Paralow is one of the red dot sight series made by Holosun. On the outside, these small tube sights are very familiar to the Micro red dot sights made by the famous Swedish red dot sight manufacturing company. The illumination is powered by a CR2032 battery. The click value for the elevation and windage adjustments is 0.5 MOA. 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 403 is one of the model families in the Paralow series. The first number '4' in its name suggests that it features a 2 MOA dot. The second number '0' implies that the product comes with standard accessories (without honeycomb filter, quick-release mount and flip-up lens covers).
HS403GL is a red dot sight of the Paralow series.
The letter 'G' means that the battery compartment of the red dot sight is on the right side of the device, under a round-shaped cover. Also, it lacks the solar panel, which is why this model has buttons for the regulation of illumination intensity on the top instead of on the side. 'L' indicates that this is a new, improved model that retained the features of the previously introduced model (with the device HS403GL, for example, symbol “L” indicates that it is an improved model of the HS403G device).
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.
