Features Comparison of Swampfox Sentinel Vs. Holosun 507K

1.  Battery Life

Swampfox Sentinel

Battery life is something you don’t want to fuss about, especially if you’re using your firearm frequently. Swampfox Sentinel has nailed it in this department. With a CR2032 battery, it promises a real-world battery life of two years, even if you carry your gun every single day. 

The ‘Shake ‘N Wake’ technology also plays a crucial role. If the sight has been motionless for about 4 minutes, this feature kicks in to conserve battery life. Once you move, it resumes its previous brightness level. 

Holosun 507K

Holosun 507K is no slouch when it comes to battery life, either. It boasts an impressive 50,000-hour battery life using a CR1632 battery. And get this: the ‘Shake Awake’ technology ensures that the sight isn’t consuming battery when not in use. 

You can set the sleep mode from 10 minutes to 12 hours or even disable it entirely. It’s like having a diligent sentinel (no pun intended) that knows when to sleep and when to jump into action.

Winner

Due to its large window and selection of various lens colors, Swampfox Sentinel wins.

2. Durability

Swampfox Sentinel

Durability is not something to overlook. Swampfox Sentinel is made from 7075 aluminum, hard coat oxidized, and is shockproof to 1,500 G forces.

It’s also waterproof. In my testing, this tiny powerhouse stood up to the challenges of an intense shooting session and even some unexpected rainfall. So yes, it’s built like a tank, albeit a miniature one.

Holosun 507K

Holosun also steps up its game with a housing made from 7075 T6 aluminum and an anodized surface finish. I’ve dropped it, bumped it, and exposed it to a variety of conditions.

 Like a reliable sidekick, it remained unfazed. It also features a side-mounted tray for battery replacement, making it slightly easier to deal with during maintenance.

Winner

It’s a tie. Both sights offer rugged durability that can withstand real-world conditions.

3. Reticle System

Swampfox Sentinel

Swampfox Sentinel uses a high-efficiency emitter projecting a 3 MOA red dot. Although it doesn’t offer multiple reticle options, it provides a crisp and bright dot for fast target acquisition. The manual version allows you to manually adjust brightness settings, giving you full control over the optic’s performance.

Holosun 507K

Holosun 507K takes customization to the next level with its Multi-Reticle System. You get a 32 MOA circle with a 2 MOA dot, allowing for quick sight picture selection for varying distances. During my tests, the large circle served as a great hold-over reference and was particularly helpful in guiding my eye to the 2 MOA dot.

Winner

Holosun 507K wins for its versatile reticle system. The ability to choose between different reticle styles adds value to this sight, making it more adaptable to various shooting scenarios.

4. Windage and Elevation

Swampfox Sentinel 

The Swampfox Sentinel offers smooth windage and elevation adjustments. These settings are crucial for achieving what’s known as a ‘zero,’ or hitting the target where you aim. 

What sets the Swampfox Sentinel apart is that once you set these adjustments, they’re permanent. That’s right, they’ll stick even if you accidentally drop the optic or give it a good knock. It stays zeroed in, making it a reliable choice for anyone who might find themselves in dynamic shooting situations.

Holosun 507K 

In the Holosun 507k, windage and elevation adjustments are also quite smooth. The maximum adjustment range is 50 MOA, with 1 MOA increments. 

While the Swampfox Sentinel boasts permanent settings, the Holosun 507k provides more room for fine-tuning. This might make it more suitable for those who often find themselves in various shooting conditions requiring frequent adjustments. 

The capacity for more precise calibrations means you can tailor the Holosun 507k to a wide range of scenarios, thereby increasing its versatility.

Winner

5. Weight

Swampfox Sentinel

At only 0.62 ounces, the Swampfox Sentinel is a lightweight contender in the world of optics. Weight can make a significant difference when you’re holding a firearm for an extended period. The lighter the optic, the less fatigue you’ll experience.

With the Swampfox Sentinel its minimal weight ensures that shooters can easily hold their firearms without getting bogged down. Its low weight also minimizes any disruption to the balance of the weapon, keeping your aim steady and true.

Holosun 507K

Weighing in at 1 ounce, the Holosun 507k isn’t far behind. Although it’s heavier than the Swampfox Sentinel by 0.38 ounces, the difference is hardly noticeable for most shooters. 

Its low weight means that the optic won’t drastically impact your ability to hold and aim your weapon. The one-ounce weight still falls in the category of ‘lightweight,’ making it suitable for prolonged use.

Winner

Swampfox Sentinel edges out with its even lighter frame.

6. Illumination Settings

Swampfox Sentinel 

When it comes to illumination settings, the Swampfox Sentinel provides ten different brightness levels, which adapt according to the model you choose. If you go for the Sentinel-A, the brightness will automatically adjust, freeing you from manual tinkering. 

Opt for the Sentinel-M, and you’re in control with manual adjustments. Some people find the highest brightness level a bit too glaring, but with ten options, it’s pretty easy to find your sweet spot. Additionally, an “awake shake” feature turns off the optic after 4 minutes of inactivity and powers it back up with slight movement.

Holosun 507K

The Holosun 507k ups the ante with 12 levels of brightness, two of which are geared specifically for nighttime use. 

There are three adjustment mechanisms: automatic, manual, and lockout, offering more versatility in various lighting conditions. The auto mechanism adjusts brightness in line with ambient light, while lockout keeps it constant, avoiding accidental changes.

Plus, a sleep mode can kick in after 10 minutes of inactivity, and you can customize the sleep settings.

Winner

Holosun 507k wins for its broader range of brightness settings and adjustment mechanisms.

7. Eye Relief

Swampfox Sentinel

Eye relief is crucial for comfort, especially for extended shooting sessions. The Swampfox Sentinel offers unlimited eye relief as long as the brightness is set appropriately. 

There is no parallax to worry about, which means the reticle will stay in place even as you move your head. This enhances your shooting experience, making it easier to maintain focus and accuracy over long periods.

Holosun 507K 

Holosun 507k also offers unlimited eye relief. Its bright and clear optics add to the comfort, allowing you to shoot for longer durations without straining your eyes. Being parallax-free further enhances its user-friendliness. 

With a well-adjusted brightness setting and optic clarity, you’re good to go for an entire day of shooting.

Winner

It’s a tie. Both the Swampfox Sentinel and Holosun 507k offer excellent eye relief, setting them apart as comfortable options for long shooting sessions.

8. Footprint and Mounting

What kind of footprint does the swampfox sentinel use, and how simple is it to mount one?

Swampfox Sentinel

Swampfox Sentinel has an RMSc footprint, allowing you to easily mount your optic to your weapon. Other options for attaching the swampfox sentinel include altering your pistol or utilizing an adapter plate, though neither option is particularly popular.

Holosun 507k

The RMSc footprint of Holosun 507k is identical to that of the Swampfox Sentinel. You won’t have any trouble getting this RMSc footprint onto your weapon.

Winner

Since the mounting footprints for the swampfox sentinel and the holosun 507k are identical, there is no winner.
