Reflex is one of the red dot sights series made by Holosun. These red dot sights are not closed from both sides like the Tube, Infiniti and Paralow series, which results in lower mass and compact design (there are two 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). HS407C, HS507C and HS508T models from this series can also be mounted on a pistol because of their small size. Red dot sights found in this category are commonly referred to as open reflex sights.
All of the models come with the ShakeAwake function, meaning that – if the user forgets to turn the illumination off – the device will go from 'active mode' to 'sleep mode' after some time of inactivity. When the optic detects movement, it will return to 'active mode' in an instant (the dot will power back on). This function helps preserve the battery life to a great extent.
For now, there are five different models in the series. HS407 is the most basic one – it comes with a 2 MOA dot reticle. HS507C, HS508T, HS510C and HS512T allow the user to switch between a classic 2 MOA dot and a 2 MOA dot surrounded by a 32 MOA circle (circle dot). The letter C in the model name indicates that the red dot sight is solar powered (it is equipped with a solar cell). The solar-powered open reflex sights made by Holosun can work on both the solar cell and the battery or on solar cell only. All Holosun red dot sights are parallax free.
The click value of the devices is 0.5 MOA. These open reflex sight optics offer 12 illumination intensity levels – the 2 lowest settings are suitable for use with night vision devices. The devices are powered by a CR2032 battery. They boast an amazing battery life of 50.000 hours.
The warranty is 5 years on the material and 3 years on the electronics.
