The Holosun AEMS EVO is a fully enclosed rifle red dot sight that packs a big, square viewing window into a compact, sealed housing. The closed emitter shrugs off mud, rain and debris, while the wide 1.26 × 0.98 in window keeps both eyes open for fast transitions.
It runs Holosun's Multi-Reticle System (2 MOA dot / 65 MOA circle / circle-dot), Solar Failsafe and up to 50,000 hours of runtime, and ships with a lower-1/3 co-witness mount ready for AR-pattern rifles.
