Burris FastFire 3 Review: Is it Still Worth it? [2025] Overview
The Burris FastFire 3 is a compact, lightweight reflex sight designed primarily for handguns, but its versatility extends to shotguns, rimfire rifles, and even some pistol-caliber carbines. Its main purpose is to provide a fast, single-plane aiming solution that can significantly speed up target acquisition compared to traditional iron sights. The design philosophy is one of minimalism and ruggedness, favoring straightforward operation over complex feature sets.
This product is ideally suited for hunters, competitive shooters in practical disciplines, and those using a red dot for home defense. It’s also an excellent choice for anyone mounting an optic on a shotgun for turkey or deer hunting, where its light weight and durability are major assets. The FastFire 3 comes with a 3 MOA dot size, which I find to be a perfect balance for precise shots at distance and fast, close-range work. A key detail that shouldn’t be overlooked is the included Picatinny mount and the protective shroud, which adds a significant layer of durability against bumps and drops right out of the box.

Key Features & Performance
In my time with the FastFire 3, its performance has been defined by a few standout characteristics. It’s not the flashiest optic, but its key features are implemented in a way that promotes confidence and reliability in the field and on the range.
Durability and Weatherproofing
This is arguably the FastFire 3’s strongest suit. The housing is crafted from a high-strength aluminum alloy, and the sight is fully waterproof. I’ve subjected it to rain, dust, and the significant recoil impulse of a 12-gauge shotgun, and it has not faltered once. It maintains zero impeccably. The included protective shroud is a fantastic addition, acting as a built-in shield for the lens and body. Compared to some other micro red dots in its class, this extra layer of physical protection gives it a tangible edge for hard-use scenarios.
3 MOA Dot and Reticle Clarity
The 3 MOA dot is crisp and clear, with minimal bloom even at higher brightness settings. I found it to be the ideal size for a general-purpose optic. It’s small enough to allow for precise aiming at small targets or at longer distances, yet large enough to pick up very quickly in dynamic shooting situations. The glass is clear with a slight blue tint, but it’s never been a distraction or hindered target visibility in my experience. The dot itself is sharp, which is more important than a perfectly colorless lens.
Battery Life and Power Modes
This is the area where the FastFire 3 shows its age slightly. Powered by a common CR1632 battery, Burris rates it for about 10,000 hours of runtime. While this is sufficient for most uses, it falls short of the 20,000, 30,000, or even 50,000-hour ratings found on some modern competitors. The sight features three power modes: a manual high, a manual low, and an automatic setting. The auto-brightness mode works well in most conditions, but I did notice it could be slow to adjust when moving from a very dark area into bright sunlight, or vice-versa. For critical use, I often prefer to set the brightness manually.
Mounting System and Footprint
The FastFire 3 uses a proprietary mounting footprint. While it comes with an excellent Picatinny base in the box, directly mounting it to a slide often requires a specific adapter plate. This can feel a bit dated when compared to optics that use a more universal footprint like the Shield RMSc. However, the system itself is robust and secure once installed. The windage and elevation adjustments are clicky and positive, making zeroing a straightforward process.

Final Verdict
So, is the Burris FastFire 3 still worth your consideration in 2025? The answer is a resounding yes, with a clear understanding of what it is and is not. It is a proven, rugged, and highly reliable micro red dot that excels at its primary job. It is not a feature-laden optic with the longest battery life or the most modern mounting solution. For the right shooter, its strengths far outweigh its minor shortcomings.
Pros
- Battle-tested durability that inspires complete confidence.
- The 3 MOA dot is perfectly sized for versatility and speed.
- Simple two-button operation is easy to learn and use under pressure.
- Excellent value with the inclusion of both a Picatinny mount and a protective shroud.
Cons
- Battery life, while adequate, is surpassed by newer models.
- The proprietary mounting footprint can require an extra purchase for direct slide mounting.
- Auto-brightness sensor isn’t as responsive as on some higher-end optics.
I highly recommend the Burris FastFire 3 for hunters, especially on shotguns, for those wanting a rugged optic for a pistol-caliber carbine, and for anyone who values simplicity and proven performance above all else. You should look elsewhere if your primary concern is maximizing battery life for a dedicated defensive handgun or if you want the latest in mounting technology without any adapters.
What Customers Say About This Product
User feedback consistently reinforces the themes of durability and real-world performance that I experienced during my testing.
Mark T. “I’ve had this on my turkey shotgun for three seasons now. It’s been through downpours, bumped against trees, and has never lost zero. The battery is easy to change before each season, and it just works every single time.”
Sarah L. “As a new shooter, the simplicity of the FastFire 3 was a huge plus. I wasn’t overwhelmed with settings. I mounted it, zeroed it in about 10 minutes, and have been hitting steel consistently ever since. The included shroud gives me peace of mind.”
James K. “I use this on my competition pistol. The dot is clear and the sight is lightweight. The auto-brightness is good for most stages, but I usually just set it manually. It’s taken a beating from thousands of rounds and still runs like a champ.”
Ranger Dave “I wanted a red dot for my ranch rifle that could handle being knocked around in the UTV. This thing is tough. The glass is clear and the buttons are easy to press, even with gloves on. It’s a solid tool.”
