Holosun HS515C Review – Military Grade

Holosun Military Grade HS515C


The most important as well as an intriguing factor within this red dot sight is its optics. To start with, it has a 20mm diameter window size for a good enough wide-field view. The image you get is guaranteed to be clear, bright, and crisp.

Further, the sight has a Multiple Reticle System. It has two kinds of reticles that you can easily shift from based on your needs and preferences. The 2 MOA center dot reticle is the best fit for precision shooting. But if you are up for fats target acquisition then the 65 MOA circle dot outer ring will serve you best. How to shift between these two modes? It is very simple. Long press on the minus push button of the brightness settings and you can alter between the two types of reticles swiftly.


These Holosun optics make use of easy and effective means for adjusting your device to the needed target range. The magnification here is 1x and thus the question of adjusting that does not come into play. The windage and elevation capped turrets are easy to adjust and precise. The windage adjustment knob is at the right-hand side while the elevation adjustment knob is comfortably fitted into the top of the sight.

Also, zeroing in of the sight was simple even if the product was factory adjustment to an approximate of zero. It holds zero perfectly as well. Further, the Holosun 515C is parallax free and has unlimited eye relief. This way you need not worry about distortions in target or even make a fuss about safety while shooting. Red eyes won’t get anywhere near you!


This Holosun HS515C sight is essentially compact and lightweight. The dimensions of the device follow an order of 2.44 x 1.77 x 1.37 inches. It weight around 7 oz. Hence it is the perfect optic for a handy shooting and for comfortably carrying it around with you. No wonder the military and police prefer this one!

In terms of its structure, the sight has a strong build. Made of 7075 Aluminium and possessing a hard-anodized finish, the device guarantees you unbeatable structural durability. The snag-free housing design further guarantees the durability of all its internal organs. Further, the Holosun HS515C is waterproof.


Another unique feature of this Holosun HS515C is its battery feature or its power supply to be more accurate. The device makes use of two means of power usage and similarly operates on two modes of brightness based on the former settings. Too confused? I’ll break it down to you.

The sight has two kinds of power supply – solar power and battery generated. The solar panel fitted on the top of the device ensures the best and optimum usage of external sunlight to run the device. This is especially useful when you have drained your in-house battery and need external support. But, this feature will obviously not work in low lit conditions. Thus to make, night-time, and low light shooting plausible, the device has a battery-powered option as well. This ensures a good working for a range between 20,000 to 50,000 hours. Now, that’s a great deal!

So how do these two options determine your brightness? There are basically 2 modes – auto mode and manual mode. Auto mode will essentially run of external power and adjusts the target viewing brightness in accordance with the external environment. If the external lighting does not provide ambient light to the device then the sight starts to draw from the battery immediately.

Basically, you need not know a thing about all this, and yet you can rest assured that your shot will be bright and clear. Why would you ever want to go beyond this convenience and set to manual mode, I do not understand. Yet, within the manual mode, you will have to customize the brightness settings according to your own will. You will have the option of choosing between 10 daylight and 2-night vision brightness settings. A kill-flash feature is also included to optimize your view.

To save battery consumption, the sight sleeps after a certain period of inactivity. In such cases, you can easily restart or resume your shoot with the shake awake technology. Just shake the Holosun HS515C once and your device is good to go!


The Holosun HS515C is essentially the best fit for combat shooting. So rifles that are best suited for such a purpose might be preferred here. The sight comes with a 1/3 Co-witness quick to detach mount with a removable spacer. This means that you can easily remove and refit the sight on almost all sorts of rifles without losing much time to it.

Scope vs Sight

Well, it can’t get more basic than this. A sight is basically a scope without magnification. So if you are looking for versatility in terms of magnification and range, then this is what you need. But if there is a fixed range you wish to focus on and you require more accuracy, then sights are better. Furthermore, sights have better variations of optical features like red dot sights, reflex sights, or holographic sights.

Which color LED is best suited for hunting – red or green?

Though red is the most popular one, green is what is essentially ideal. Our eye is well fitted to absorb the wavelength of a green wave better than a red one. This is why when the same intensity of green and red lights are emitted, the green appears to be brighter. Also, green is less harmful and pungent for the human eye. Nevertheless, one has to accept the reality that a green dot scope or sight will definitely cost you more than a red one.

Is Holosun a good company?

Holosun might not have stayed for ages but it is definitely trustworthy. This California based optics manufacturing company rests on the motto of producing technologically advanced, high-quality optics at an affordable price. They are definitely a good company especially if you are looking for red dot and laser sights.


Well, there goes our review of the Holosun HS 515 C red dot sight. As you may have already figured out, the device is best used in the military for close to medium range combat shooting. The reticle features and the highly reliable battery life makes it suitable for this venture. Many users have identified that this sight is definitely to be placed a rung above EOTech is terms of features as well as performance.

Nevertheless, there are few who would prefer spending a few more dollars and owning an Aimpoint for themselves. Cool. But let me just enlighten you on the fact that Holosun does borrow certain feature ideas like the battery life from Aimpoint but it also adds a lot of its own specificities to it. Which is why the device is a must-have. There is a lot offered for the given price range – something that most companies do not do! Do checkout their generic FAQs before buying.

That being said, your choice is yours. Even if you choose to own another device at the time being do come back and please try again later. Cause this beauty should be experienced at least once. I would recommend it any day, even in my sleep. The rest is up to you. See you later then. Let us know how much you loved this sight and do spread the word around. Happy Hunting to you!
