Holosun 407K Red Dot Sight Details

About the Holosun Reflex Red Dot Sight series

Reflex is one of the red dot sight series made by Holosun. These compact sights are not closed on both sides like the Tube, Infiniti and Paralow series, which is why they are very compact and lightweight (there are some exceptions to this in the Holosun Reflex series – HS512T is closed from both sides and thus bigger while HS510C is a reflex-type red dot sight of a bigger design).


The Holosun 407K and Holosun 507K models are designed specifically for pistol use – these red dot sights are even more compact than 407C, 507C, and 508T models. 407K and 507K are the first Holosun red dot sights that are equipped with a central dot size of 6 MOA.

The illumination is powered by a CR1632 battery. The click value for the elevation and windage adjustments is 0.5 MOA. These durable Holosun red dot sights feature a single-piece housing made out of 7075-T 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 Holosun model family

The Holosun 407k is one of the model families in the Reflex seriesThe first number '4' in its name suggests that it features a 6 MOA central dot reticle.

About the Holosun product 

Holosun 407k is a red dot sight of the Reflex series.

The letter 'K' indicates the red dot sight's unique, miniature shape which makes it ideal for pistol use. It has a modification of the Shield RMS footprint instead of the Trijicon RMR footprint found on 407C, 507C, and 508T.

There are two large buttons for illumination control on the side of the Holosun device.

The Holosun 407k features the ShakeAwake function. When left powered on, the Holosun 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.
