The illumination is powered by a CR2032 battery. The click value for the elevation and windage adjustments is 0.5 MOA. Turret caps are secured with a wire so that the user doesn't lose them. These durable red dot sights feature a single-piece housing made out of aluminum. Altogether, there are 12 illumination intensity levels to choose from, 2 of which are NVD compatible. The battery life is 50.000 hours.
The 406 is one of the model families in the Tube series. The first number '4' in its name suggests that it features a 2 MOA dot.
Holosun 406 A is a red dot sight of the Tube series.
The letter 'A' indicates that this is the standard model. The device has the battery compartment on its right side in the form of a battery tray and lacks the solar panel.
The product features the ShakeAwake function. When left powered on, the device will go from 'active mode' to 'sleep mode' after a while to prevent unnecessary battery drain. Once moved, it will power back on immediately.
