The 3 Tactix EED by Riton Optics is a perfect choice for handgun applications. It utilizes a closed emitter design to protect the internal components from dust, moisture, debris, and impacts. The large 21mm x 16.5mm objective lens promotes greater situational awareness and target acquisition, and a shake awake option provides optimal battery life. The 3 Tactix EED attaches to the host weapon via ACRO footprint, and ships with 2 adapter plates: (1) Glock MOS plate and (1) RMSc plate. Additionally, a top loading battery compartment allows for battery changes without removing the optic from the pistol.
