Holosun Paralow HS403GL Product description

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.

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 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 GL)

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.

Main features:

comes with a low mount and a high mount for lower third co-witness on standard AR platforms

Mounting details

These small tube sights come with a high mount for an AR platform (lower 1/3 co-witness) and a low mount for other mounting purposes (such as mounting on a rifle). All models in the Paralow series except the ones with the letter 'A' in their name have the same mounting platform as the Aimpoint Micro devices.

Great

Picked this up for my dad after he complained about his dot sight flickering on and off. Got these and he loved them! Very bright light and spans for a long distance. We will be taking these with us whenever we go hunting, and it’s compactness makes it easy to just keep in our backpack just in case we need it.

Best buy

I use this sight on my AR15 and cant see any reason why I should buy an other more expensive sight. Holosun is well made, has no parallax error and works without problem. My best buy in red dots category.
