About the Paralow series
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. These are compact but not as small as an open reflex sight.
About the model family
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 user cannot switch to the circle dot reticle as with models that start with number '5'). The second number '0' implies that the product comes with standard accessories (without honeycomb filter, quick-release mount and flip-up lens covers).
About the product (HS 403 B)
HS403B is a red dot sight of the Paralow series.
The letter 'B' means that the battery compartment is on the right side of the device in the form of a battery tray. Also, it doesn't run on solar power (no solar panel on top), which is why this model has buttons for the regulation of illumination intensity on the top instead of on the side.
It is a great choice not only for standard hunting rifles and AR-rifles but also shotguns, pistols, air rifles, and crossbows.
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.
Thanks to Holosun's LED technology, the battery in this small, compact red dot sight lasts up to 50.000 hours.
