Holosun 503CU Product description
About the Holosun 503CU
Holosun 503CU is a red dot sight of the Paralow series.
The letter 'C' means that the sight features a solar panel on top – the red dot sight can work without the battery inserted when there is sufficient lighting. The letter 'U' implies that the turrets of the device are shrouded and thus protected against potential blows.
The product features the ShakeAwake function. When left powered on, the sight will go from 'active mode' to 'sleep mode' after a while to prevent unnecessary battery drain. Once moved, it will power back on immediately.

About the Holosun Paralow series
Paralow is one of the red dot sight series made by Holosun. On the outside, these small tube sights are very familiar to the Micro red dot sights made by the famous Swedish red dot sight manufacturing company. 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 503CU model family
Holosun 503 MOA red dot is one of the model families in the Paralow 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. The second number '0' implies that the product comes with standard accessories (without honeycomb filter, quick-release mount and flip-up lens covers).
Mounting details of 503CU MOA dot
These small tube sights come with a high mount for an AR platform (lower 1/3 co-witness) and a low mount for other mounting purposes (such as mounting on a rifle). All models in the Paralow series except the ones with the letter 'A' in their name have the same mounting platform as the Aimpoint Micro devices.
