Holosun's HE509T-RD X2 is an enclosed-emitter reflex sight with a titanium housing that keeps dust, rain and debris off the emitter. Its Multi-Reticle System switches between a 2 MOA dot, a 32 MOA circle or both together. Solar Failsafe keeps it running when the battery is low, Shake Awake turns the reticle on with movement, and the CR1632 battery loads from the side without removing the optic.
