Burris Optics has been delivering reliable pistol-mounted red dot sights for over 20 years, and now they’ve taken things a step further with the FastFire E. This new addition to their FastFire series is the company’s first enclosed emitter reflex sight, designed to work seamlessly on pistols, shotguns, and carbine rifles.
What sets the FastFire E apart is its rugged, monolithic aluminum housing and fully enclosed design. This makes it waterproof, shockproof, and fogproof — ideal for handling rough environments, whether you’re out hunting in the snow or shooting in muddy conditions.
What to Know About the FastFire E
At its core, the FastFire E features a 3.5-MOA red dot that’s “always on,” backed by a massive 60,000-hour battery life. Changing the battery is easy, too — thanks to a side-mounted compartment, you won’t lose zero when swapping out the CR2032 lithium battery.
Burris didn’t just focus on durability — they made sure the optics are crystal clear, too. The FastFire E has aspherical lenses that cut down on glare and improve target visibility. Plus, with eight brightness settings (including two for night vision), and the option of a red or green aiming dot, it’s built for versatility in any lighting.
And here’s the kicker: the sight window is a generous 22x17mm, giving you a wide, clear field of view. Combine that with 1X magnification, and you can keep both eyes open while shooting — great for staying fast and aware.
Built for Precision and Versatility
Need to fine-tune your aim? The FastFire E offers 100 MOA of adjustment for both windage and elevation. That means it works well with a variety of firearms, from handguns to rifles and shotguns. It’s also built to mount using the widely used Aimpoint ACRO footprint, so you’ll have no problem finding the right plate or slide cut to fit. Burris even includes a T10 tool for secure mounting.
Features You’ll Appreciate
Burris packed in some handy extras to make the FastFire E as user-friendly as possible:
- Automatic brightness reset ensures you won’t get caught off guard by sudden changes in light.
- Brightness lock and button lockout functions prevent accidental adjustments.
- Designed to handle extreme temperatures, from -4°F to +140°F.
Why Enclosed Emitters Matter
Enclosed emitter red dots, like the FastFire E, are gaining popularity because they’re tough and dependable. Unlike open designs, they keep the emitter fully protected from dirt, dust, and water, making them perfect for outdoor adventures, tough-duty use, or shooting in bad weather.
