HoloSun 512C - Best Durability


Referenced IG @Sal_gunz

Why choose the 512C - The 512C is the enclosed body design of the Holosun 510C. The improved hood design gives the optic a Leupold LCO look and also protects the optic emitter from debris and moisture from entering. It does the samething the 510C does and works for all types of long guns and subguns. 

Holosun 515GM - Best Bang For The Buck

"I have tested the Holosun 515GM long enough, and it performs extremely well, and I believe this is the bang for your buck you can possibly get" - John Lovell (Former Spec Ops), Warrior Poet Society (Watch His Review Here)
Holosun 515GM

Why Must Get The HS515GM - This little tank is the closest thing to an expensive Aimpoint Micro. It checked all the boxes for being a durable mil-spec red dot, and for the price point it's the best Aimpoint Micro alternative.

Motion Activated Reticle - ShakeAwake technology activates the reticle upon sensing any movement, and it turns off to save battery when sitting at rest

Mulit-Reticle - Toggle between 65 MOA ring reticle or just a red center dot based for precision aiming & fast target acquisition

Near Infinite Battery Life - 100,000 battery hours that's long enough for you to finish 4 yrs of  school and it will still be on

Includes Flash Kill - The Honeycomb flash hider to eliminate lens glare so bad guys can't see you from far away

See Through Flip Covers - Just like the Aimpoint Pro, it protects the optic from dust, and no need to flip up the lens covers before engaging

See Through Flip Covers - Shooter can still engage with both see through lens covers closed in an emergency situation. It protects from dust and doesn't hinder the shooter

If you haven't decided on the Trijicon MRO yet, and you have been thinking for a quite a while for getting something with a large field of view in a compact optic package, for a PCC or a fighting rifle, then definitely check out HE530G on OpticsPlanet for a better deal.

Holosun HE508T - Best RMR Alternative

Side Battery Access - Access the battery from the side without removing the sight off the slide or re-zeroing required.

But there is more…

Motion Sensor Reticle - Holosun’s Shake Awake technology activates the reticle based on the last setting recall upon movement, and it turns off to save battery when at rest.

What Makes Holosun Products Great?

What makes Holosun products great is the durability and the price point!

  • Unique
  • Packed with advanced features
  • Durable
  • Affordable

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.

More 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.

For Sig Sauer has the same multiple reticle offering (Dot, Circle-Dot, Dot with Holds, Circle-Dot with Holds). All of the red dot sights offered by the two companies have 1 MOA and 2 MOA dot sizes and adjustable brightness settings.

Beefy External Construction

Holosun optics are mostly made from lightweight aircraft-grade 6061 and some are with 7075 aerospace aluminum.

But, here is something EVEN BETTER!

Holosun has introduced its unique Titanium alloy body optics to the market for providing ultra-lightweight optics, while the Titanium material is about 35% STRONGER than 7075 T6. This means a new generation of optics manufacturing has begun!

Aftermarket Mounts

Holosun's optics assemble the look and feel of Aimpoint and Trijicon products, which means most of the optics can accept mounts made for Aimpoint Pro, Aimpoint Comp, Trijicon RMR & Trijicon MRO.

Getting those high-quality mounts will ensure secure installation on the rifle and retain zero.

Mounts from LaRue, Scalarworks, American Defense, Midwest Industries, KDG are all great options to go with.


Only good things to say here. Holosun provides outstanding packaging with perfect English instructions and toolkits.
