EOTech vs Holosun Hs510c – 10 Features Compared

holosun hs510c vs eotech

After spending hundreds of hours out on the range, the constant debate on Holosun Hs510c vs EOTech sights isn’t new to us at all. We figured it was time to make an in-depth comparison between these two optics. You’ll find out which has better focus, better battery life, and overall excellent quality in this guide.

The Holosun 510c is an Open Reflex Circle Dot Sight while the XPS2 is a holographic sight. The 510C reflex red dot sight uses a LED and an objective lens, while XPS2 uses mirrors and laser diodes to project the reticle. The 510c uses a single-cell CR2032 battery that provides up to 50 000 hours of the LED light. The XPS2 uses a single 123 lithium battery that provides 1,000 continuous hours at nominal setting 12 at standard room temperature.

The 510c has a 65 MOA ring and 2 MOA while the XPS2 has a 68 MOA ring and 1 MOA dot only ring. The Holosun 510c is submersible up to one meter, whereas the XPS2 can stay in the water up to 3m or 10 ft.

Comparing the key features

Price

It’s a no-brainer that the best holographic sights like the EOTech EXPS-2 are considerably more expensive than red dot sights. Holographic sights require more expensive holographic technology, and their manufacturing competition is relatively narrow. That said, the Holosun Hs510c is the clear winner in terms of price manufacturing costs.

Weight & Size

Generally speaking, holographic sights are relatively bulkier than reflex red dots. The EOTech XPS2 is usually mounted on a rifle, while red dot reflex sights are small enough to fit handguns.

The 510c is only 8.3 oz in weight, while the holographic optic weighs 9 oz with an adjustable click by 0 5 MOA. With this, the Holosun 510c takes another win.

Warranty

When it comes to the Holosun 510c vs Eotech warranty, the Eotech takes its first win. With Eotech XPS2 optics, you’ll get a Prestige Warranty that lasts up to ten years of protection due to defects in quality and material under regular use. With the 510c, you’ll get a Limited Lifetime Warranty covering its optical system for five years and its illumination and electronics for only three years.

Battery Life

The Holosun HSC510C uses a single-cell CR2032 battery that provides up to 50,000 hours of LED light and a solar panel that can run the sight without a battery. However, the Eotech holographic sight uses a single CR123 lithium battery that provides 1,000 continuous hours. CR2032 batteries are light, have high-density, small, inexpensive, high cell voltage, easy to stack for higher voltages, and long shelf-life. [1]

Another thing that impressed us is the Holosun’s shake and awake feature that sensors motion and automatically sleeps when idle. Because of this, our team gave another point to the 510c.

Parallax Adjustment

Both claim that they are free of parallax like most Vortex scopes. But since holographic sights seem more dependable in the parallax adjustment category than the reflex red dot sight, we decided to try both in the shooting range.

Although both seem to live up to their claims, we find the XPS2 more stable than the 510c in long-range shooting. Since XPS2 has a less parallax error like most vortex scopes, it won another point.

Ease of Use

Both optics come with a high-quality mount that allows absolute co-witness with back up iron sights and can mount in Weaver or MIL-STD-1913 rails. We find the Holosun 510c easier to use because it comes with a quick-detach mounting system with co-witness. It can even be mounted to any standard Picatinny rail system without any tools. With this one extra feature, the Holosun 510c gets another point.

Durability

Both optics are durable, having high-quality aluminum housings and protective hoods over their lenses. The XPS2 is waterproof up to 3m, while the 510c can only stay in the water for up to 1m. Even without the military track record of the XPS2, the 510c’s durability still has no complaints.

The 510c has MAO (Micro Arc Oxidation) surface treatment finish that can withstand more significant impact and heat over time. With their added features, we decided to give this category a draw.

Image Quality

Both come with different projection systems like the Vortex scope. The 510c uses LED with an objective lens, while the holographic Eotech XPS2 optic uses laser diodes and mirrors to project the reticle. After trying out the sights, we all agreed that the 510c’s reticles create more vivid colors, hence a better image quality. With this, the 510c takes another win.

Focus & Lens Clarity

It’s also best to consider their focus and clarity. The Holosun 510c allows switching between its circle dot reticle, 2 MOA dot, and the 65 MOA ring so shooters can tailor their reticle to their preference.

In contrast, the XPS2 provides 68 MOA ring and 1 MOA dot reticle. With its versatility, the Holosun wins this category.

Eye Relief

The Holosun Circle Dot Reticle provides excellent large target acquisition while retaining the 2 MOA dot precision for a small distant target. It also allows switching to its three reticle options. While both sights have unlimited eye relief, we find the reticle of the Holosun to be crisper than the XPS2’s holographic reticle that usually tends grainy at some point. With this, the 510c slams another win.

EOTECH or Holosun HS510c? We Choose...

In the battle between the Holosun Hs510c vs Eotech XPS2, we choose the Hs510c because it has a long-lasting battery life that we always consider purchasing our sights. Having a 50,000-hour battery life gives us the confidence to hunt without worrying about time. We also liked how this Holosun sight has an integrated QD mount for easy mounting and removal without using any tools. It also has three reticle options that cater to your preferred reticle.
