Overview of Holosun 507C X2 and 407C X2
The Holosun 507C X2 and 407C X2 are popular red dot sights with key differences in reticle options and battery life. These compact optics offer durability and functionality for pistols and other firearms.
Specifications Comparison
The 507C X2 features a Multi Reticle System (M.R.S.) with a 2 MOA dot and 32 MOA circle. The 407C X2 has a single 2 MOA dot reticle.
Battery life differs between models:
- 507C X2: 20,000 hours with M.R.S.
- 407C X2: 50,000 hours
Both sights use a CR1632 battery and have Shake Awake technology to conserve power. They share similar dimensions and mounting footprints, fitting many pistol slide cuts and adapter plates.
The 507C X2 costs more due to its advanced reticle system. Both models offer multiple brightness settings and are compatible with night vision devices.
Design and Build Quality
These Holosun sights are built to withstand harsh conditions. They feature 7075 aluminum housings, making them lightweight yet durable. The optics are water-resistant and can handle recoil from various firearms.
Both the 507C X2 and 407C X2 have a low-profile design, minimizing bulk on pistols or other weapons. They include side-mounted battery trays for easy replacement without removing the sight.
The lenses on both models have multi-coated glass for clear views and reduced glare. Holosun’s Solar Failsafe technology provides a backup power source, enhancing reliability in critical situations.
Optical Features and Performance
The Holosun 507C X2 and 407C X2 offer different reticle options and brightness settings. These features impact their performance and user experience.
Reticle Types and Functions
The 507C X2 has three reticle options: a 2 MOA dot, a 32 MOA circle, and a combination of both. This versatility allows users to switch between reticles based on their needs.
The 407C X2 comes with a single 2 MOA dot reticle. While less versatile, this simplicity can be an advantage for some shooters.
Both models use LED technology for their reticles. This provides crisp, clear aiming points and contributes to their long battery life.
Brightness and Visibility
Both the 507C X2 and 407C X2 offer multiple brightness settings. They feature 12 brightness levels, including two night vision compatible settings.
The sights have auto-brightness sensors that adjust the reticle intensity based on ambient light. This helps maintain visibility across various lighting conditions.
Both models use Holosun’s “Shake Awake” technology. This feature conserves battery life by turning the sight off when not in use and quickly reactivating it with movement.
Mounting and Compatibility
The Holosun 507C X2 and 407C X2 share identical mounting features and compatibility. This makes them interchangeable on various firearms and mounting systems.
Footprints and Adapters
Both models use the RMR footprint, a widely adopted standard in the industry. This footprint consists of two sockets in the front corners and two screw holes in the center.
The front sockets are 22.5mm (0.89 inches) apart. This design allows for easy mounting on many popular handguns and rifles.
For firearms without a direct RMR cut, adapters are available. These adapters enable mounting on different slide cuts or Picatinny rails.
Installation Process
Installing the 507C X2 or 407C X2 is straightforward. Here’s a simple guide:
- Clean the mounting surface thoroughly
- Apply a small amount of thread locker to the screws
- Place the sight on the mounting surface
- Insert and tighten the screws to the manufacturer’s specifications
It’s crucial not to overtighten the screws, as this can damage the optic. Many users recommend using a torque wrench for precise tightening.
After installation, it’s important to zero the sight. This process may vary depending on the firearm and personal preference.
Battery Life and Power Management
The Holosun 507C X2 and 407C X2 both offer impressive battery life, but there are some key differences.
The 407C X2 boasts 50,000 hours of battery life on setting six. This long-lasting performance ensures reliability for extended periods.
In contrast, the 507C X2 provides 20,000 hours of battery life on setting six when using the MRS Reticle. However, if only the 2 MOA dot is used, its battery life matches the 407C X2 at 50,000 hours.
Both models feature Shake Awake technology. This smart feature conserves power by turning off the sight when not in use and reactivating it with movement.
The 507C X2 has an additional power management feature: a solar failsafe. This backup system uses ambient light to power the sight if the battery fails.
To maximize battery life on both models:
- Use lower brightness settings when possible
- Enable auto-shutoff features
- Store the sight in a dark place when not in use
These power management options help users maintain optimal performance and extend the time between battery changes.
Price and Value for Money
The Holosun 507C X2 and 407C X2 have different price points. The 407C X2 is generally less expensive than the 507C X2.
The main reason for the price difference is the reticle options. The 507C X2 offers three reticle choices, while the 407C X2 has only one.
For shooters who prefer a simple 2 MOA dot, the 407C X2 provides excellent value. It offers many of the same features as the 507C X2 at a lower cost.
The 507C X2’s multiple reticle options may justify its higher price for some users. It allows for more versatility in different shooting situations.
Both optics share key features like:
- Solar failsafe
- Shake Awake technology
- Long battery life
- Durable construction
The battery life of the 407C X2 is longer at 50,000 hours compared to the 507C X2’s 20,000 hours when using all reticles.
Ultimately, the choice depends on individual needs and preferences. The 407C X2 offers great value for those who don’t need multiple reticles. The 507C X2 provides more options at a higher price point.
