyelee CAT EDG is a fully enclosed red dot built for demanding conditions and hard use. Its sealed housing is waterproof, fog-proof, and dust-proof, protecting the LED and electronics from rain, mud, sand, and impact. The enclosed design is drop-tested from a six-foot drop, optic-down on concrete with a full-size pistol.The CAT EDG is machined from aircraft-grade aluminum and filled with clean gas to prevent fogging in any weather. It fits slides and plates using RMSc and k-Footprint cuts and offers a wide, clear window for fast target acquisition. Motion Deactivated Standby and a 50,000-hour battery life keep it operational across daily carry, range use, and duty applications.
