Lens Quality
This is usually something shooters overlook when picking a red dot sight because it’s not very obvious until you get more experience with the sight.
The Holosun has some glass glare and reflection, especially in the dark environment.
Reticle Options
Some of the Holosun models allow the shooter to turn on or off some parts of the reticle giving the ability to have the ideal reticle for the target. The reason for it could be using the reticle for holdover estimate.
The 65 MOA reticle with a center 2 MOA is very similar to EOTech's 68 MOA reticle. In fact they are the same.
The user can cycle through 3 different settings:
- 2 MOA dot only for precise long range aiming
- 65 MOA ring only for close up target acquisition
- Combined works well with red dot magnifier
Beefy External Construction
Holosun optics are mostly made from lightweight aircraft-grade 6061 and some are with 7075 aerospace aluminum.

How Does The Solar Fail Safe Work?
The solar panel on top of the optic is another innovation by Holosun to raise the bar on red dot technology.
In addition to the 50,000 – 100,000 hours of battery life, the solar panel provides additional power source to keep the optic working even if the battery is running low.
Under day light, the solar panel works like a fiber optic.
How Long Is The Battery Life?
On average, the HoloSun series red dot sights last about 50,000 hours using just 1 CR2032 battery or 1 CR1620 battery .
Some models like HE510C, HE503GU have about 100,000 hours of battery. It definitely pushed the bar compared tp other red dot optics on the market.
