Features Of Holosun 507C VS Holosun 508T

Here are a few features and benefits that can assist you in comprehending everything you need to know to select the best optic.

1. Material and Durability

Holosun 507C 

The Holosun 507C is constructed using 7075 T6 Aluminum. So, it’s tough; you can count on it. As a professional shooter, I put it through the wringer: high recoil, rapid transitions, and even a couple of accidental bumps against hard surfaces. 

The 507C stood its ground and showed zero sign of wear or zero shift. While the anodized surface finish adds an extra layer of protection, the material itself is strong enough to withstand everyday wear and tear. 

The aluminum construction makes it lighter, but that doesn’t mean it compromises on durability. The unit weighs 1.44 ounces, which is good for quick aiming without adding bulk.

Holosun 508T 

The Holosun 508T takes things up a notch with a grade 5 titanium housing. Titanium is lighter and stronger than aluminum, making it more suited for extreme conditions. My experience shooting with it was nothing short of impressive. 

The sight took everything I threw at it like a champ, showing no signs of degradation. Titanium is also more corrosion-resistant, giving it an edge in more humid or salty environments. 

The sight feels indestructible, and the weight is virtually the same as the 507C. In real-world tests, like fast drawing and target acquisition, the material’s added durability gives you peace of mind that your sight will survive, even in tough conditions.


Holosun 508T takes the lead in material and durability, thanks to its titanium construction.

2. Battery Life and Power Source

Holosun 507C 

The 507C runs on a CR1632 battery, promising up to 50,000 hours of battery life. That’s exceptional, right? The side-mounted tray makes replacing the battery a cinch. 

But what’s even cooler is its Solar Failsafe feature. When I was out at the range, the solar panel took over seamlessly when the ambient light was sufficient, saving battery life. 

The transition was so smooth I hardly noticed. However, this feature is dependent on your environmental lighting. If you’re shooting in low-light conditions, you’re back on battery power; no two ways about it. But still, that’s a lot of shooting time before you need to worry about changing that battery.

Holosun 508T 

Like its counterpart, the 508T also boasts a 50,000-hour battery life, running off a CR1632 battery. In my testing, the Solar Failsafe feature worked impeccably, just as it did with the 507C. 

The solar power kicks in when natural or artificial light is adequate, preserving your battery. Honestly, it’s a relief knowing your sight won’t fail you if you forget to change the battery. 

Even when the light levels changed abruptly during my shooting session, the sight adjusted its reticle brightness accordingly. So, you get a stable, uninterrupted shooting experience.


It’s a tie. Both the Holosun 507C and 508T excel in battery life and power source options.

3. Reticle and Brightness Settings

Holosun 507C 

The 507C offers a red 2 MOA Dot and a 32 MOA Circle, which is pretty standard yet effective for both pinpoint accuracy and quick target acquisition. 

During my tests, the brightness settings were quite versatile. With 10 daylight and 2 night vision settings, it caters to a variety of scenarios. I particularly enjoyed the crispness of the reticle, making long-distance shots a bit easier. 

Holosun 508T 

The 508T also features a red 2 MOA Dot and a 32 MOA Circle, but it feels a tad sharper, maybe because of the titanium housing or perhaps the superior LED. 

The 10 daylight and 2 night vision brightness settings give you flexibility for any situation. While shooting, the reticle’s brightness adjusted well to the environmental light, providing a clear and crisp sight picture, even during rapid target transitions.


The Holosun 507C slightly edges out the 508T in reticle and brightness settings due to its sharper image quality.

4. Lock Mode Functionality

Holosun 507C 

Lock Mode on the Holosun 507C serves its purpose quite well. During my tests, it effectively prevented inadvertent changes to the sight settings, making it highly reliable. 

It’s more than just a button press; it’s a protective layer that saves you from potentially critical errors. The user interface, accessible via the T10 L Key, was straightforward to navigate, leaving little room for operational mistakes. 

In high-stress shooting scenarios, a feature like this contributes significantly to accuracy and confidence.

Holosun 508T 

In contrast, the Lock Mode on the Holosun 508T is fortified by its Grade 5 titanium housing, adding an extra layer of robustness. During my range tests, this translated into a heightened sense of reliability for the locking feature. 

The mechanism itself felt firmer, and more resilient against both unintentional button presses and physical impact. It was as if the titanium housing was an extra insurance policy for the lock mode.


Holosun 508T is the clear winner here. The robust titanium housing lends extra dependability to the Lock Mode, making it superior in terms of both reliability and resilience against inadvertent setting changes.

5. Window Size

Holosun 507C 

The window size of the Holosun 507C measures 0.63×0.91 inches, optimal for quick target acquisition. My hands-on test revealed the window size to be sufficiently large for a clear sight picture, yet not so expansive as to create distractions. 

The dimensions fall within the optimal range for sustained focus and quick target transitions.

Holosun 508T 

The Holosun 508T shares the same window dimensions as the 507C. What sets it apart is the added structural integrity provided by the titanium housing, which frames the window subtly but effectively. My field tests indicated quicker target acquisition, as the window design funneled my visual focus more efficiently towards the reticle.


Holosun 508T excels in this feature comparison. The titanium frame around the sight window subtly enhances visual focus, contributing to quicker and more accurate target acquisition in high-stress scenarios.

6. Eye Relief

Holosun 507C 

Eye relief on the Holosun 507C is something that can’t be overlooked. In my personal tests, I was truly pleased with its limitless, parallax-free eye relief. 

This feature allows you to maintain a clear and stable sight picture even as you shift your position. The multi-layer lens coating is another benefit. It effectively prevents stray light from entering the sight, ensuring that the image remains crisp. The parallax-free nature means the reticle stays on target, even when you’re on the move or switching aim.

Holosun 508T 

The Holosun 508T mirrors the 507C when it comes to eye relief, offering the same limitless and parallax-free advantages. During my time at the range, this feature proved just as invaluable on the 508T as it did on the 507C. 

The multi-layer lens coating is similarly effective in keeping unwanted light at bay, which is crucial for precise aiming. Despite being packed in tougher titanium housing, the 508T maintains the level of clarity and visual comfort that the 507C offers.


It’s a tie. Both the 507C and 508T deliver exceptional performance in eye relief, making them equally dependable for various shooting scenarios.

7. Price Comparison

Holosun 507C 

When it comes to price, the Holosun 507C generally has an edge for those counting their pennies. You can expect to save somewhere in the ballpark of 55 to 60 dollars compared to its 508T counterpart. That’s not an astronomical difference, but hey, every dollar counts. 

These savings could potentially go towards ammo or other accessories you might need. Despite the lower price, the 507C still boasts solid features, making it a cost-effective choice without sacrificing too much on quality.

Holosun 508T 

The Holosun 508T is usually a bit pricier, but let’s consider what you’re getting for that extra cash. The titanium housing, to begin with, provides added durability and reliability.

 If you’re someone who values these aspects and is willing to splurge a little more for them, then the 508T could be your pick. While the price difference isn’t enormous, it does reflect the higher-grade materials and perhaps a smidgen of extra confidence in your equipment.


If budget is a significant concern for you, the Holosun 507C takes a win. It offers most of the essential features you’d expect, at a somewhat lower price point.

Price Comparison: Holosun 508T Vs Holosun 507C

Due to the various factors that influence sale prices, there are many discrepancies in cost between multiple vendors or websites. However, because of the housing substance used in 508t, Holosun 508t is much more costly than 507c.

The cost is extremely important for many shooters, but having a good optic is also essential. If you want a more long-lasting optic and are willing to pay a higher price, go for the Holosun 508t. As a shooter, I’ll advise you never to skimp on the optic’s quality.
