What’s Better? Open Or Closed Optics?
This video compares Trijicon's SRO (open emitter) and HD (closed emitter) red dot sights, highlighting the trade-offs between them. The SRO offers a wider field of view and a brighter reticle, but is more susceptible to debris. The HD has a green tint and a narrower field of view but is more robust against environmental elements like snow and mud, allowing for quick clearing.
