Who Should Get Burris Fastfire II

The Burris Fastfire II is an ideal choice for shooters who value precision, ease of use, and versatility. It’s particularly suited for those who engage in both recreational shooting and more demanding scenarios such as hunting or tactical operations.

Top 6 Features of Burris Fastfire II

1. Simplified Target Acquisition

The Burris Fastfire II revolutionizes target acquisition with its bright-red dot, which is a standout feature for rapid and accurate aiming. This 4-MOA red dot, prominent against any background, allows for quick eye alignment and target focus. 

The brilliance of the red dot is consistent across various lighting conditions, ensuring visibility in bright sunlight or dim indoor ranges. 

The sight’s parallax-free design enhances accuracy, allowing shooters to maintain a steady point of aim without the need for perfect eye position. This feature is crucial for dynamic shooting situations where rapid target engagement is essential.

My Testing

In my experience, the Fastfire II excelled in quick target acquisition. Whether in competitive shooting or hunting scenarios, the red dot was instantly noticeable, significantly reducing the time to align the sight and the target. 

The dot remained crisp and clear in different environments, from bright outdoor settings to more subdued indoor ranges.

2. Auto-Dimming & Brightness Sensor

The auto-dimming feature, coupled with the automatic brightness sensor, is an intelligent inclusion in the Fastfire II. This technology automatically adjusts the brightness of the red dot based on the surrounding light conditions.

In bright sunlight, the dot intensifies for clear visibility, while in darker environments, it dims to prevent overpowering glare. This adaptation is not only comfortable for the eye but also ensures that the red dot is always at the optimal brightness level for any given situation.

My Testing

During testing, the auto-dimming feature performed remarkably. Moving between different light conditions, the transition in dot intensity was seamless and unobtrusive. 

In bright outdoor conditions, the dot was vivid and easy to track, while in darker settings, it dimmed appropriately, maintaining visibility without being distracting.

3. Durability and Design

The Burris Fastfire II’s durability is attributed to its robust metal construction, making it both sturdy and reliable for all shooting conditions. The sight’s lenses are precision-ground and polished, ensuring a clear, crisp sight picture. 

Its waterproof design is an added advantage, protecting the sight in adverse weather conditions. The compact and lightweight nature of the Fastfire II makes it a versatile option for various firearms without impacting the balance or handling.

My Testing

My rigorous testing proved the Fastfire II’s resilience. Mounted on different firearms, from handguns to rifles, it withstood recoil and environmental stresses without any loss in performance.

The waterproof feature was tested under rainy conditions, and the sight maintained its clarity and functionality. The lightweight design was a boon, adding minimal weight to the firearms, thus not affecting maneuverability.

4. Windage and Elevation Adjustability

The windage and elevation adjustability in the Burris Fastfire II is a testament to its precision and versatility. These features allow shooters to fine-tune their aim, ensuring that shots land exactly where intended. 

The adjustments are user-friendly, with each click providing a tangible and precise change in the sight’s alignment. This level of control is crucial for long-range accuracy and for compensating for environmental factors such as wind and elevation differences. 

The locking mechanism for these adjustments ensures that once set, the settings remain consistent, providing reliability in various shooting conditions.

My Testing

During my testing, the adjustability of windage and elevation was straightforward and effective. The clicks were distinct and accurate, making it easy to dial in the exact settings needed for different shooting scenarios. 

The sight maintained its zero exceptionally well, even after repeated recoil, showcasing its reliability and precision.

5. Parallax-Free Design

Parallax-free sighting is a critical feature for any high-quality red dot sight, and the Burris Fastfire II excels in this aspect. The design ensures that the red dot remains stationary relative to the target regardless of the viewer’s eye position within the sight. 

This feature minimizes aiming errors and enhances shooting accuracy, particularly in fast-paced or dynamic shooting environments. It allows for more flexibility in head position and eye relief, making it easier to acquire and track targets quickly.

My Testing

Testing the parallax-free feature was impressive. The red dot remained consistent with the target point regardless of my eye position. 

This greatly enhanced my shooting speed and accuracy, especially in situations where quick target acquisition was essential.

6. Battery Life and Management

The Burris Fastfire II boasts impressive battery life, a crucial aspect for any electronic sight. The sight’s high-tech electronics, combined with its auto-dimming feature, contribute to extended battery life, with Burris claiming up to five years of use under normal conditions. 

This long battery life is a significant advantage, reducing the need for frequent replacements and ensuring the sight is always ready for use.

My Testing

In my testing over an extended period, the battery life lived up to expectations. 

The auto-off feature helped conserve battery power, and even after extensive use, the sight remained operational without any need for a battery change.

Footprint and Mounting Considerations

The Burris Fastfire II is designed with the Docter/Noblex mounting standard, a widely 

recognized and respected footprint in the optics industry. 

This standard ensures broad compatibility with a variety of firearm platforms, making the Fastfire II a versatile choice for different shooting disciplines. 

Its compatibility with the Docter/Noblex footprint allows for straightforward installation on handguns, rifles, and shotguns that are equipped with the respective mounting base. 

This feature simplifies the process of integrating the sight onto the firearm, ensuring a secure and stable mount, crucial for maintaining accuracy and reliability in various shooting conditions.
