Are Closed Emitters A Fad? | Holosun 509T
This video analyzes the Holosun 509T, a closed-emitter optic, discussing its suitability for various firearm platforms. The presenter, Brassfacts, highlights that while closed emitters offer protection from elements, their application depends on the specific use case. The 509T is deemed ideal for open-carry handguns and offset/piggyback rifle mounts due to its durability, but less so for rifles due to parallax and battery life concerns. For concealed carry, the benefits are debated against potential printing issues and the practicality of open-emitter sights.
