HURRICANEHolo Sight - (TAN)
Beautiful full metal holographic sight is a replica of the popular military EO-tech sight. This sight is digitally adjusted and can be set to either red of green sights. Key features include:

- Red & Green dot color changeable (digitally).
- 20 level brightness adjustment.
- Low power indicator.
- 2 hours auto shut down.
- UV tempered lens.
- Moisture Resistant design.
- Battery: LR44 Alkaline button cell x 4.
- Full metal construction

Operates just like the EOTECH sight. Press the UP button and the unit turns on. Press the UP and DOWN buttons to adjust intensity, or the middle W button to change between red and green holographic pattern. Press both buttons at the same time and the unit will turn off. Perfectly designed for the M4 - install this sight onto the flat-top rail of your M4 - your M4 / M16 front sight will NOT obstruct the holographic image since its located high enough to look over the top of the front sight.
