Holosun Reflex HS510C 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 510 is one of the model families in the Reflex series. The first number '5' in its name suggests that the user can switch between a 2 MOA dot and a 2 MOA dot surrounded by a 65 MOA circle. Because of its size, it is perfect for an AR platform.

About the product (HS 510 C - FDE)

Holosun 510 C - FDE is a red dot sight of the Reflex series.

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

HS510 comes with a quick-detachable mount for the Picatinny platform.

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.

Great red dot By
Great red dot for money, extremely durable. I’ hunt with this red dot in forests with highly dense bushes across north Croatia and I’ am very satisfied with this dot. And I’ cant wait to purchase another Holosun red dot for my other rifles.
