Holosun 507C X2 Details

About the Holosun 507C X2

Holosun 507C X2 is a red dot sight from the Reflex series.

The letter 'C' means that the MOA red dot 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 507C 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 third generation of the 507C sights, which replaced the second ‘V2’ generation. The company introduced the button lock mode, now found only on the ‘X2’ models.

The buttons have been reduced to the same size as they were originally, on the first models – Holosun made them smaller again and placed them horizontally.

But as opposed to the first 507C models, the second ‘V2’, and now the third ‘X2’ generation of these Holosun red dot sights have a side battery compartment, as it is no longer positioned on the bottom.

Main features of 507C MOA dot

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

  • green and red illumination
  • compact and lightweight

  • a Solar Failsafe™ cell on top of the device

  • perfect for a pistol

  • Shake Awake™ function with the last setting recall

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

  • Free of parallax

  • 100.000 hours of battery life

  • Side CR1632 battery compartment

About the Holosun Reflex series

Reflex is one of the red dot sight series made by Holosun. These compact red dot 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 – 512T is closed from both sides and thus bigger while 510C is a reflex-type red dot sight of a bigger design).

Because of their size, 407C, 507C, and 508T are great for mounting on a pistol.

But as opposed to the first 507C models, the second V2, and now the third X2 generation of these Holosun red dot sights have a side CR1632 battery compartment (it is no longer positioned on the bottom).. 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 'Elite' Models

The Holosun's Elite series is distinguished by having at least one of the following features – green illumination, gold illumination, and titanium housing. Offering illumination other in green and gold is a welcome upgrade for shooters who have problems seeing the red colour. Titanium has been gaining in popularity in the red dot sight market because it is strong, lightweight and more resistant to corrosion than aluminium.

About the 507C 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.

Mounting details of 507C MOA red dot

Holosun 507C has a Trijicon RMR footprint for mounting purposes.

Warranty on Holosun 507C red dot sights

The Holosun warranty is 3 years.

Delivery on time. The product is great. Good excise price of the product, kind sellers.
The instructions for use on the website are old, as well as the fact that the device uses the power supply of the "CR2032" series battery .... which is not true. It is true that it uses a "CR1632" series battery.
The official website of "Holosun" states that the accompanying battery was included in the package, and it was not in the purchased packaging.

Good first pistol rds By
I've used the HS 507C V2 mounted on an RMR cut Glock 17 for 6 months now with about 2000 rounds shot. In my experience the optic is great value for your money and searching the internet the majority of reviews will say the same.

The reticle options are a nice extra especially for less experienced dot users. Most people do eventually settle on using the simple dot.

Issues like water/snow disturbing the sight picture can be attributed to the open emitter design more than only the 507. A holster that covers the optic helps, but if you want to roll around in mud all day I'd suggest a closed emitter system.

My specific optic has the cirle dot emitter ever so slightly offset giving a tilted sight picture. This does not affect shooting in any meaningful way and is barely noticeable, but could drive someone with OCD crazy. I h

Works well By
Overall it's a good sight but has a few minor issues. The reticle is well focused, very clear, lacks any streaking unless run super bright in dim light and it can get bright enough even against snow on a sunny day. I was unable to get a good picture of the reticle, so what you see in the pics I took does not reflect how that aspect looks. The option of 3 different reticles is also very welcome. I think this is well worth the money and it functions great so far (about 1000 rounds of 22LR). I recommend it, but there is room for improvement too.
