Holosun 407K X2 Details

About the Holosun "407K" MOA red dot

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 Holosun 407C moa dot507C moa dot, and 508T dot.

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

The Holosun 407k reflex red dot features the ShakeAwake function. When left powered on, the Holosun reflex optical sight will go from 'active mode' to 'sleep mode' after a while to prevent unnecessary battery drain. Once moved, the Holosun optic will power back on immediately.

About the Holosun Reflex series

Reflex is one of the red dot sight series made by Holosun. These compact sights are not closed on both sides like the Holosun Tube, Holosun Infiniti and Holosun Paralow series, which is why they are very compact and lightweight (there are some exceptions to this in the Holosun Reflex series – 512T is closed from both sides and thus bigger while Holosun 510C optic 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 dot, 507C dot, and 508T dot. 407K red dot sight and 507K red dot sight 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 moa 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.

Nice tiny red dot By
Using it on my PDP. I was surprised how small it is. Red dot is perfect with 10 brightness optios, shake awake working instantly and 6 MOA dot is very easy to spot, but not too big.

Watch out Walther PDP users though - it will not fit any of standard walther optic plates. You either need to order custom plate for 407k/507k or use Walther plate 04 (Leupold / Shield RMS) and modify it. You need to cut off back pins and half-shorten front pins. Ten you also need to cut about 4mm from both holding screws. If you did it right, the red dot will fit perfectly.

The best red dot for a Glock By
Hi, I have tried many different red dot sights for my Glock 17 but this HS407K is the best.
It is a new sight and I did not know what kind of mount fits so I had to bye one.

When I did get it I very pleased because it was so small and light.
The best mount for Glock is Shield Sights MNT-GLK-SMS/RMS it fits fine after two modifications.
1. use 5mm drill bit and drill boath back pins
2. make new M4 threads for the screws of HS407K

Here is few pictures of my installation.
