Holosun 403R Product description

About the Holosun 403R red dot

Holosun 403R is a red dot sight of the Paralow series.

The letter 'R' indicates that the device features a rotary switch for setting the illumination intensity instead of the two buttons found on most Holosun red dot sights. The switch is located next to the battery compartment, on the side of the device.

Even though this device doesn’t have ‘U’ in its name, it comes with shrouded turrets.

‘RD’ indicates that this red dot sight features red illumination.

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 403R model family

The 403 micro red dot 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).

Mounting details and footprint on 403R 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 Paralow series except the ones with the letter 'A' in their name have the same mounting platform as the Aimpoint Micro devices.
