Holosun 403C Product description

About the Holosun 403C sight

HOlosun 403C is a red dot sight of the Paralow series.

The letter 'C' means that the sight features a solar panel on top – the red dot sight can work without the battery inserted when there is sufficient lighting.

Does Holosun 403C have Shake Awake?

Holosun 403C features the ShakeAwake function. When left powered on, the 403C will go from 'active mode' to 'sleep mode' after a while to prevent unnecessary battery drain. Once moved, it will power back on immediately.

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 403C model family

The 403C is one of the model families in the Holosun 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).

Mounting details of 403C dot sight

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 Holosun Paralow series except the ones with the letter 'A' in their name have the same mounting platform as the Aimpoint Micro devices.

For more information about Aimpoint Micro standard read our article Footprints/Mounting Standards on Red Dot Sights or read Holosun 403C Footprint blog post.

Warranty on Holosun 403C sight

The warranty on 403C is 3 years on the material and 3 years on the electronics.

Small and great

This small red dot surprised me completely, since I did not expect such a high level of quality in a product of this price range. It is build solid and the finish is very nice. It has not parallax error that I could notice and the dot is bright enough even for day time use at the brightest sun light. I will put these dots on all my rifles. Optics Trade service and communication was also splendid.
