Holosun Reflex HS507C-RD X2 Details

About the 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 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).

Because of their size, HS407C, HS507C, and HS508T are great for mounting on a pistol.

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 507 is one of the model families in the Reflex series. The first number '5' in its name means that the user can switch between a 2 MOA dot; 2 MOA dot surrounded by a 32 MOA circle or a 32 MOA ring only.

About the product (HS 507C-RD X2)

Holosun 507C-RD V2 is a red dot sight of the Reflex series.

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

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.

This is the second generation of the 507 sights, hence the 'V2' next to the name. There are two main improvements from the first generation models:

the buttons for adjusting the illumination intensity are now bigger and placed horizontally;

the battery compartment has been moved from the bottom to the side, the battery standard has been changed from CR2032 to CR1632.

Main features:

  • 2 MOA dot & 2 MOA dot surrounded by a 32 MOA circle

  • compact and lightweight

  • a solar cell on top of the device

  • perfect for a pistol or a rifle

  • ShakeAwake function with the last setting recall

  • 12 illumination intensity levels - 2 of them are NV compatible

  • Parallax free

  • 50.000 hours of battery life

  • the battery compartment is on the side of the device
