7 Reasons Why the Holosun 510C is the Best Reflex Sight

 Author's Opinion: The Holosun 510C-GR ELITE is simply one of the best reflex sites on the market. Yes, this may offend a ton of fanboys because they have a bias geared towards Aimpoint or EOTech, but this is my opinion, and I have tested all of them and have a ton of time using these in the field. Sure Aimpoints and EOTechs are built well, however, the batteries in my EOTech have on more than one occasion given me some headache. My Aimpoint is built like an M1 Abrams Tank and has always worked, with the exception of "once" when the battery started to die after years of abuse and use. With this being noted in regard to my Aimpoint, I will admit it still did not fail me, but the battery took a nosedive on a hot bright sunny day. So why would I recommend a Holosun 510C-GR Elite and not another Aimpoint you might ask?


1. Cost - Best Bang for the Buck

For ONLY $339 dollars nothing at even double the price even comes close to matching it. Aimpoints, yes, are tough as tanks and have a great battery life, but in regard to cost, the Holosun 510c takes the cake.


2. Backup Solar Fail-Safe 

Yes, the Holosun 510c features a backup solar fail-safe and will power the optic if a battery failure has occurred. This feature also allows the optic to pull less energy from the battery and incorporate solar to reduce usage on the battery. This is an amazing option should a battery die. Batteries die, it is just a fact of life. 



3. Battery Life = Up to 50,000 Hours on a Single 2032 Battery

The Holosun has 50,000-hour battery life. That simply kills any EOTECH I have ever owned or used. Yes, my Aimpoint is a tank and has comparable battery life. 


4. Shake Awake Technology - Ready on the Move

When you put your Holosun 510c down it simply turns off when no movement is detected. With the slightest touch, it will turn right back on and pick up at right at your last setting. This is an excellent feature and the timing modes can be adjusted normally by holding this + button down for 5 seconds until you see the reticle flash. Check the manual for details. 


5. No Cover = SWAT Optics has a Solution

When you purchase a Holosun 510c from SWAT Optics you will receive a robust cover Made in the USA by SWAT Optics which is made out of High Impact Polycarbonate and Carbon Fiber. This Holosun 510c cover is durable and tough as nails and will provide limited protection from dust and impacts.


6. Multiple Reticle System which is also known as (MRS)

The HE510C-GR can be switched between a 65 MOA circle with 2 MOA dot, a 2 MOA dot only, or a 65 MOA ring only, all at the push of a button. My Aimpoint did not have this feature, but I really like it!

7. The Holosun Reticle Choices are Super CRISP and CLEAR

There is no starburst effect like with other high-end reflex sights. The Holosun glass and chosen reticles are clear and crisp.
